Title:
COMPOSITE BODY
Document Type and Number:
Japanese Patent JP2020122082
Kind Code:
A
Abstract:
To provide a composite body as an adhesive agent capable of exhibiting sufficient adhesion strength by releasing stress after adhering dissimilar materials each other.SOLUTION: A composite body 1 comprises a laminate structure in which a first thin layer 2 comprising an epoxy resin is sandwiched by a second thin layer 3a and a third thin layer 3b comprising a phenol resin and a nitrile rubber so as to take the surfaces of the second layer and the third layer as adhesion surfaces. In the composite body, a surface direction maximum elongation of the first layer after being hardened is smaller than surface direction maximum elongations of the second layer and the third layer. As a result of this, an adhesive agent having stress relieve and high adhesion strength can be obtained and used for bonding dissimilar materials such as metals and plastics.SELECTED DRAWING: Figure 1
