Abstract

See full text

Provided is a press forming method for a composite material, which prevents a longitudinal section of the composite material from being exposed to outside. To this end, the method includes: cutting edges of the upper metal layer and the resin layer using a cutter such that the resin layer is cut relatively more than the upper metal layer; bending the upper metal layer toward the lower metal layer; and folding the lower metal layer by an angle of 180 degrees using a hemming die such that side surfaces of the upper metal layer and the resin layer are prevented from being exposed to outside.
