In this paper, to determine the impact of carbon fiber orientation and interweaving on electromagnetic interference (EMI) shielding behaviors, anisotropic and isotropic samples were developed by conductive/dielectric weaving of spatially distributed carbon fiber and glass fiber. Effortless and cost-effective, the electromagnetic shielding efficiency (SE) was up to 42 dB and the SE/thickness) was 41 dB/mm, which had apparent polarization selection characteristics. In addition, the angle (θ) sensitivity for the SE in transverse electric and transverse magnetic polarization modes was given in detail. SE was generally proportional to θ. Moreover, the fingerprint-like radar chart of anisotropic carbon hybrid woven fabrics in the X-band was performed, which makes polarization selection characteristics more intuitive. This paper presented an easy and effective route for assembling hybrid carbon fiber fabrics with high EMI shielding performance, which offers a clear perspective on the simulation and study of carbon fiber electromagnetic properties.

在本文中，为了确定碳纤维取向和交织对电磁干扰 (EMI) 屏蔽行为的影响，通过空间分布的碳纤维和玻璃纤维的导电/介电编织开发了各向异性和各向同性样品。电磁屏蔽效率 (SE) 高达 42 dB，SE/厚度) 为 41 dB/mm，具有明显的极化选择特性，轻松且经济高效。此外，还详细给出了横向电极化和横向磁极化模式中 SE 的角度 (θ) 灵敏度。SE 通常与 θ 成正比。此外，还进行了X波段各向异性碳混纺织物的指纹式雷达图，使得偏振选择特性更加直观。
