1 cfrp * ** ** CF R P( CF RTP ) CF RP CF RP : Study on Press Forming Method of Carbon Fiber Reinforced Thermoplastics Sheet Mitsuhiko TAKA, Takashi KONDA and Yorihiro YAMASHITA In order to establish the mass production of carbon fiber reinforced thermoplastics (CFRTP) parts using press forming method, it is necessary to develop the forming die and press machine control techniques for CFRTP.

2 So, it is necessary to clarify the relation press conditions with properties of sheet and quality of mold parts. In this study, we investigated the influence of various conditions in forming process for the quality such as the formability, strength, surface and shape conditions of molding parts by temperature measurement of sheet in pre-heating , and deep drawing test.
