Abstract
8 pressure vessels of carbon fiber reinforced plastics (CFRP) have been manufactured with in the winding technology of same continuous carbon fiber–-amine system, new same flexible formula and same tension system. And the hydraulic bursting tests with the specimens were done in accordance with GB6058-85. The parameters of fiber strength, winding angle, geometric sizes and burst pressure were obtained by the tests. The theoretical analysis was done by conventional design method and reliability design method. The results show that: the theoretical calculating thickness of CFRP pressure vessel with by same parameters is thicker than practical thickness. This shows the performance of CFRP pressure vessel is related not only with fiber strength but also with material properties of resin matrix, tension and solidifying system of winding process. Because of CFRP (Carbon Fiber Reinforced Plastics) have many advantages which are high specific strength, high specific modulus, ablation resistance and low cost. Although the thing that composite materials have been substitutes for metal shell springs up soon, the application is much wide[1-6].
