In　this　paper,　the　fabrication　methods　of　magnesium　matrix　composites　were　introduced　and　the　new　fabrication　process　was　emphasized.　The　effects　of　the　fabrication　processes　on　the　composition,　structure　and　properties　of　the　composites　were　analyzed.　Developing　new　reinforcements　and　novel　in-situ　reaction　synthesis,　optimizing　the　fabrication　process　and　preparing　high　performance　composites　on　larger　scale　are　main　research　keys　to　the　magnesium　matrix　composites.
