The high specific properties of composite materials have long made them of interest in space applications, where despite significant reductions over the years it still costs around $15 dollars per gramme of payload to get to Low Earth Orbit (LEO). However, significant challenges remain in terms of producing material systems capable of withstanding the harsh environments, manufacturing light weight components precisely, and developing innovative solutions to enabling future space missions. At the Bristol Composite Institute (BCI), several research activities are targeted at developments that will enable further utilisation of composites in space applications. These can broadly be grouped under three main challenges.

Challenge 1: Getting to space.

While the specific properties of composite materials are high, realising the true potential for lightweighting requires reliable defect free manufacturing as well as significant tailoring of the amount of material and orientation of fibres in different regions of the part. To this end, there have been two key developments at the BCI that promise to contribute to extreme light-weighting. WrapToR, or Wrapped Tow Reinforced, truss structured, led by Dr Ben Woods, combines the high specific properties of composites with the high geometrical efficiency of truss structures and the efficient and highly automatable wrapping process.

A manufactured tow steered cylinder In parallel, development of fibre steered composite structures, led by Prof. Byung Chul (Eric) Kim, has had several successful steps towards commercialization. Specifically, a recent academic – industrial collaborative effort, led by the European Space Agency (ESA), which designed and manufactured Rapid Two-Steered (RTS) cylindrical structure, see Figure 1, clearly shows its potential for launch vehicles, where the design focus is not on the strength but on the structural stability during launching. The produced structure was nominated for a JEC Composites Innovation award in 2022. This study, which is now being followed by an ESA-funded project to apply the same methods to a full scale space structure in collaboration with a prime space contractor, was led by Dr Rainer Groh in collaboration with a BCI spin-out company, iCOMAT, which is commercialising Continuous Tow Shearing (CTS) technology after the techniques was first developed within a BCI research project. iCOMAT are proactively engaging with the space industry having secured £4.8M from the UK Space Agency (UKSA) and very recently a further £22.5M Series A from venture capital, a rare feat for composite start-ups.

Looking forward, next-generation automated composites manufacturing technologies are needed to enable highly efficient and complex composite structures that cannot be manufactured with current technologies. At BCI, 3D CTS technologies, see Figure 2, are under development which can manufacture complex space structures such as domes and nose cones without defects (see further reading for publication).

Challenge 2: Surviving space.

Once gravity has been overcome, the materials that remain in space will be exposed to the extremely damaging effects of atomic oxygen, extreme temperatures and thermal cycling, galactic cosmic radiation, and other challenging environmental effects. To address these challenges Prof. Ian Hamerton has led and supervised several research activities around developing new composite materials. Current projects are funded by the UK Space Agency (UKSA) and the Defence and Security Accelerator (DASA) and include collaborations with the National Composites Centre (NCC) in two high profile ESA programmes.

Initial developments began in 2017, when Oxford Space Systems funded a PhD studentship to study material survivability under space conditions. This work resulted in a family of polybenzoxazine (PBZ) nanocomposite resins, with enhanced resistance to degradation from the highly damaging effects of atomic oxygen, which has subsequently been studied in several research projects.

These developments have led to the BCI contributing four composite samples to an experiment in the Euro Material Ageing Facility on the Bartolomeo module onboard the International Space Station (ISS). The samples were prepared with UKSA funding and are based on three PBZ resins and a novel cyanate ester resin, also designed in BCI. Transportation to the ISS on a SpaceX Dragon launch vehicle is planned for the autumn of 2024; where the samples will spend up to 18 months, orbiting the Earth, before being returned for further analysis. This is part of a £3.5M Euro Materials Ageing 1 campaign (funded jointly by ESA and CNES), designed to examine the effects of the LEO environment, see Figure 3, on 45 materials drawn from 15 international teams.

In parallel, Prof. Hamerton’s team is also conducting projects to investigate chemically modified variants of the PBZ resins for their shielding characteristics towards galactic cosmic radiation, as well as the effects of LEO on the efficiency of thin (0.3 mm) deployable laminates. Another line of research is developing self-healing variants of PBZ polymer matrices, with the aim of improving the resilience of the composites against high velocity impacts from space debris – which is an important consideration for the final challenge.

