摘要： 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.

摘要： A hybrid piston pin and a manufacturing method thereof are provided. The hybrid piston pin includes a cylindrical pin formed of steel, a first reinforcement layer that is formed of a composite that includes reinforced fibers and a resin, having a cylindrical shape with a uniform thickness, and coupled to the interior surface of the cylindrical pin. A second reinforcement layer is formed of a composite that includes reinforced fibers having an elasticity that is less than the reinforced fibers of the first reinforcement layer. Further, a resin having a cylindrical shape with a uniform thickness is coupled to the interior surface of the first reinforcement layer.
