The microstructure and the fracture morphologies of the composites were observed, and the tensile properties of composites were characterized. Results show that the yield strength (YS) and ultimate tensile strength (UTS) of CF-HEAp/Al composites are firstly increased and subsequently decreased with increasing the CFs content from 0vol% to 40vol%, while the elongation is decreased. Owing to the hybrid reinforcing effects of Ni-Co-P coated carbon fibers and FeCoCrNiAl high-entropy alloy particles, the YS and UTS of CF-HEAp/Al composites have larger improvement compared with those of CF/Al and HEAp/Al composites, and the fracture morphology is characterized by mixed rupture modes of ductile rupture of 7075Al matrix and fiber pull-out and fracture."/>
