COMPOSITE MOLDING AND PRODUCTION METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a production method of a composite molding that can raise bond strength.SOLUTION: A production method of a composite molding includes: a process in which when a laser beam is irradiated to a joint area of a metal molding 10 to form a pore group, a laser beam is irradiated so that a depth of a pore formed by 1 scan may become 10-200 μm, a pore in which a cross-sectional shape is a triangle or a shape having approximation with the same is formed, thereby a projection group consisting of burr is formed on a surface of a periphery of an apertural area of the pore group; and a process in which a part including a joint area of the metal molding 10 in which the pore group and the projection group are formed is arranged in a mold to perform insert molding with resin becoming a resin molding 20.
