摘要
考察了玻璃纤维三维夹芯层连织物/氰酸酯（CE）复合材料的透波性能,并与夹芯层连织物/环氧树脂复合材料和蜂窝夹层结构复合材料进行了对比。研究发现：实验频段范围内三维夹芯层连织物/氰酸酯复合材料的平均透波率高于蜂窝夹层结构复合材料和夹芯层连织物/环氧树脂复合材料;夹芯层连织物/氰酸酯复合材料的透波率受电磁波入射角度影响较小,并且在芯柱高度为8 mm时有最大值,平行经向入射的透波率略大于平行纬向入射的透波率,8-12 GHz频率的透波率略大于12-18 GHz的透波率;由于反射作用,面板增强后夹芯层连织物/氰酸酯复合材料的透波率下降明显。
The wave transmission property of the three-dimensional（3D） glass fiber spacer fabric/cyanate ester（CE） composite was investigated by comparison with the 3D spacer fabric/epoxy composite and the honeycomb sandwich composite.The results indicate that the 3D spacer fabric/CE composite shows better wave transmission property than that of both the spacer fabric/epoxy composite and the honeycomb sandwich composite.Moreover,the wave input angle has little influence on the wave transmission property of the 3D spacer fabric/CE composite,and the spacer fabric/CE composite reveals highest wave transmission property with the pile height of 8 mm.When the wave transmits parallel to the warp direction larger transmission property can be observed than that along the weft direction.And the wave transmission property in the range of 8~12 GHz is better than that of 12~18 GHz.Besides,the facesheet reinforcement decreases the wave transmission property due to the wave reflection.
