Authors performed to repair carbon fiber reinforced thermoplastics (CFRTP) with delamination caused by impact, assuming the condition that heat and pressure could be applied to the specimen from only one side of actual CFRTP structure. For damage repair, a heated spherical indenter was pressed against the damaged specimen from one side to close and bond delamination in the specimen. For shape repair, the specimen regained its original flat shape since specimen deformed into the shape of the indenter. In addition, the validity of the repair method was evaluated through comparison of the flexural modulus in the four-point bending test. As a result, delamination was reduced in damage repair and the flexural modulus of specimen after repair was restored by about 14.3% compared with that after impact, despite the small delamination that occurred in the specimen due to shape repair.
