碳-铝复合材料的显微组织与其工艺过程有密切联系。因此,通过分析研究其显微组织特征,可以发现工艺过程中存在的问题,为进一步正确选择工艺参数,改善工艺过程。提高纤维及复合材料的性能提供参考。本文介绍了用金相及扫描电子显微镜拍摄的,在各工艺条件下的碳纤维、镀镍碳纤维、真空热处理镀镍碳纤维、碳-铝复合丝以及碳-铝热压试样的显微组织。 The microstructure of carbon-aluminum composites is closely related to its process. Therefore, by analyzing the characteristics of the microstructure, we can find out the problems existing in the process, in order to further correctly select the process parameters and improve the process. Improve the performance of fiber and composite materials provide a reference. In this paper, the microstructures of carbon fiber, nickel-plated carbon fiber, vacuum heat-treated nickel-plated carbon fiber, carbon-aluminum composite wire and carbon-aluminum hot pressed sample taken by metallographic and scanning electron microscope are introduced.
