The deep drawability of carbon fiber reinforced thermoplastic laminates was evaluated. Deep drawing was performed on the twill weave laminates by changing the mold temperature. When the mold temperature was 160°C, large wrinkles were observed on the specimens and fiber breakage occurred. In the case of 210°C, deep drawability was good and no fiber breakage was observed. From the load-displacement diagram during molding, that the load required for molding decreased with increasing temperature during molding. Deep drawing was also performed on laminates with various laminate configurations. In the woven laminate, the flange area deformed significantly. As a result, large wrinkles occurred. The generated wrinkles spread to the dome section and affected the formability of the dome section. In the quasi-isotropic laminate, wrinkles were dispersed throughout the laminate and the generation of large wrinkles was suppressed. The shape of the dome section was better molded in the quasi-isotropic laminate.
