Abstract: The objective of this study is to evaluate strain-rate- and temperature- dependent characteristics of carbon fiber reinforced thermoplastic composites (CFRTP). In this study, we performed 3-point bending impact test of CFRTP using high speed impact testing machine controlled by hydraulic actuation, which is equipped with thermostatic chamber. The test conditions of strain-rate were ranging from 0.01 /s to 10 /s in each temperature environment of -30, 0, 25, 50, 75 and 100 ℃. In addition, the dynamic fracture behaviors were observed by using a high speed video camera. As a result of the impact test, it was confirmed that CFRTP has strain-rate and temperature dependence of the flexural strength. And, the fracture mode in each strain-rate and temperature condition was clarified from the high-speed images. As a result, it was confirmed that the fracture mode also changed by strain-rate and temperature conditions.
