摘要

An investigation of the through-thickness properties of carbon fibre prepreg laminates, Non-Crimp Fabric laminates and non-crimp 3D orthogonal woven composites by pull-through testing was performed. Influence of matrix system and curing temperature on the performance of the 3D woven composites was investigated.The results showed that the prepreg specimens endured the highest pull-though loads, followed by the 3D woven composites, and the NCFs. It was found however that the prepreg laminates were characterized by the largest extent of damage after the test, whereas only very localized damage was present in the 3D woven composites. The NCF specimens presented overall the worst bolt pull-thought performance. No significant influence of the matrix system and curing temperature on the 3D woven composites' performance was observed.
