摘要: 本文分别使用有限元分析法和试验法研究了双轴向经编织物增强树脂泡沫夹层结构复合材料的导热行为,分析了织物结构、边界条件、材料属性等因素对复合材料热传导性能的影响。通过有限元方法分析了夹层结构复合材料的热传导行为,发现各组分材料导热性能的差异和温度梯度方向均会影响夹层结构复合材料的导热行为,且后者影响作用更明显。通过红外热成像试验测试了夹层结构复合材料的热传导过程、温度分布和最终热平衡时的温度,试验结果与有限元方法得到的结果具有一致性。

Abstract: In this paper, the thermal conductivity behavior of biaxial warp knitted fabric reinforced resin foam sandwich composite was studied by finite element method and experimental method respectively, and the effects of fabric structure, boundary conditions and material properties on the thermal conductivity of the composite were analyzed. The heat conduction behavior of sandwich composite was analyzed by finite element method. It was found that the difference of thermal conductivity of each component and the direction of temperature gradient both affected the thermal conductivity behavior of sandwich composite, and the latter effect was more obvious. The heat conduction pro-cess, temperature distribution and final heat equilibrium temperature of sandwich composite were measured by infrared thermal imaging test, and the results are consistent with those obtained by finite element method.

Key words: sandwich composite, finite element method, heat conduction, thermal conductivity
