Abstract

The effect of angle and thickness of plies are investigated on the fracture energy release rate (ERR) in mode II of carbon/epoxy prepreg laminated composites using finite element modelling. The ply’s angle of = 0o, 22.5o, 30o, 45o, 60o, and 90o with 4 different thicknesses are investigated. The finite element modelling is done using the virtual crack closure technique (VCCT) to evaluate the asymmetric effect. The overall stiffness of the laminates is designed to have the least difference from the Mode II standard ASTM test. The results show that by increasing the thickness of the plies, the asymmetric effect and consequently the mode I/Mode II loading contribution is increased. The results show that ERR is decreased by increasing both angle and thickness of the plies. This understanding can help in designing composite materials with better delamination resistant properties under different loadings such as low-velocity impact.
