| 中文摘要: |
| 基于Ansys Workbench 稳态热分析模块，针对颗粒形状、填充体积分数、圆柱体颗粒取向及长径比等填充情况，对复合材料的导热性能进行模拟研究。结果表明，复合材料的热导率随颗粒填充体积分数的增大而增大，填充圆柱体颗粒复合材料的热导率大于填充球形等颗粒复合材料，圆柱体颗粒取向变化对复合材料导热性能的影响明显，而且其热导率随长径比的增大而增大。 |
| 英文摘要: |
| Based on the Ansys Workbench steady state thermal analysis module，the thermal conductivity of rubber composites filled with particulates was simulated and the effects of the shape of particulates，volume fraction of loading，orientation and aspect ratio of fillers were studied.The results showed that the thermal conductivity increased with the increase of the volume fraction of particulates and the shape of the filler particles had great influence on the thermal conductivity.The thermal conductivity of composites filled with cylindrical particles was higher than that of composites filled with spherical particles，and the thermal conductivity increased with the increase of the aspect ratio of the cylindrical particles.Moreover，the orientation of cylindrical particles also influenced the thermal conductivity significantly. |
