Abstract—This study deals with damage investigation on KFRP/CFRP composite laminates subjected to low-velocity impact using a drop-weight impact test. The three variations of composite laminates including KFRP, CFRP and KFRP-CFRP composite laminates were tested. The results from KFRP and CFRP composite laminates were used to estimate the fracture energy of each material for KFRP-CFRP composite simulation. The goal is to model the complicated failure surface of KFRP-CFRP composite laminates using damage evolution models and also cohesive elements for interfacial failure between different composites. A good agreement with experimental results was found.
