In order to increase the burst strength of CFRP pressure vessels, their hoop stress should be reduced under an internal pressure. This paper presents a method how to increase the burst strength of CFRP pressure vessels. The shape memory alloy (SMA) wire memorized a compressive stress is wound around the surface of CFRP pressure vessels. When the CFRP pressure vessels is received the internal pressure, its hoop stress can be reduced by the memorized compressive stress of SMA wire and then the burst strength can be increased. The experimental results were compared with numerical ones and they agreed well each other. Furthermore, Optimum design of the CFRP pressure vessels by the change of winding pattern of SMA wire was numerically obtained and then the relationship between burst pressure and winding pattern of SMA wire was shown.
