Regulation of carbon fiber reinforced plastic (CFRP) properties and failure mode upon low-velocity impact by hybridization of the reinforcing fibers is discussed. Effect of the ratio of carbon fiber (CF) and plasma-activated ultra-high molecular weight polyethylene (UHMWPE) fiber contained in a hybrid fiber on the ultimate tensile strength and impact properties et al. properties of the hybrid composite material (HCM) has been investigated by impact break (IB) method. It was found out that at the ratio of CF:UHMWPE-fiber = 20:80, the carbon and UHMWPE-fibers in HCM are no longer deformed and broken down simultaneously. At first carbon and then UHMWPE-fiber are broken down. At this ratio the HCM values of ultimate tensile strength and specific absorbed-in-fracture energy were increased by the factors of 1.65 (from 594 to 986 MPa) and 1.98 (from 47 to 89 J/cm 2 ), respectively. The detected effect of the delay in the destruction of HCM can be used to create aircraft and other impact-resistant structures.
