The vast growth of interest in sustainability implies a substantial interest from transport OEMs in high performance bio fibre reinforced composites. Natural fibre polymeric composites have been used in different automotive non-load bearing components and have demonstrated the potential of this type of composites. The wood-based cellulose fibers are an important resource from the Swedish forest industry which can be used as pulp-based rayon fabrics as bio-based reinforcement material. Moreover, the development of a liquid thermoplastic resin has recently received attention due to its recyclability and its similar processing technology to thermosets.

Preliminary studies have shown that Elium resin has the potential to provide an innovative alternative to the use of epoxy-based resin systems. The aim of this project is to develop a new sustainable form of recyclable polymer composite produced from renewable resources, comprising the structural and flammability performances required for aircraft and train interior applications. The project results are to be exploited within the mass transport sector, where the cellulose fabric resin systems will be used to manufacture lightweight and flame-resistant composite face sheets for aircraft and train interiors. To ensure the achievement of the work, firstly, rayon fabric composites will be fabricated and characterised to evaluate their mechanical performance, thermal and damping behaviours. Process simulation of the bio-based composite plates will be performed. Secondly, flame retardant mats will be used to enhance fire resistivity of the bio-based composites in such a way to meet the flammability, heat release and smoke requirements. Thirdly, rayon fibres will be treated using commercial chemical agents to improve the fibre-matrix interfacial adhesion to lead to enhanced mechanical properties. Finally, simulation and prediction of rayon fabric Elium thermoplastic composite processing for the target interiors will be formulated.
