| 摘 要： | 热固性复合材料构件应用广泛，但其在加热固化成型过程中易产生变形。通过优化铺层设计，可以减小碳纤维增强环氧树脂细长杆件固化过程的变形，但是忽略了截面形式对固化变形的影响程度。本文提出在复合材料大长径比构件设计时应采用有限元分析(Finite element analysis, FEA)方法进行热变形分析，充分考虑截面对称性对产品固化变形的影响，有效降低该类产品固化过程中的变形。

| Abstract: | Thermoset resin has a wide range of applications in composites structures. Meanwhile, the deformation during the heat curing process brings high trouble to structural profile accuracy. In order to control the deformation of carbon fiber reinforced resin composites during curing process, the layup design is optimized to improve the structural strength and stiffness. Whereas the process-induced deformation caused by section has more effects on the acerose CFRP pipe. In this paper, the finite element analysis(FEA) is used to for thermal deformation analysis of large aspect ratio composite components. The effect of cross-section symmetry on the curing deformation of products should be fully considered to effectively reduce the deformation in the curing process of such products. |
