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f 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f 的增大而增大。 A finite element analysis(FEA) of the heat transfer in NR/hollow bead composite was made and the equivalent thermal conductivity(k_e) was calculated.The results showed that k_e decreased linearly with the increase of the bead volume fraction _f and decreased somewhat with the increase of the bead particle size.Furthermore,k_e from the 3D FE simulation was higher than that from 2D FE simulation,and the difference between them increased with the increase of _f.
