英文摘要: Metal-reinforced carbon fiber composites were made with T700 carbon fiber, epoxy resin, cooper mesh, nickel mesh, permalloy as raw materials, in order to get the excellent product, the selected optimal molding process was utilization; before these process, metal-reinforced materials should be pretreated so as to improve the bonding properties between it with epoxy resin. In addition, interlayer bonding properties, electrical properties and electromagnetic shielding properties were detected, and the results show: the interlayer bonding properties of the metal-reinforced carbon fiber composites prepared by this method were excellent, and the electrical continuity of metal-reinforced materials were not destroyed after putting it into the carbon fiber composite material. The shielding...
中文摘要: 以T700碳纤维为增强材料,环氧树脂为基体材料,铜网、镍网、坡莫合金为电磁屏蔽增强材料,采用选定的最优成型工艺制作了金属强化碳纤维复合材料,为了改善金属强化材料与树脂的结合性能,在使用前需对其进行预处理。研究了该材料的层间结合性能、电性能和电磁屏蔽性能,结果表明:通过本方法制得的金属强化碳纤维复合材料具有良好的层间结合性能,未发生分层、开裂现象,并且将金属强化材料加入碳纤维复合材料未破坏其原有的电连续性,通过屏蔽性能测试发现通过改变金属材料的导电(导磁)能力,可以提高复合材料在各频段的电磁屏蔽性能,在低频下尤为明显。
