碳纤维复合材料高压球形容器研制

Development of High Pressure Spherical Vessel of Carbon Fiber Composites

采用变带距方法对球形容器进行优化设计 ,并研制了一批产品。试验结果表明 ,在纤维设计应力相同条件下 ,采用变带距缠绕的球形容器 ,其复合材料重量比等带距缠绕的轻 2 4 .6% ,而其容器特性系数高出 1 0 .4 % ,能同时满足设计提出的强度和重量两方面要求。

In this paper,optimum design of spherical vessel using varable bandwidth method and a batch of products are presented.The experimental results show that,with the same designed stress of fiber the weight of spherical vessels fabricated with variable bandwidth is 24.6% lower than those with constant bandwidth,while their performance factor of vessel is 10.4% higher than those with constant bandwidth. It dicates that the design can meet with the designer's requirements both in strength and weight.
