The theme area is manufacturing of engineering composites structures, specifically those which comprise continuous high performance fibres held together with a polymeric matrix. The relevant industry areas include aerospace, automotive, marine, wind energy and construction. The proposal demonstrates continuing and growing need in the UK polymer composites manufacturing sector for suitably technically qualified individuals, able to make positive and rapid impact on its international manufacturing competitiveness. Extension of a newly created Industrial Doctorate Centre in Composites Manufacture fills an existing gap in provision of industrially focussed higher level education in the UK, in the specialist discipline of polymer composites manufacturing. It has its centre of gravity in Bristol, with the rapidly expanding National Composites Centre (NCC) the natural home-base for the cohorts of composites manufacturing Research Engineers embedded in the composites manufacturing industry. This new hub of applied research activity focussed at TRL 3-5 is different from but highly complementary to the outputs of composites manufacturing PhD students within the EPSRC Centre for Innovative Manufacturing in Composites (CIMComp), working on more fundamental research topics in composites manufacture at TRL 1-3. Achieving a clearer definition of the industrial composites manufacturing challenges and of new knowledge base requirements will provide direction for the industrially relevant accompanying fundamental research. The EPSRC Centre for Innovative Manufacturing in Composites has established and maintains close management overview of this IDC , as well as fostering links with related CDTs within the wider High Value Manufacturing Catapult, initially specifically the AMRC Composites Centre IDC in Machining Science. Over time such connections will establish a critical mass of industrially focussed manufacturing research activity in the UK, raising the national and international status of the EngD brand in the composites industry, in academia and in professional institutions by targeted dissemination through CIMComp in conjunction with the NCC

Fibre-reinforced composites are finding increased usage in load-bearing structures in a variety of applications in marine, automotive and rail transport industries owing to their specific strength and stiffness properties. A serious problem with these composite materials, particularly glass-reinforced polymeric composites, which are the most prevalent in marine and other surface transport applications, is that they support combustion and in fire conditions burn, most often with heavy soot and smoke. Insulation can reduce the fire hazard, but does not eliminate it. Moreover the insulation adds weight and cost to apply.The combustible part of the composite is organic resin matrix. Most common method of fire retarding the resin and hence, the overall composite is the physical and chemical modification of the resin by either adding fire retardant element in the polymer backbone or using fire retardant additives in the resin. For polyester or vinyl ester resins, usually halogenated chemicals are used. While the presence of halogen significantly reduces the flammability of the resin, due to increasing environmental awareness and strict environmental legislations thereof, halogen - containing fire retardants are being strictly scrutinised. When non-halogen flame retardants are used, invariably they are required in large quantities (>30% w/w) to achieve required level of fire retardancy. The high concentrations of additives however, can reduce the mechanical properties of the composite. Moreover, they also affect resin's processability for resin transfer moulding technique, commonly used for these types of composites. We propose here a step change in the resin matrix by reducing the combustibility of vinyl ester and/or polyester resin by co-blending with inherently fire retardant resins, such as phenolic or melamine-formaldehyde resin.This proposal is a joint attempt by 'Fire Materials' group at the University of Bolton and 'Fluid Structure Interactions Research Group (FSIRG) at the University of Southampton to develop, construct, test and model novel, fire-retardant composites, initially for marine applications. The principal focus is to develop a modified polymeric matrix to reduce the combustibility of the vinyl ester or polyester resins by blending with appropriately modified phenolic and melamine resins, which will increase the thermal stability and char-forming capacity of the matrix. The physical and chemical properties of the modified resin will be optimised to enable: (a) the resin to be infusible for moulding leading to good processing ability: (b) low temperature cure capability to maximize compatibility and bonding with glass fibres; and (c) up-scaling to produce large laminates and structures. It is proposed that two different approaches will be taken: the first one 'Material' based, mainly by Bolton, and the other 'Structure' based, to which both Bolton and Southampton will contribute. The specific tasks include resin blending, chemical / physical modification of the resin, process modelling and resin infusion, composite laminate preparation and flammability evaluation. The composite laminates and structures thus produced are expected to comply with the fire performance requirements contained in the International Convention for the Safety of Life at Sea (SOLAS) as `IMO/HSC Code (Code of Safety for High Speed craft of the International Maritime Organisation). Additionally, the structural performance of the composite would be expected to be comparable with current glass/vinyl ester. We also propose to conduct fire performance modelling, mechanical characterisation and progressive damage analysis from a structural design viewpoint.We expect these composites to find applications also in other engineering arenas for which low-weight, thermally resistant and fire-retardant structures are increasingly being sought.

The objective of CHAMPION is to develop and demonstrate that novel bio-based polymers can be efficiently synthesised and applied in high-performance applications, beyond plastics, where the current petrochemical-derived materials are not fully fit for purpose. Technologies to be developed in CHAMPION include the reductive amination of bio-based chemicals to create novel sustainable diamine monomers, application of aza-Michael chemistry onto fully bio-derivable polymers, and bio-based unsaturated polyesters from secondary alcohol diols on a kilogram scale. The new materials will be specifically circular by design and assessed as such, thus making them superior to current materials by ensuring that (chemical) recyclability or biodegradability are possible. Applications will be tested by four relevant industry end-users in the coatings, textiles, home care formulation, and structural adhesives sectors. Up to 12 bio-based materials will be subject to advanced performance testing after preliminary screenings of many more candidates. The toxicity of materials, their precursors, and break-down products (e.g. during biodegradation) will be evaluated, as well as the environmental, economic, and social impact of the new bio-based value chains these materials create (safe by design). A cradle-to-grave sustainability assessment will use the benchmarks set by commercial products to quantify performance, resource efficiency, and reduced greenhouse gas emissions. The producers of two bio-based chemical intermediates in the consortium will form new cross-sector interconnections with the four end-users creating increased business and job opportunities. Dissemination and exploitation of results will be conducted to establish the basis of new value chains and inform Standards fit for describing new applications of bio-based products. At least two bio-based materials are targeted to reach TRL 5, with others in the pipeline for further development as part of the legacy of the project.
