摘要
测试了碳纤维复合材料层合板的有关电磁参数。数据表明 ,随着电场方向与纤维方向夹角的增大 ,材料的ε′r 值增大而tgδe 值减小 ,铺层呈现极大的各向异性 ;然后 ,应用时域有限差分法 (FDTD法 )分析了复合材料整体电磁特性。
The electromagnetic parameters concerning of the laminate of carbon fiber composite (CFRP) bave been detected. The result of the experiment has indicated that with the angle between electric field and fiber orientation increasing, the dielectric constant ε′ r and loss angle tangent tgδ e decreasing, the laminate strongly shows maximum anisotropy. The whole electromagnetic properties of composite have then been analyzed by the finite difference time domain imitation method.
