Keywords： Carbon fibre

Four kinds of Mg alloys reinforced with carbon fibres were fabricated by a gas pressure infiltration technique.The fibres were pre-coated a SiO2 layer prior to fabrication.Different microstructures and interactions in the fibre-matrix interface of these composites were observed by transmission electron microscopy (TEM).The results showed that the interracial interaction strongly depended on the content of Al in the Mg-based matrices.The microstructure of the interface could then be controlled by adjusting the Al content of the Mg-based matrix.In addition,fibres extracted from different Mg-based matrix all had some degradation owing to the interracial reaction and the fibre-matrix interdiffusion.
