碳纳米管/聚合物复合材料层合结构的横波传播

The Transverse Wave Propagation in Carbon Nanotubes/Polymer Composites Laminated Structures

通过多层弹性梁模型研究了碳纳米管/聚合物复合材料层合结构在高频率(1 TH z左右)下的横波传播,分析了碳纳米管的体积分数和手性对其传播的影响.结果表明,考虑聚合物基体为小尺寸时,除通常意义下的临界频率外,还有另一特殊频率,同时有一震荡区域存在,这一点与考虑基体为无穷大的情况有所不同.

The transverse wave propagation in carbon nanotubes/polymer composites laminated structures under ultrahigh frequency（about 1THz）was studied based on the multiple-elastic-beam model. Effects of the volume ratio and chiral vectors of carbon nanotubes on transverse wave propagation were analyzed. The results show that besides the generally critical frequency, there is another especial critical frequency where an oscillation zone appears when the polymer matrix is considered as small scale, which is different from the case of infinite polymer matrix presented in literature.
