The working group for structural use of FRP in JSAE (FRP W/G), has been considering the possibility of applying FRP in use of a crush box of a car. Compressing the vertical plane of the FRP laminate structure, a destruction of stable crack growth between layers, and rupture of the fiber occurs continuously. This mode is called "progressive crushing", and considered to be an ideal energy absorbing form. The objective of this study is to observe the phenomenon of the initial micro-fracture of the trigger part of FRP crush box, and analyze the transition process of initial micro-fracture to the progressive crushing. The authors have observed the phenomenon of initial rupture process, the cracks due to the delamination from compression inside the crush box, and the cracks occurred outside the crush box. Also the rupture of the fibers was observed by X-ray CT scanner.
