Problems solved by technology
[0006] However, the method of manufacturing a dissimilar material joint body by using a separate adhesive takes a long time to harden the adhesive, so there is a problem that the process efficiency is lowered, and the total thickness of the dissimilar material joint body increases, so it is difficult to sufficiently ensure adhesiveness
[0007] In addition, a method of applying heat alone such as insert molding has a problem that the material on one side is denatured by heat

Abstract
The present invention relates to a method of manufacturing a joined body of dissimilar materials, the method comprising: a step of forming an etching line on a surface of a glass layer by irradiating laser light; and providing a resin layer on the glass layer on which the etching line is formed, and then A step of joining the resin layer and the glass layer by irradiating with laser light.
Description
technical field [0001] This specification claims priority and benefit from Korean Patent Application No. 10-2017-0132736 filed in the Korean Intellectual Property Office on October 12, 2017, the entire contents of which are incorporated herein by reference. [0002] The present invention relates to a method of manufacturing a joint body of dissimilar materials. Background technique [0003] Various researches for joining dissimilar materials having different material properties and fixing the two materials, especially researches for improving the joining force of glass and plastic materials, are continuously being conducted. [0004] In addition, in order to ensure the durability of the dissimilar material joint body used as a cover part of various devices, etc., and to easily mass-produce the dissimilar material joint body by simplifying the manufacturing process and reducing the time taken for the manufacturing process of the dissimilar material joint body, Research on me...
