摘要: 主要讨论辅助材料层和空气层流对复合材料固化温度场的影响。采用有限元方法求解温度-化学耦合场和流-固体传热场,具体数值分析了透气毡的厚度、密度,空气层流的厚度,以及风压对固化温度、固化度、固化速率的作用。结果表明,辅助材料层不论其密度还是厚度,都影响很小,而层流厚度及风压会引起固化温度滞后与超越,同时热压罐风压或者风速可以调制树脂的固化速率。

关键词: 空气层流, 有限元, 温度场, 固化度

Abstract: This paper mainly focuses on curing temperature field of composite materials with auxiliary material layer and forced convection. Using finite element method, the solutions of temperature-chemical coupling field and fluid-solid heat transfer field are obtained. Especially, the effects of the thickness, density of breath cloth, thickness and wind pressure of laminar air flow on curing temperature, curing degree and curing rate are analyzed numerically.The results show that the density and thickness of auxiliary material layer have little effect on curing field. The laminar thickness and the wind pressure will cause the curing temperature lag and overstep and the curing rate of the resin can be modulated by wind pressure or wind speed in autoclave.

Key words: air laminar flow, finite element, temperature field, curing degree
