Abstract To investigate the influence of the angle of graphite on thermal conductivity and thermal expansion, the thermal properties of graphite reinforce Cu matrix composite was calculated with a simulation code which can take account of the angle of graphite at cross-section face. In this research, the orientation of graphite tends to be distributed parallel for the reason of the hot press during SPS process. Thermal conductivity of Cu matrix composite can be improved with the addition of graphite which has the improved orientation distribution. The result of the simulated thermal conductivity is as same as the measured thermal conductivity. Therefore, the simulation method mentioned in this article could be used for calculating thermal conductivity from cross-section figures of the composite which reinforced by a 2-dimensional material.

石墨取向分布对Cu基复合材料热导率的影响

摘要 为研究石墨夹角对热导率和热膨胀系数的影响，采用考虑截面表面石墨夹角的仿真程序计算了石墨增强铜基复合材料的热性能。在这项研究中，由于 SPS 过程中的热压，石墨的取向趋于平行分布。添加石墨可以改善Cu基复合材料的导热性，石墨具有改善的取向分布。模拟热导率的结果与实测热导率相同。因此，本文中提到的模拟方法可用于根据二维材料增强的复合材料的横截面图计算热导率。
