摘要： 本文对碳纤维缠绕复合材料压力容器进行了非测地线缠绕线型设计、有限元仿真和纤维缠绕与水压爆破实验。根据非测地轨迹确定了复合材料压力容器的最佳缠绕参数;采用有限元软件ABAQUS对其受压状态下的应力应变值进行分析,研究内压为35 MPa时压力容器的应力状态,并预测其爆破强度为92.2 MPa;缠绕实验在五轴数控缠绕机上进行,使用T800碳纤维制备了铝合金内衬复合材料压力容器,其纤维缠绕层共26层,缠绕完成后纤维排列整齐均匀,无滑纱现象。固化后其爆破压强为87.5 MPa,与仿真结果相对误差为5.1%,验证了仿真分析的可行性。

Abstract: In this paper, non-geodesic winding linear design, finite element simulation and filament winding and hydraulic blasting experiments were carried out on carbon fiber wound composite pressure vessels. The optimal winding parameters of the composite pressure vessel were determined according to the non-geodesical trajectory. Validity of the trajectory was verified as well, the stress and strain values under pressure were analyzed by finite element software ABAQUS. The stress state of the pressure vessel at 35 MPa internal pressure was studied, and its blasting was predicted. The strength is 92.2 MPa. The winding experiment is carried out on a five-axis CNC winding machine. The T800 carbon fiber wound aluminum alloy inner liner is used to complete the development of the composite pressure vessel. The fiber winding layer has 26 layers, and the fibers are arranged neatly and evenly after winding without slippage phenomenon. After curing, the blasting strength is 87.5 MPa, the actual value differs from the predicted value by 5.1%, and the feasibility numerical analysis was verified. In conclusion the present analysis result of both numerical and experimental were in good agreement. Meanwhile, the manufacture foundation for the preparation of eminent performance and prominent specification filament wound products was laid.
