Abstract

Carbon fiber reinforced polymer (CFRP) composites have occupied more important position for excellent mechanical properties, which are limited by brittle failure under loads meanwhile. For this reason, recent researches are mainly focused on improving non-linear behaviour of CFRP. This non-linear behaviour can be thought as a pseudo-ductile response. This paper proposes a three-dimensional (3-D) mesoscale model for the finite element analysis of nonlinear stress–strain responses of CFRP angle-ply [±] 2s and cross angle-ply ([/-/(90+ /(90- ]s laminates. One ply of the laminate model contains three fiber layers. Fiber orientation varies from 15ºto 45ºfor angle-ply laminates and varies from from 10ºto 35ºfor cross angle-ply laminates, respectively. Predictions of the nonlinear stress-strain responses of various angle-ply agree well with previous experimental results, which verifies that the present mesoscale model is available for the prediction of the pseudo-ductile behaviour of angle-ply laminates. Cross angle-ply laminates give about 50% lower pseudo-ductile strain than that of angle-ply laminates. Large fiber orientation angle yields high pseudo-ductile strain for both of angle-ply and cross angle-ply laminates.
