SiCp/Al composites have excellent properties and are widely used in advanced aerospace equipment. However, due to the great difference in physical and mechanical properties between SiC particles and aluminum alloy, it is easy to be damaged in the process of processing, which seriously affects the accuracy and service performance of SiCp/Al composites products and restricts its engineering application. This paper focuses on the low damage processing technology of SiCp/Al composites, analyzes the related research progress at home and abroad from three aspects: the formation mechanism of processing damage, the influencing factors of processing damage, low damage processing tools and low damage processing technology, summarizes the current research status and shortcomings of low damage processing technology for SiCp/Al composites, and brings forward the development trend and direction.
