In this study, hybrid composites for a door impact beam were manufactured through a stacking sequence and design conditions. Non-crimped fabrics, epoxy resin for prepreg compression molding (PCM), hardener, and reinforcement such as p-Aramid and high strength polypropylene (PP) were used in manufacturing the hybrid composites. Curing behaviors of the PCM epoxy resin were confirmed by analytical methods such as dynamic DSC and FT-IR spectroscopy. The storage modulus, loss modulus, and damping behaviors of these hybrid composites were analyzed by dynamic mechanical analyses. Mechanical properties of the hybrid composites, such as tensile strength, flexure strength, compressive strength, and interlaminar shear strength (ILSS), were measured with a universal testing machine. Dynamic drop impact tests were conducted to measure the impact resistances of the hybrid composites on the stacking sequence. After the drop impact test, fracture shapes of the specimens were observed using a stereoscopic microscope. Based on the fracture shapes developed during the drop impact test, it was concluded that the specimens reinforced either by p-Aramid or PP effectively resisted impact transformations.
