Abstract: Disclosed herein is a method of treating a composite piston pin, including: preparing the piston pin of which at least surface layer includes a composite material including a reinforcing fiber and a resin; improving roughness by processing the surface layer of the piston pin; and forming a coating layer on the surface layer processed to reduce a friction coefficient of the piston pin.
