摘要：

This article presents an experiment and simulation study on the tensile properties of Z-pinned composite laminates. Laminates of the lay-up patterns of unidirectional [0]6 and [90]12 and quasi-isotropic [45/0/-45/90]2S are studied by a test of monotonic tension. Simulation study is carried out by studying the microstructural unit cell through adjusting the first direction of the material coordinate systems of elements to model the deflexion of fibers around the Z-pin. The extent of the effect of the Z-pin on the tensile strength of the laminates is thus obtained by experiment and simulation. The study shows that in-plane fibre dilution and in-plane fibre deflexion and out-of-plane fibre crimping caused by Z-pin are the main causes for the decline in in-plane tensile properties of laminates. Furthermore, in-plane fibre deflexion is the main cause for the decline of in-plane tensile strength of laminates of the lay-up pattern of unidirectional [0]6, while in-plane fibre dilution is the main cause for the decline of in-plane tensile strength of laminates of the lay-up pattern of quasi-isotropic [45/0/-45/90]2S.
