In order to use the FW・RP cylinder as the structural member, it is necessary to evaluate the fatigue strength. Therefore, pulsating plane bending fatigue test were carried out with using FW・RP cylinders with several winding angles of fiber and several wall thickness. Major conclusions are summarized as follows : 1) The fatigue strength was higher at the lower winding angle fiber. Furthermore, it was observed that FW・RP cylinders with the lower and higher winding angle of fiber fractured on the compressive and tensile plane, respectively. These were explained from the load support ratio of the fiber. 2) The fatigue strength was higher in the larger wall thickness. This was dependent on the high flexural rigidity. 3) It was observed that the flexural rigidity decreased and the temperature rose during the fatigue test. The reduction of flexural rigidity resulted from the crack initiation and growth.
