Abstract: Advanced polymer textile composites are characterised with high strength to weight ratio and tailored mechanical properties claiming their applications in advanced engineering sectors. The research work presented is focused on the development and characterisation of compressive behaviour of monolithic Kevlar and carbon-Kevlar hybrid fabric reinforced polymer composites (FRPCs). Vacuum-assisted resin transfer moulding process is used to cast the composite laminates. Results obtained present the effect of hybridisation of carbon yarns with Kevlar fabric, also compare the compression modulus and compressive strength of two fabrics along longitudinal axes. Fabrics with different weaving patterns, namely plain and twill are considered for reinforcement to experimentally investigate the role of weaving pattern plays in governing the mechanical strength of textile composite. FE model is generated to numerically simulate the compression loading behaviour of composites. Simulation results of longitudinal compression of carbon-Kevlar hybrid fabric composite show a good agreement with experimental results.

Keywords: compression behaviour; vacuum-assisted resin transfer moulding; polymer textile composites.
