Abstract

This paper presents the performance analysis of carbon composite materials with vacuum assisted resin infusion (VARI) method for electromagnetic interference shielding (EMIS) application. The structure was implemented using the VARI fabrication method and intended for shielding the synthetic aperture radar (SAR) instrument mounted on medium altitude long endurance (MALE) drone under development in Indonesian National Aerospace Agency. This structure is developed to shield and protect the radar subsystems from electromagnetic interference from other subsystems such as avionics and payload systems. The S-parameters measurements have been done in the anechoic chamber using vector network analyzer (VNA). The shielding effectiveness of the material is evaluated over 0.9 GHz and 5.3 GHz frequency bands using S11 for reflection factors and S21 for transmission factors to investigate the material characteristics. All of the material has fluctuated value. The quite stable value in 0.8–1 GHz S21 (dB) was carbon twill vinyl.

电磁干扰条件下碳复合材料VARI性能分析

本文介绍了真空辅助树脂注入法(VARI)用于电磁干扰屏蔽(EMIS)的碳复合材料性能分析。该结构采用VARI制造方法实现，旨在屏蔽安装在印度尼西亚国家航空航天局正在开发的中高空长航时(MALE)无人机上的合成孔径雷达(SAR)仪器。这种结构被开发用来屏蔽和保护雷达子系统免受来自其他子系统如航空电子设备和有效载荷系统的电磁干扰。利用矢量网络分析仪(VNA)在消声室中进行了s参数测量。以S11为反射因子，S21为传输因子，分别在0.9 GHz和5.3 GHz频段对材料的屏蔽效能进行了评估。所有的材料都有波动的价值。在0.8-1 GHz的S21 (dB)范围内，碳斜纹布乙烯基是比较稳定的值。
