• 摘要： 对于环境苛刻的电磁兼容环境下，常用电磁屏蔽材料已不能满足对设 备及相关系统的保护作用，如高低温或强酸碱的特殊工作环境等，本文通过对 比几种金属参数，并将 Ti 金属与其他性能优良的金属结合制备出高效能电磁屏 蔽复合材料，利用法兰同轴测量电磁屏蔽效能法测得含 Ti 金属合金电磁屏蔽复 合材料的电磁屏蔽效能在工作带宽 7—15GHz 下平均可达 85dB。
• For the harsh environment of EMC, the common electromagnetic shielding materials can not meet the protection of equipment and related systems, such as the special working environment of high and low temperature or strong acid and alkali, this paper compares several metal parameters, and introduces Ti High efficiency electromagnetic shielding composite materials were prepared by combining metal and other metals with excellent performance. The electromagnetic shielding effectiveness of the composite materials containing Ti metal alloy was measured by the method of coaxial flange measurement. The average electromagnetic shielding effectiveness of the composite materials can reach 85 dB under the working bandwidth of 7-15 GHz.
