Abstract:
A laminated body, containing a fiber-reinforced resin, in which a fiber-reinforced thermoplastic resin layer (1) containing fiber bundle of reinforcing fibers and a first thermoplastic resin, and a resin layer (2) containing a second thermoplastic resin, are alternately laminated, to form the fiber-reinforced resin, and the ratio of the indentation elastic modulus EIT-B of the first thermoplastic resin portion of the laminated body with respect to the indentation elastic modulus EIT-C of the second thermoplastic resin is 1.5 or more and 5.0 or less; a fiber-reinforced composite resin material; and a method of producing these.
