Graphene possesses special properties different from traditional materials,such as excellent mechanical properties and thermal conductivity.It has attracted extensive attention since it was discovered.One of the important applications is to strengthen metal matrix materials as reinforcement to obtain high-performance structural and functional composites.In recent years,in order to meet the needs of composite with optimized and complex structure,higher requirements have been put forward for its manufacturing method.Selective laser melting(SLM)is a kind of additive manufacturing technology,which avoids the shortcomings of high cost,long cycle and low precision of traditional manufacturing technology,and can more flexibly realize the function-structure-material integration.This paper summarizes the application research and development status of graphene reinforced metal matrix composites(aluminum,nickel,titanium,iron,copper)prepared by SLM.In addition,the main problems in graphene reinforced metal matrix composites were discussed.Moreover,we look forward to the application and development prospects of graphene reinforced metal matrix composites.
