PREFORM, SHEET MATERIAL, AND COMPOSITE SHEET MATERIAL

摘要

Provided are a preform, a sheet material and an integrated sheet material which have excellent fabricability at the time of fabrication, and which has an excellent balance of impact resistance property and rigidity in a molded article obtained after fabrication. This preform is characterized in that (A) and (B) are laminated. (A) A self-reinforced sheet which is reinforced with a thermoplastic resin (a-1), and a fiber or tape (a-2) which is composed of a thermoplastic resin which is the same type as the thermoplastic resin (a-1). (B) A reinforced sheet which is reinforced with a random mat (b-1) which is composed of a discontinuous carbon fiber, and a thermoplastic resin (b-2).
