In the literature, studies have shown that lamina thickness have a significant effect on the mechanical response and damage propensity in the structure. In this study, quasi-static in-plane compression experiments coupled with digital image correlation (DIC) were performed on a carbon-fiber reinforced composite with three different thicknesses of 2, 3, and 4 mm. The thickness increased with an increase in the nth ply of 90° while keeping number of 0 plies constant in all the laminates. A LS-Dyna based finite element model (FEM) was developed using a progressive damage model (MAT_55) to predict the mechanical response of the composite. The results demonstrated that reducing the 90° lamina thickness can influence the mechanism of damage propagation and significantly alter matrix failure. Overall, this study provides insights towards the design and optimization of composite laminate for impact resistance in structural application. © 2024 The Authors. Published by ELSEVIER B.V.
