In this paper, Ni-coated carbon fiber was prepared by electroplating process, and continuous carbon fiber reinforced Al matrix (Cf/Al) composite plate was successfully prepared via twin-roll casting and short process forming process, and the effect of pouring temperature on the microstructure, interface characteristics, fracture morphology and mechanical properties of the Cf/Al composites was investigated. The results indicate that the Cf/Al composite plate with smooth and no obvious surface defects were fabricated under the conditions of pouring temperature of 963-983K, rolling speed of 2.7m/min and roll gap of 2.0mm; Among them, when the pouring temperature is 973K, the interface between the carbon fiber and the Al-matrix is ??well bonded; Ni-coated on the surface of fiber significantly improves the wettability between carbon fiber and aluminum matrix, and also effectively inhibits the formation of Al4C3 brittle phase, which greatly improves the mechanical properties of Cf/Al composite strip. The tensile strength of the Cf/Al composite plate at a pouring temperature of 973K increased by 87.4% compared with the initial 38.2MPa.
