TITANIUM OR TITANIUM ALLOY, ADHESIVE RESIN COMPOSITION, PREPREG AND COMPOSITE MATERIAL

摘要

The present invention relates to a composite material using titanium or a titanium alloy, and concerns such a composite material obtained through processes in which after an imidazole compound has been applied to the surface of titanium or a titanium alloy, an adhered is adhered thereto. The composite material of the present invention is obtained by adhering the adhere thereto by using an adhesive resin composition containing a thermoplastic resin having a fracture energy release rate G1C of 4500 J/m2 or more. The present invention makes it possible to provide a composite material using titanium or a titanium alloy, which exerts a superior adhesive strength stably at room temperature as well as even after exposure to a high-temperature, high humidity condition.
