对石蜡填充纳米碳纤维复合材料的热性能进行了实验研究和理论分析。测量了纳米复合材料在凝固过程中的瞬态温度响应，并预测了冷却速率。结果发现，纳米复合材料的热导率显着增强，导致冷却速率增加。基于一维热传导方法建立了一个分析模型，预测了新型纳米复合材料的有效导热系数，其结果与实验数据吻合较好。同时，对比研究了碳纳米纤维表面特性对石蜡热性能的影响。(C)2005爱思唯尔有限公司保留所有权利。
Thermal performance of nanocomposite carbon nanofibers filled paraffin wax was studied experimentally and analytically. The transient temperature response of made nanocomposite was measured during its solidification process and the cooling rate was predicted. It was found that nanocomposite thermal conductivities were enhanced significantly causing the cooling rate to increase. An analytical model was introduced based on one-dimensional heat conduction approach to predict the effective thermal conductivity for the new nanocomposites and its findings showed good agreement with the experimental data. Also, a comparative study was performed to investigate the effect of carbon nanofibers surface characteristics on thermal performance of paraffin wax. (C) 2005 Elsevier Ltd. All rights reserved.
