采用压力浸渍和真空渗透的工艺制备了泡沫铜/聚酰亚胺互穿型复合材料，并重点研究了其作为滑动电接触材料的热稳定性，力学性能与摩擦磨损等方面性能。实验结果表明：该互穿型复合材料具备良好的耐热性，同时与不含泡沫铜的聚酰亚胺树脂基复合材料相比，其布氏硬度及抗弯强度等力学性能有一定的提高，滑动电接触性能从电压降的角度来说则有显著的改善。其次，研究发现该材料的磨损机制主要为疲劳磨损，同时伴随着轻微的磨粒磨损和氧化磨损。该材料在不同实验条件下都显示出较好的耐磨性，这表明泡沫铜与聚酰亚胺复合后的互穿型结构起了关键作用。
Polyimide matrix composites interpenetrated with foamed copper were prepared via pressure impregnation and vacuum immersion to focus on their thermostability, mechanical and tribological behaviors as sliding electrical contact materials. The results show that the interpenetrating phase composites (IPC) are very heat-resistant and exhibit higher hardness as well as bending strength, when compared with homologous polyimide matrix composites without foamed copper. Sliding electrical contact property of the materials is also remarkably improved, from the point of contact voltage drops. Moreover, it is believed that fatigue wear is the main mechanism involved, along with slight abrasive wear and oxidation wear. The better abrasive resistance of the IPC under different testing conditions was detected, which was mainly attributed to the successful hybrid of foamed copper and polyimide.