Challenge 3: Staying in space

Once the payload is in space and resilient to the harsh environment, the goal now becomes to stay there and operate for as long as possible. With space agencies shifting their focus towards longer missions and even extraterrestrial habitats, cradle-to-cradle materials and processes that enable in-orbit and off-planet repair and manufacturing will become critical. In this, both novel material and manufacturing developments within the BCI play a crucial role.

Increased use of high performance thermoplastics as well as the potential to use reclaimed fibres using the patented HiPerDiF process, currently being commercialised as AFFTTM by another BCI spinout, Lineat Composites, combined with either fibre steering technologies or the WrapToR process, may enable low cost and scalable manufacturing. The specific coupling of HiPerDiF material and the WrapToR process is the current focus of a collaborative PhD project and related proposals to extend this work have recently submitted to the UKSA and ESA. Furthermore the WraptToR process has also been adapted into an extrusion like process, known as “TrussTrusion”, which could allow for compact payloads of raw materials which are then turned into the structural components once in space, or for re-production of recycled materials into new structural elements.

Outlook

While the challenges are great, the research already carried out and current developments are providing the building blocks and cornerstone technologies needed to enable the future of space exploration and travel. Providing both improved performance and sustainability, the research at the BCI is well placed to lead the way in the 21st century.

Acknowledgements

The challenges in developing new material systems and manufacturing process for space applications are profound, so it takes the efforts of many. Within the BCI contributions have been made by PhD researchers, past and present, post-doctoral researchers, academic staff, and our collaborators around the world including colleagues at the National Composites Centre.

CoSEM CDT STEM Outreach Day

Posted on 03/06/2024 by jo.rich

On the 20^th May, our CoSEM CDT hosted a STEM Outreach Day for a group of 40 Sixth-Form pupils from Katharine Lady Berkeley’s School in Gloucestershire. Led by the current CDT and PhD students, there were four activities that ran throughout the day, highlighting the exciting opportunities in Composites Engineering.

The EPSRC Centre for Doctoral Training in Composites Science, Engineering and Manufacturing (CoSEM CDT) welcomed Sixth Form pupils from Katharine Lady Berkeley’s (KLB) School in Gloucestershire. The CoSEM CDT students and Aerospace PhD students led activities that showcased the work they are engaged in and gave a taster of the type of exciting research being done in the programme.

After a Welcome from Dr Jemma Rowlandson and mini-lecture on Aeronautics from CoSEM Student Matthew Lillywhite, the pupils spent the day in General Engineering laboratory for a variety of hands-on activities. One activity, created by Dr. Ben Woods, was the creation of an aeroplane wing which required pupils in small groups to make decisions to craft a wing that took into consideration aerodynamics and the lift/drag ratio.

The KLB pupils also utilised a crushing apparatus devised by the University’s NextCOMP research team. Using jelly and dried pasta, the pupils were tasked with creating a sample that could withstand the most weight. In an additional NextCOMP activity, the pupils experimented with reinforcing chocolate bars and seeing how they performed under a pendulum test.

The final activity was to create a marble run, and under guidance from Dr Jemma Rowlandson the groups competed to build and test marble runs that met certain parameters.

Jurg Laderach, Maths teacher from KLB school said: “I was so impressed by the interactions between your department and our students. This is exactly how outreach should be done! I overheard many good conversations about career options and your students were brilliant at encouraging our students to choose the path that is right for them and go with what they enjoy. Your students talked with infectious passion about what they do.”

Additional support to run the day was given by: Jo Gildersleve (NextCOMP), Dr Jemma Rowlandson, Dr Ben Woods and Matthew Lillywhite, UoB Active Outreach team, and the CDT Directors and Staff.

CIMComp Hub Storytelling Workshop Review

Posted on 03/05/2024 by jo.rich

by Umeir Khan

Creating a compelling and impactful story can be challenging. Fortunately, there are tools at hand to engage our audiences and craft a message that is pitch-perfect.

Following on from the success of prior workshops coordinated by the CIMComp Researcher’s Network, early April saw a fantastic turnout from current PhDs/EngD students for the “Storytelling for Engagement” activity, hosted at the University of Nottingham’s campus, and delivered by material scientist / professional storyteller – Dr Anna Ploszajski.

Many items of consideration were brought up: the type of audience you are presenting to, understanding their motivations and playing with the narrative hooks that drive the dramatic tension in a story. Unsurprisingly, a lot of parallels can be found in our favourite films, the ‘what if?’ that starts the journey for a protagonist to the ‘what if’ that sparks our own research.

