Abstract: Copper coated short carbon fiber reinforced aluminum alloy matrix composites have been prepared with 0.3-1.5 wt% Mg as alloying addition by stir casting. Effect of Mg on the microstructure and mechanical properties of the composites was investigated. The microstructure was observed by scanning electron microscopy and the results show that adding Mg can make the distribution of carbon fibers uniform in the composites, reduce laminated and agglomerated. Tensile test and hardness test were carried out, the results show that the tensile strength and the hardness of the composite is increased by 13% and 8% when Mg content is 0.9 wt%.

Short carbon fiber reinforced AZ91 magnesium alloy matrix composites have been made by stir casting technique. The microstructure and the fibre matrix interfacial region of the composites characterized using optical and scanning electron microscopes reveal uniform distribution of fiber in the matrix and good interfacial bonding respectively. Increase in compressive strength values are observed with increase in fiber content where as the room and high temperature (150°C) strength properties are found to decrease marginally. The microfractograph of the tensile fractured surface reveals mixed type of fracture.
