Experimental Study of Temperature Dependent Thermal Contact Resistance of Individual Carbon Fibers

Keywords： Raman spectrometer , effective thermal conductivity , laser absorptivity , thermal conductivity , thermal contact resistance

由于微纳米材料特征尺寸小,难以测量其与热沉间的接触热阻.本文利用拉曼光谱测量不同温度下单根PAN基碳纤维的热导率及其与导电银胶、焊锡和硅油间的接触热阻.结果表明,在实验温度范围内其热导率随温度的降低而增大;接触热阻随温度的变化规律与接触物质有关.
