摘要

2D carbon fiber reinforced Mg-Al-RE matrix composites (2D-C_f/AE44 composites) were fabricated by liquid-solid extrusion following vacuum pressure infiltration technique (LSEVI). Pyrolytic carbon (PyC) coating was deposited on surface of T700 carbon fiber by chemically vapour deposited (CVD) to modify the interface. TEM observation of the composites revealed that particle shaped Al₂RE and lamellar shaped Al₁₁RE₃ precipitated at the interface. The precipitation of Al-RE phase inhibited the formation of Mg-Al phase and the PyC coating protected the fiber effectively. SEM observation of fracture surface, as well as TEM analysis of the interface, were employed to explain the inherent relation between interface behavior and mechanical properties of 2D-C_f/AE44 composites.
