| 摘 要： | 为评价带有金属内衬的复合材料构件固化工艺制度，采用有限元方法对其进行二维温度场和固化度场的分布模拟。在模型中通过有限差分法考虑了温度与固化度的耦合作用，建立了带有金属内衬的复合材料构件固化工艺数学模型。数值计算结果表明：复合材料的厚度可以加剧构件的固化速率及温度梯度；金属内衬在固化过程中更像一个吸热器，起到减缓温度梯度和固化速率的作用。计算结果与实验数据符合较好，验证了模型数值结果的可靠性。

| Abstract: | To evaluate cure cycle of composite component with internal metallic mold,finite element method was employed in numerical simulation of its two-dimension temperature and cure degree field distribution in this paper.Mathematical model was established to describe cure process of composite component with internal metallic mold during filament winding process,and the coupling between temperature and cure degree was considered using finite difference method in the model.Numerical results show that the thickness of composite component affects the rate of cure and temperature gradient.Internal metallic mold plays a role in a heat-sink,which slows up the gradient of temperature and the rate of cure.Compared with experimental data,the reliability of the model established in this paper was proved. |
