Abstract

Off-axis plies have a great influence on the tensile failure stress of carbon fiber reinforced polymer (CFRP) multidirectional laminate. Matrix cracks in the off-axis plies will cause negative effect on the layers, leading to fatal failure of the laminate. A microscale cohesive zone model is proposed to explore the influence of matrix cracks in the off-axis plies on the tensile failure of [0/θ]ns laminates. Simulations of tensile failure of [0/θ]s laminate were performed by varying the off-axis ply angle θ ranging from 15° to 90° and the cohesive properties to investigate the effects of off-axis plies to the failure of the laminates. Tensile tests of [0/θ]2s laminates with various off-axis ply angles were conducted to validate the simulations of microscale model. The simulation results with matrix cracking are in high agreement with the experimental results, illustrating the influence of off-axis plies on the tensile failure of [0/θ]ns laminates.