Overall, it was a splendid event which helped demystify the route to effective research communication and impact. Highly recommended!

Mystery of moths’ warning sound production explained in new study

Posted on 09/02/202414/06/2024 by jo.rich

The workings of the ultrasonic warning sounds produced by the wings of a species of moth have been revealed by researchers at the University of Bristol.

Bristol Composites Institute (BCI) Academics Prof. Alberto Pirrera and Dr. Rainer Groh, along with Prof. Marc Holderied and Research Associate Dr. Hernaldo Mendoza Nava in Biological Sciences at the University of Bristol have successfully had a paper published in the ‘Proceedings of the National Academy of Sciences’ (PNAS).

The scientists recently discovered that moths of the genus Yponomeuta (so-called ermine moths) have evolved a very special acoustic defence mechanism against their echolocating predators—bats.

Ermine moths produce ultrasonic clicking sounds twice per wingbeat cycle using a minute corrugated membrane in their hindwing. Strikingly, these moths lack hearing organs and are therefore not aware of their unique defence mechanism, nor do they have the capability to control it using muscular action.

In the study, published today in Proceedings of the National Academy of Sciences, an interdisciplinary team of engineers and biologists from Bristol show how individual ridges of a corrugated patch in the hindwings of ermine moths snap-through because of in-flight wing folding. The sudden snap-through of these features vibrates an adjacent membrane, significantly amplifying the strength and direction of the produced sound. Owing to its passive in-flight actuation, this sound-producing organ is known as an ‘aeroelastic tymbal’.

Marc Holderied, Professor of Sensory Biology at the School of Biological Sciences, explained: “Our goal in this research was to understand how the corrugations in these tymbals can buckle and snap through in a choreographed way to produce a chain of broadband clicks. With this study, we unfolded the biomechanics that triggers the buckling sequence and shed light on how the clicking sounds are emitted through tymbal resonance.”

The study’s first author, Hernaldo Mendoza Nava, who investigated the mechanics of the aeroelastic tymbal as a PhD student at the EPSRC Centre for Doctoral Training in Advanced Composites for Innovation and Science of the Bristol Composites Institute (BCI), said: “Sound production and radiation is linked to mechanical vibration, for example in the skin of a drum or a loudspeaker.

“In ermine moths, the snap-through buckling events act like drumbeats at the edge of a tymbal drum, exciting a much larger portion of the wing to vibrate and radiate sound. As a result, these millimetre-sized tymbals can produce ultrasounds at the equivalent level of a lively human conversation.”

To uncover the mechanics of the aeroelastic tymbal, Hernando combined state-of-the-art techniques from biology and engineering mechanics. The biological characterisation of the wing’s morphology and material properties ultimately led to detailed computer simulations of the snap-through response and sound production that match recorded moth signals in frequency, structure, amplitude, and direction.

Rainer Groh, Senior Lecturer in Digital Engineering of Structures at the BCI added: “The integration of various methods across the sciences with a consistent information flow across discipline boundaries in the spirit of ‘team science’ is what made this study unique and a success. In addition, without the amazing modern capabilities inimaging, data analysis and computation, uncovering the mechanics of this complex biological phenomenon would not have been possible.”

The discovery will help researchers understand many other insect species with similar sound production mechanisms, filling a page of anti-bat acoustic defences in the book on the age-old arms race between echolocating bats and their insect prey.

Structural buckling and sound production are rarely studied together, despite being reciprocal phenomena. In addition, buckling occurs as a sudden large deformation which can be attractive as a shape-changing mechanism in the field of morphing structures, such as in the aerospace industry, where engineers are looking to optimise the aerodynamic performance of wings.

Alberto Pirrera, Professor of Nonlinear Structural Mechanics at the BCI, concluded: “In the realm of engineering design, nonlinear elastic responses, such as buckling and snap-through instabilities, have traditionally been perceived as failure modes to be avoided. In our research, we have been advocating a paradigm shift and have demonstrated that buckling events can be strategically leveraged to imbue structures with smart functionality or enhanced mass-efficiency. Yponomeuta’s aeroelastic tymbal embodies the concept of beneficial nonlinearity.

“The natural world, once again, serves as a source of inspiration.”

