Problems solved by technology

[0002] In the case of piston pins all made of steel material made of conventional SCM415 steel, the mileage cannot be improved due to its heavy weight when the piston pin is applied to a vehicle
In addition, in terms of the hoop direction bending strength and longitudinal bending strength required by the piston pin, the material properties of the conventional piston pin do not meet the requirements, so it is necessary to manufacture a piston pin to replace the conventional piston pin

Abstract

The invention discloses a composite material piston and a manufacture method for the same. The composite material piston comprises a tubular outer layer which is made of reinforced fibers, an inner layer which is connected to the outer layer along the inner surface of the outer layer, wherein the inner layer is made of reinforced fibers having elasticity lower than that of the outer layer, and a resin material. The resin material comprises an epoxy resin composition and cyanate ester and the resin material is permeated into the reinforced fibers of the outer layer and the inner layer.

Description

technical field [0001] The present invention generally relates to a composite piston pin. More particularly, the present invention relates to a piston pin of composite material made of multiple layers of tubular reinforcing fibers having different elasticity and a resin having a high glass transition temperature and good formability. Background technique [0002] In the case of a piston pin entirely composed of a steel material made of conventional SCM415 steel, when the piston pin is applied to a vehicle, the mileage cannot be improved due to its heavy weight. In addition, the material properties of conventional piston pins are not satisfactory in terms of hoop direction bending strength and longitudinal bending strength required for the piston pin, so it is necessary to manufacture a piston pin to replace the conventional piston pin. [0003] For this reason, the present invention aims at providing a composite piston pin made of carbon fibres, which is light and of good s...
