Abstract

Journal of Reinforced Plastics and Composites, Ahead of Print.
In this study, a numerical approach was adopted to optimize the geometric parameters of the patch and adhesive to improve the repair performance of a carbon/epoxy laminated composite structure. The studied laminate has a stacking sequence of [45/0/-45/90]...
