Abstract
The present invention provides a method of adhering adherends, including (i) providing at least two adherends at least one of which is made of a flexible material, and (ii) joining the adherends together to form a structure using a heat-resistant adhesive composition containing mainly 1) a polycarbodiimide resin and an epoxy resin, or 2) a polycarbodiimide resin, an epoxy resin and a curing agent for the polycarbodiimide resin, or 3) a polycarbodiimide resin, an epoxy resin and a curing agent for the epoxy resin. The heat-resistant adhesive composition can be applied under mild conditions, and the resultant structure has excellent heat resistance and chemical resistance, and has superior adhesion strength particularly at high temperatures.