The research team anticipates that through bioinspiration, aeroelastic tymbals will encourage novel developments in the context of morphing structures, acoustic structural monitoring and soft robotics.

How can experienced professionals find research projects in their niche area?

Posted on 31/01/2024 by jo.rich

Many experienced professionals can easily find research projects in their niche area, but young PDRAs and PhD students may not know how to find them. Research projects can offer opportunities for learning, networking, and career advancement. However, finding research projects that match one’s skills and interests can be challenging. For that reason, we will introduce some strategies and resources for finding research projects in your niche area.

Identify your research interests and skills.

Identifying your research interests and skills involves introspection into your academic background, personal passions, and career objectives. Questions like, “What are the primary themes or issues that captivate me?” and “What gaps or challenges exist in my field of study?” can guide this reflection. Additionally, consider the skills or methods you enjoy using or learning, and ponder how you wish to contribute to the progress of knowledge or society.

To pinpoint your research interests and skills, explore diverse sources of information and inspiration. This may include perusing academic journals, books, or websites pertinent to your discipline. Seek input from current or past professors, colleagues, or peers who share your interests. Delve into online databases or platforms listing research opportunities or projects and explore professional associations or networks offering guidance for researchers.

To find meaningful projects, look for titles such as research assistant, research officer, or research specialist in relevant fields. Utilize keywords when searching on platforms like LinkedIn and ResearchGate to discover valuable opportunities.

Explore existing research projects and opportunities.

One of the crucial skills for a researcher is the ability to investigate existing research projects and opportunities. This skill aids in discovering new collaborators, recognizing gaps in the literature, and identifying potential funding sources. Here are some suggestions on how to explore existing research projects and opportunities:

– Utilize online databases and platforms that aggregate research information, such as Google Scholar, ResearchGate, Scopus, and others. Conduct searches based on keywords, topics, authors, institutions, or citations to locate pertinent research papers, projects, and researchers.

– Attend conferences, workshops, seminars, and webinars aligned with your field of interest. Stay informed about the latest developments, trends, and challenges in your research area while networking with fellow researchers who share your interests. Additionally, consider presenting your own work to receive feedback from peers and experts.

– Join professional associations and societies that represent your research domain. Gain access to their publications, newsletters, events, and membership directories. Participate in committees, working groups, or special interest groups to contribute to their activities and initiatives.

– Initiate contact with potential mentors, advisors, or collaborators working on topics or methods that intrigue you. Reach out through email, social media connections, or request a meeting to inquire about their current or past projects, research goals and challenges, and seek advice.

– Explore your institution’s research resources and opportunities. Check your department’s website, bulletin board, newsletter, or email list for information on ongoing or upcoming research projects, events, grants, or awards. Engage with colleagues, supervisors, or administrators to learn more about their research interests and activities.

Research out to potential collaborators and mentors

One of the key skills for a researcher involves reaching out to potential collaborators and mentors who can provide valuable feedback, guidance, and opportunities. However, many researchers face challenges in initiating and maintaining such professional relationships. Here are some effective tips for conducting research outreach:

– Clearly define your goals and interests before reaching out to anyone. Determine what you aim to achieve through collaboration or mentorship and what you can contribute in return. Whether it’s learning a new method, working on a specific project, or seeking career advice, consider how you can contribute to their research or objectives.

– Conduct thorough research on the individuals you intend to contact, including their background, publications, and current projects. Tailor your message to reflect your genuine interest and enthusiasm, and identify common connections, such as mutual colleagues, institutions, or interests, to establish rapport.

– Craft a concise and polite email for your initial contact. The first impression is crucial, so ensure your email is well-written, professional, and respectful. Briefly introduce yourself, explain the purpose of your contact, articulate what you hope to gain from the interaction, and inquire about their availability and preferred mode of communication. Be specific about your request yet remain flexible and considerate of their time and priorities. If relevant, attach your CV or portfolio, and provide a link to your website or profile.

– Follow up and maintain communication. If you don’t receive a response within a reasonable time frame, consider sending a gentle reminder or follow-up email after a week or two. However, avoid being overly persistent or pushy to prevent annoyance or pressure. If they agree to a conversation, prepare questions or topics for discussion, and be punctual, courteous, and attentive during the conversation. Express gratitude for their time and insights and follow up with a thank-you email afterwards. If they suggest any action items or next steps, promptly follow through and keep them informed of your progress.
