چکیده انگلیسی
2D carbon fiber reinforced AZ91D matrix composites (2D-Cf/AZ91D composites) were fabricated by liquid-solid extrusion and vacuum pressure infiltration technique (LSEVI). In order to modify the interface between fibers and matrix and protect the fiber, pyrolytic carbon (PyC) coating was deposited on the surface of T700 carbon fiber by chemical vapor deposition (CVD). Microstructure observation of the composites revealed that the composites were well fabricated by LSEVI. The segregation of aluminum at fiber surface led to the formation of Mg17Al12 precipitates at the interface. The aluminum improved the infiltration of the alloy and PyC coating protected the fibers effectively. The ultimate tensile strength of 2D-Cf/AZ91D composites was about 400Â MPa. The fracture process of 2D-Cf/AZ91D composites was transverse fiber interface cracking-matrix transferring load-longitudinal fibers bearing load-longitudinal fibers breaking.
