Research and Proposal on Surface Texture Parameters for The Injection Molded Direct Joining Using Micro Blasting

Abstract

Solving environmental problems and energy problems is global urgent task. Weight saving of transportation equipment and robot is one of the effective solutions. The direct joining of metal and resin using a blasted surface is effective for weight saving. The problem is that the parameters of JIS/ISO standard have insufficient correlation with the shear strength of the direct joining of metal and resin using a blasted surface. In this paper, new surface roughness parameters that considered various geometrical characteristics of surface texture are proposed. And, proposed parameters are confirmed that have higher correlation with the shear strength than the parameters of JIS/ISO standard.
