摘要： 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. In the case where the coating layer consists of two layers, the first coating layer that is located on the metal member side is a coating layer containing an isocyanate group, and the second coating layer that is located on the CFRP layer side is a coating layer that contains an epoxy resin as a main component thereof, and has bonds represented in (a structural formula 1) in the vicinity of an interface between the first coating layer and the second coating layer.-

摘要： This adhesively joined structure includes a first member having a metal portion and a film portion disposed on at least a part of a surface of the metal portion; a second member; an adhesive layer for joining the first member and the second member to each other via the film portion. The film portion includes an organic resin phase containing one or more of a urethane group, an epoxy group, and an ester group; an organic compound phase formed of an organic silicon compound; and optionally an inorganic compound phase formed of an inorganic silicon compound. The total volume percentage of the organic compound phase and the inorganic compound phase to the total volume of the film portion is 16 vol% to 84 vol%. The volume percentage of the organic compound phase to the total volume of the film portion is 16 vol% to 84 vol%. The volume percentage of the inorganic compound phase to the total volume of the film portion is limited to 10 vol% or less. The organic silicon compound includes a Si-C bond; and a Si-O bond or a Si-OH bond or a a combination thereof.

摘要： The invention has as its object the provision of a metal-fiber reinforced plastic composite able to more reliably prevent occurrence of an electrolytic corrosion action when forming a composite of a metal member and a fiber reinforced plastic layer comprising reinforcing fiber (carbon fiber) and a matrix resin.
A metal-fiber reinforced plastic composite 1 according to the present invention comprises a metal member 10, an insulating layer 30 arranged on at least part of a surface of the metal member 10 and comprising a first matrix resin 31 containing nonconductive fiber 32, and a CFRP layer 40 arranged on at least part of a surface of the insulating layer 30 and comprising a second matrix resin 41 containing carbon fiber 42, wherein, when viewing the surface of the metal member 10 from vertically above, the CFRP layer 40 is positioned at the inside of a region where the insulating layer 30 is present and an outer edge of the CFRP layer 40 and an outer edge of the insulating layer 30 are 0.2 mm or more apart. Due to this, it is possible to prevent electrolytic corrosion of the metal member.-
