摘要: 基于参比样品法原理,创新设计了一套材料有效热导率测量装置,并深入评估了其工作稳定性。首先利用碳纤维毡验证测量装置的稳定性,然后测试不锈钢、铜及石墨在不同条件下的热导率,并与理论值进行了对比分析,最后针对碳纤维毡材料,系统研究了温度、环境气氛及树脂含量对其热导率的影响。结果表明:该装置在0~700 ℃区间对不锈钢与铜材料的热导率测量准确性较高,但不适用于石墨材料;随温度与树脂含量上升,碳纤维毡的热导率显著提升,为材料热性能优化提供了重要参考。

Abstract: Based on the principle of reference sample method, a set of measuring device for material effective thermal conductivity is designed and its working stability is evaluated. Firstly, carbon fiber felt was used to verify the stability of the measuring device, and then the thermal conductivity of stainless steel, copper and graphite under different conditions was tested and compared with the theoretical value. Finally, the influence of temperature, ambient atmosphere and resin content on the thermal conductivity of carbon fiber felt was systematically studied. The results show that the measurement accuracy of the thermal conductivity of stainless steel and copper is high in the range of 0-700 ℃, but it is not suitable for graphite. With the increase of temperature and resin content, the thermal conductivity of carbon fiber felt increases significantly, which provides an important reference for the optimization of thermal properties of materials.

Key words: vacuum carbon tube furnace, reference sample method, effective thermal conductivity, vacuum atmosphere
