摘要: To provide a metal-fiber reinforced plastic composite material which exhibits favorable impregnation of a matrix resin into a reinforcing fiber substrate and favorable adhesion to metal members, and excellent mechanical properties. The metal-fiber reinforced plastic composite material is a laminate of a metal member and a fiber reinforced plastic, wherein the fiber reinforced plastic includes a reinforcing fiber substrate (A) and a thermoplastic resin composition (B), the thermoplastic resin composition (B) contains a phenoxy resin (B-1) and a polyamide resin (B-2) at a mass ratio (B-1)/(B-2) of 80/20 to 20/80, an adhesive strength of the thermoplastic resin composition (B) to a monofilament of the reinforcing fiber substrate (A) is 40 MPa or more as an interfacial shear strength at 23° C. in a microdroplet method, and an adhesive strength between the metal member and the thermoplastic resin composition (B) is 7.0 MPa or more as a tensile shear strength at 23° C.

摘要: Provided is a thermoplastic resin composition which has excellent heat resistance, mechanical characteristics, and adhesion properties with respect to a reinforcing fiber base material, which is a different kind of material, and from which a molded article particularly having excellent rigidity at a high temperature is obtained. A thermoplastic resin composition is provided, which includes: a phenoxy resin (A) having a hydroxy group and/or an epoxy group at a polymer chain terminal; and a polyamide resin (B), wherein a proportion of the phenoxy resin (A) is 50 to 90 mass % and a proportion of the polyamide resin (B) is 10 to 50 mass % relative to a total amount of 100 mass % of the phenoxy resin (A) and the polyamide resin (B), and a tensile modulus retention rate [Equation (i) below] of a dumbbell test piece (JIS K 7139, Type A1), and a molded article manufactured therefrom is also provided.

摘要: According to the present invention, a surface of a prepreg (104), said surface being provided with a partially fused structure (102A), and a surface of a metal member (110) are brought into contact with each other, and heat and pressure are subsequently applied thereto. After completely melting a resin containing a thermoplastic resin and adhering to the prepreg (104) so that a reinforcing fiber substrate (101) is impregnated with the molten resin, the resin is cured to obtain a matrix resin (105), thereby forming a CFRP layer (120) that serves as a fiber-reinforced resin material, and the CFRP layer is simultaneously compression-bonded to the metal member (110), so that a metal-CFRP composite body (100) in which the CFRP layer (120) and the metal member (110) are firmly bonded to each other is formed.
