Abstract:
An object of the present invention is to provide a prepreg and a laminate for producing a laminate suitable as a structural material, which have excellent compressive strength and interlaminar fractural toughness values, and can be firmly integrated with another structural member by welding. The present invention provides a prepreg including the following structural components [A] reinforcing fibers, [B] a thermosetting resin, and [C] a thermoplastic resin, in which [B] has a rubbery state elastic modulus of 10 MPa or more at a temperature obtained by adding 50° C. to a glass transition temperature in a state in which a degree of cure is 90% or more, [C] is present in a surface of the prepreg, and the reinforcing fibers [A] are present, which are included in a resin area including {B] and a resin area including [C] across an interface between the two resin areas.
