摘要

Metal matrix composite (MMC) sheets with well-dispersed reinforcements can be continuously produced using the accumulative roll-bonding (ARB) method. However, carbon fibers (CFs), an ideal reinforcement for MMCs, have not been extensively utilized due to the poor wettability of carbon/aluminum system. This study addresses this issue by modifying the fiber surface with copper (Cu) coating and applying this new reinforcement to Aluminum matrix composites (AMCs) produced via the ARB method. The results demonstrate that copper coated CFs (Cu-CFs) were well-dispersed throughout the matrix with appropriate ARB cycles. The surface treatment improved the spatial uniformity of the reinforcement, enhanced interfacial bonding, and refined the matrix grains. Consequently, the Cu-CF/Al composites exhibited the highest tensile strength (187.8 MPa) compared to composites reinforced with uncoated CFs (131.9 MPa) and monolithic Al without CFs (122.7 MPa). These findings suggest that combining ARB with electroless copper coating holds broad prospects in materials engineering, providing a valuable area of study for enhancing composite material performance.
