? 2022 Elsevier B.V.In the present study, a novel method for manufacturing functionally graded metal matrix composites (FGMMC) is introduced. This method is a cutting-edge combined plastic deformation process of accumulative roll bonding (ARB) and cold roll bonding (CRB) and was used to fabricate Al/Cu functionally graded composites. Several laminated composites with different content of Cu were first fabricated by the ARB process, then they were bonded by the CRB process as the volume fraction of Cu varies from the Al side to the Cu side. With an increase in Cu content, the hardness of layers rose. Furthermore, the SEM images showed the continuous changes of Cu content from the Al side to the Cu side of the composites. In addition, based on the results of the tensile test, since Cu layers act as reinforcements in the Al matrix, the strengths gradually grew with the progressive increase in the volume fractions of Cu.
