Abstract
A theoretical model has been developed to investigate the effects of through-thickness pinning (z-pin) on mode I delamination. Computer simulation results are presented to understand the mechanism of z-pin reinforcement. Bridging force of the z-pin is calculated by a single pin pull-out model. Numerical results of the fracture load versus mode I delamination crack growth are obtained. Effects of the areal density, radius and Young’s modulus of z-pin are also studied. By assuming different interfacial friction coefficient, the effect of pin/laminates friction is discussed.
