摘要: The high performance fiber-reinforced plastics have hierarchical reinforcement architectures. They exhibit complex failure processes that occur interactively and concurrently on multiple scales are closely linked to the constituents’ behavior architecture. chapter describes different stages of damage development their link structural levels. At micro-level onset is influenced by microscopic morphology inside fiber bundles submicroscopic organization nano-reinforcements. latter introduce strong inhomogeneity in stress fields change concentrations at fiber/matrix interface. transition from debonding intra- inter-ply then discussed focusing differences between laminates with unidirectional textile plies. experimentally observed phenomenology supported findings simulation studies.
