The explosion characteristics of a composition pressure vessel comprised of three kinds of different CFRP layer of the winding angle are examined. A location of the fracture origin is identified using fractographic technique from the length of the piece of the CFRP in the burst vessel. Also the fracture initiation location of the container is estimated using the time lag at the time of the arrival of the elastic wave by the high-speed strain measurement of CFRP at the burst.
