Abstract

This study proposes a two-scale approach to determining the effective thermal conductivity of fibrous composite materials. The analysis was first carried out at the fiber-interphase level to calculate the effective thermal conductivity of this system, and next at the whole composite structure level. At both scales, the system behavior was analyzed using the finite element method. To determine the effective thermal conductivity for the fiber-interphase system, an inverse problem was solved, while a simple unidirectional heat conduction test was performed for the entire composite. The simulations were carried out for typical fibrous composites: carbon fibers-epoxy resin and glass fibers-epoxy resin. The results showed a significant impact of realistically observed interphase thicknesses on the heat conduction properties of the tested composites.

摘要

本研究提出了一种双尺度方法来确定纤维复合材料的有效热导率。首先在纤维-界面水平上进行分析，以计算该系统的有效热导率，然后在整个复合材料结构水平上进行分析。在两个尺度上，均使用有限元方法对系统行为进行分析。为了确定纤维-界面系统的有效热导率，求解了一个反问题，而对整个复合材料进行了简单的单向热传导测试。针对典型的纤维复合材料：碳纤维-环氧树脂和玻璃纤维-环氧树脂进行了模拟。结果表明，实际观察到的界面厚度对测试复合材料的热传导性能有显著影响。
