Adhesion technology has become more importance as a joining technology of resins or metal to resin. Because of this circumstance, IHI is developing adhesion technology. From the point of view of design and fabrication, this article outlines adhesion technologies, such as adhesives, adhesion fabrication and mechanical characteristics of joint, and introduces application and study examples of adhesion technology in IHI.
