摘要

摘要: 基于固化反应动力学、热传导和复合材料层合理论, 采用了有限元分析方法, 对具有金属内衬的复合材料纤维缠绕压力容器在固化工艺过程中的温度和热应力分布及其变化规律进行了数值模拟。通过一典型容器数值分析, 表明在固化工艺过程中, 中容器内部的所有应力分量具有同时达到峰值的特征, 其中应力分量的峰值出现在固化降温阶段的初期。提出了数值模拟的方法和分析结论对复合材料结构设计师和工艺师合理制订金属内衬复合材料纤维缠绕容器的工艺标准具有一定的参考价值。

Abstract: The curing process of the filament wound pressure vessel with metal liner is simulated. A methodologyis proposed for predicting the evolution of the dist ributions of temperature and process-induced st ress fields duringthe whole curing process. Based on cure kinetic , t ransit heat conductive and composite laminated st ress analysis theories , the corresponding formulas of the finite element method are briefly int roduced. A typical numerical example ispresented to illust rate it . The result s show that the temperature and process-induced thermo-st ress fields involvecomplex variations during the curing process , and the peak values for all st ress component s tend to occur simultaneously at the beginning cooling down stage , whose magnitudes are related to the variations of the temperature in theautoclave during the curing process. The numerical simulation method and conclusions could be of great value to engineers of the composite st ructures.
