Improving the performance of pseudo-ductile hybrid composites by film-interleaving

Improvement of the interfacial fracture toughness layer interfaces is one way to increase performance interlayer hybrid laminates containing standard thickness carbon/epoxy plies and make them fail in a stable, progressive way. The were interleaved with thermoset 913 type epoxy or thermoplastic acrylonitrile–butadienestyrene (ABS) films introduce beneficial energy absorption mechanisms promote fragmentation relatively thick carbon under tensile loads. Carbon dispersed delamination around fractures characterised damage modes film laminates, which showed pseudo-ductility some cases. In ABS unique phase-separated ABS/epoxy inter-locking structure was discovered at boundary two resin systems, resulted strong adhesion between fibre-reinforced layers. As result, cracks contained within interleaf films.
