We will launch a new CDT, focused on composite materials and manufacturing, to deliver the next generation of composites research and technology leaders equipped with the skills to make an impact on society. In recent times, composites have been replacing traditional materials, e.g. metals, at an unprecedented rate. Global growth in their use is expected to be rapid (5-10% annually). This growth is being driven by the need to lightweight structures for which 'lighter is better', e.g. aircraft, automotive car bodywork and wind blades; and by the benefits that composites offer to functionalise both materials and structures. The drivers for lightweighting are mainly material cost, fuel efficiency, reducing emissions contributing to climate change, but also for more purely engineering reasons such as improved operational performance and functionality. For example, the UK composites sector has contributed significantly to the Airbus A400M and A350 airframes, which exhibit markedly better performance over their metallic counterparts. Similarly, in the wind energy field, typically, over 90% of a wind turbine blade comprises composites. However, given the trend towards larger rotors, weight and stiffness have become limiting factors, necessitating a greater use of carbon fibre. Advanced composites, and the possibility that they offer to add extra functionality such as shape adaptation, are enablers for lighter, smarter blades, and cheaper more abundant energy. In the automotive sector, given the push for greener cars, the need for high speed, production line-scale, manufacturing approaches will necessitate more understanding of how different materials perform. Given these developments, the UK has invested heavily in supporting the science and technology of composite materials, for instance, through the establishment of the National Composites Centre at the University of Bristol. Further investments are now required to support the skills element of the UK provision towards the composites industry and the challenges it presents. Currently, there is a recognised skills shortage in the UK's technical workforce for composites; the shortage being particularly acute for doctoral skills (30-150/year are needed). New developments within industry, such as robotic manufacture, additive manufacture, sustainability and recycling, and digital manufacturing require training that encompasses engineering as well as the physical sciences. Our CDT will supply a highly skilled workforce and technical leadership to support the industry; specifically, the leadership to bring forth new radical thinking and the innovative mind-set required to future-proof the UK's global competitiveness. The development of future composites, competing with the present resins, fibres and functional properties, as well as alternative materials, will require doctoral students to acquire underpinning knowledge of advanced materials science and engineering, and practical experience of the ensuing composites and structures. These highly skilled doctoral students will not only need to understand technical subjects but should also be able to place acquired knowledge within the context of the modern world. Our CDT will deliver this training, providing core engineering competencies, including the experimental and theoretical elements of composites engineering and science. Core engineering modules will seek to develop the students' understanding of the performance of composite materials, and how that performance might be improved. Alongside core materials, manufacturing and computational analysis training, the CDT will deliver a transferable skills training programme, e.g. communication, leadership, and translational research skills. Collaborating with industrial partners (e.g. Rolls Royce) and world-leading international expertise (e.g. University of Limerick), we will produce an exciting integrated programme enabling our students to become future leaders.

Breakthroughs in the development of new materials have historically been achieved largely by trial and error. My vision is that there is a new generation of advanced hierarchical materials that has never been addressed and can be achieved by design. This new generation draws inspiration both from recent experimental observations in existing materials and from biomimetics, and is made possible by recent advances in modelling and manufacturing. The main challenges faced by today's composites industry include (i) damage tolerance, (ii) manufacturability and (iii) sustainability. I argue that (i) hierarchical micro-structural designs for composites will be more damage tolerant and achieve over 100% increase in fracture toughness, (ii) that hierarchical discrete carbon-fibre systems will simultaneously address manufacturing and performance needs of the automotive industry, and (iii) that recycled carbon fibres will find a high-value market as semi-structural parts by also exploiting hierarchical architectures. My proposal is to define these hierarchical micro-structures by design and to then develop suitable manufacturing methods to realise them in practice.

The 20th Century was characterised by a massive global increase in all modes of transport, on land and water and in the air, for moving both passengers and freight. Whilst easy mobility has become a way of life for many, the machines (planes, automobiles, trains, ships) that enable this are both highly resource consuming and environmentally damaging in production, in use and at the end of their working lives (EoL). Over the years, great attention has been paid to increasing their energy efficiencies, but the same effort has not been put into optimising their resource efficiency. Although they may share a common origin in the raw materials used, the supply chains of transport sectors operate in isolation. However, there are numerous potential benefits that could be realised if Circular Economy (CE) principles were applied across these supply chains. These include recovery of energy intensive and/or technology metals, reuse/remanufacture of components, lower carbon materials substitutions, improved energy and material efficiency. While CE can change the transport system, the transport system can also enable or disable CE. By considering different transport systems in a single outward-looking network, it is more likely that a cascading chain of materials supply could be realised- something that is historically very difficult within just a single sector. CENTS will focus on transport platforms where CE principles have not been well embedded in order to identify synergies between different supply chains and to optimise certain practices, such as EoL recovery and recycling rates and energy and material efficiency. It will also be 'forward looking' in terms of developing future designs, business models and manufacturing approaches so that emergent transport systems are inherently circular. More specifically, our Network will carry out Feasiblity and Creativity@Home generated research that will develop the ground work for future funding from elsewhere; provide travel grants to/from the UK for both established and Early Career Researcgers to increase the UK network of expertise and experience in this critical area; hold conferences and workshops where academics and industrialists can learn from each other; build demonstrators of relevant technology so that industry can see what is possible within a Circular Economy approach. These activities will all be supported by a full communication strategy focusing on outreach with school children and policy influence though agencies such as Catapults and WRAP.

Advanced composites have been used extensively in high performance lightweight applications ranging from aerospace, automotive to renewable energy sectors, with a global market of composite products over £60bn by 2017 together with a compound annual growth rate of 7% since 2011, and a projected £10bn growth in sales of composites in UK industry by 2030. However, with the ever increasing demand for zero-impact and sustainable development, the environmental impact of each stage from composite production to their end-of-life options should be considered to take the advantage of this high growth rate in the composite sector. Three important questions remain for the clean growth of the sector: (1) how can we manufacture the composites in an environmentally sustainable way, i.e. reduce the energy consumption for the rapid growing production needs; (2) how to effectively reduce, recycle, and reclaim valuable materials from end-of-life composite wastes; (3) how to truly reveal the lightweight feature of composites and reduce the overdesign in composites while avoiding unexpected catastrophic structural failures. This project will address all three questions by materials and manufacturing innovation, creating a circular economy for the composite industry by providing an extremely energy efficient and intrinsically safe manufacturing method based on recycled composite wastes as new functional fillers. With only 1% of energy consumption compared to current manufacturing methods, high performance composites with integrated new functions like deformation and damage sensing as well as de-icing will be manufactured without needs of even an oven. This new method will be tuned to fully comply with the processing requirements of existing high performance composite systems, reducing costs in capital investment, operational, and maintenance aspects. The new functions will also provide real-time health monitoring of components' structural integrity to enable condition based maintenance with high reliability. This research will be supported by a strong joint force from both academia (WMG, University of Warwick, and Massachusetts Institute of Technology, US) and UK industry (ELG Carbon fibres Ltd, and LMK Thermosafe Ltd), with leading expertise from polymer and nanocomposite processing, smart composites, to carbon fibre recycling and intrinsically safe heating applications, to ensure a great success of the project and a large impact on relevant research fields, as well as a direct contribution to addressing the UK Grand Challenges of "clean growth" and "future of mobility" and international competitiveness of the UK economy, with world leading development in lightweighting in transportation, manufacturing and efficient use of resources.
