Effect of gap and overlap fiber placement defects on the delamination behavior of L-shaped composite laminates

This paper concerns the automated fiber placement (AFP) induced gaps and overlaps over the course of laying quasi-isotropic curved laminates. The failure of the curved composite components is generally dominated by interfacial delamination due to the relatively low out-of-plane properties of the laminates. Within this study, the effects of the gaps and overlaps on the out-of-plane tensile strength of the laminates with multidirectional plies...
