Research Abstract |
In this study, a type of adhesive that can be separated on demand has been developed for material recycling of adherends bonded by adhesion. The adhesive includes thermally expandable microcapsules(TEMs) as blowing agent, which induces internal force and leads to the fracture of the interfaces in high temperature. For the purpose, the matrix resin of the adhesive, which is epoxy resin, was examined in terms of modulus, strength, and viscoelastic properties. The expansion characteristics of TEMs were also measured experimentally. In addition, stress distribution in the joint boded by the adhesive was calculated by finite element analysis.
