Abstract: In this study, two types of fibers, carbon and E-glass, and two types of polymers, engineering polymer, polyamide 6, PA6, and high-performance polymer, polyphenylene sulfide, PPS, were selected to investigate the effect of matrix and reinforcing fiber on the impact resistance of continuous fiber reinforced thermoplastic (CFRTP) composites. Quasi-isotropic samples of, CF/PPS, GF/PPS, CF/PA6, and GF/PA6 were fabricated and subjected to drop weight impact at energy levels of 10 J/mm, 15 J/mm, and 20 J/mm. Impact resistance mechanisms depended on the type of fiber and matrix, for example, ductile fiber improves impact resistance of brittle matrix and stiff fiber improves the impact resistance of soft and ductile thermoplastic matrix. The type of damage depended on the matrix material, and despite higher indentation and puncture of the PA6 composites, they retained higher compressive strength after impact.
