  • Publication number: 20210114350
    Abstract: To provide a metal-carbon fiber reinforced plastic material (CFRP) composite that has excellent adhesion and adhesion durability at a member interface and a method of producing a metal-CFRP composite. The metal-CFRP composite according to the present invention includes: a metal member; a CFRP layer; and one or two layers of coating layers provided between the metal member and the CFRP layer. In the case where the coating layer consists of one layer, the coating layer is a coating layer containing an isocyanate group, and the matrix resin contains a phenoxy resin as a main component thereof, contains an epoxy group, and has bonds represented in (a structural formula 1) in the vicinity of an interface between the CFRP layer and the coating layer.
