A carbon fiber reinforced thermoplastic (CFRTP) sheet was made by a plain-woven carbon fiber fabric and thermoplastic polyimide. Two types of the L-shaped CFRTP specimen were fabricated by hot-pressing of laminated sheet or hot-pressing of pre-consolidated laminated sheet. Wrinkle of fiber was not observed in the L-shaped CFRTP specimen by laminated sheet but observed in the specimen by pre-consolidated laminated sheet. Four-point bending tests on the L-shaped CFRTP specimens were performed and the interlaminar tensile strengths were calculated. The L-shaped CFRTP specimen by laminated sheet showed higher interlaminar tensile strength than the specimen by pre-consolidated laminated sheet. Small delamination parallel to the wrinkle was developed at the relatively low stress condition for the L-shaped CFRTP by pre-consolidated laminated sheet which degraded the interlaminar tensile strength.
