| 中文摘要: |
| 应用ANSYS软件对聚合物/中空微球复合材料单元中的热传递进行了有限元分析，并计算出中空微球填充NR复合材料的等效导热系数ke值。结果表明，ke随着中空微球体积分数φf的增大呈线性减小，且随着微球粒径的增大有所减小。此外，三维有限元模拟的ke值高于二维，两者的差异随着φf的增大而增大。 |
| 英文摘要: |
| A finite element analysis(FEA) of the heat transfer in NR/hollow bead composite was made and the equivalent thermal conductivity(ke) was calculated.The results showed that ke decreased linearly with the increase of the bead volume fraction φf and decreased somewhat with the increase of the bead particle size.Furthermore，ke from the 3D FE simulation was higher than that from 2D FE simulation，and the difference between them increased with the increase of φf. |
