The present invention in part by replacing some components of constituting the powertrain may be directed to a method of manufacturing a drive plate assembly, using the carbon fiber composite material, more particularly a vehicle drive plate assembly to the light weight and the carbon fiber composite material of high strength to improve the fuel consumption by weight reduction is one of the manufacturing method of the vehicle drive plate assembly to cope with regulation of fuel consumption forced car.
The present invention includes the steps of cutting to correspond to the shape of the drive plate to a plurality of the carbon fiber composite material by using a cutting press die; Placing the stacked plurality of cutting the carbon fiber composite material with a predetermined angle interval by at least one; A step of laminating the plurality of the carbon fiber composite material formed by hot pressing a hot press mold to form a drive plate of the plate-like semi-finished product; Refining the external shape by cutting and polishing the molding step the semi-finished product; Step of the semi-finished trimming the outer shape punching with a bolt hole for engagement with the engine to complete the drive plate; And a method of manufacturing using carbon fiber, characterized in that the composite material consisting of a drive plate assembly to a technical aspect; and completed the drive plate to the ring gear and the fastening to the step of completing the manufacture of the drive plate assembly.
