摘要
自紧处理能有效提高复合材料气瓶的疲劳性能和纤维利用率。以容积为140L、工作压力为35.0MPa的全缠绕复合材料气瓶为例,对其自紧压力优化方法进行研究,并采用有限元法对全缠绕复合材料气瓶进行自紧分析。结果表明:同时借助DOT-CFFC和ISO-11119标准可实现34.5MPa以上的全缠绕复合材料气瓶自紧压力的优化;经过最佳自紧压力处理后,35.0MPa全缠绕复合材料气瓶在工作载荷工况下内衬的承载能力和复合材料层的纤维利用率分别提高了42.1%和38.7%。
Self-tight operation can effectively improve composite cylinder＇ s anti-fatigue performance and car- bon fiber utilization. Taking fully-wrapped composite cylinder with 140L volume and 35.0MPa operating pres- sure as an example, the method of optimizing self-tight pressure was investigated, including adopting the finite element method to analyze the cylinder＇ s self-tight operation. The results demonstrate that both DOT-CFFC and ISO-11119 standards can implement this self-tight optimization of the cylinder with over 34.5MPa working pressure ; and after it, the liner＇ s bearing capacity of this 35.0MPa fully-wrapped composite cylinder and the fiber utilization can be increased by 42.1% and 38.7% respectively under the working pressure.
