* Metallic matrix composite outline what why how application 1 2 3 4 2 * people’ desires are higher and higher. especially in the aspect of structure material, it is not only required high strength material, but also ask for it more light in weight. Metallic matrix composite is born for those requirements. overview What ? Metallic matrix composite combines metal or alloy matrix with fiber, whisker and particles to enhance the material’ properties. * why--- comparining  strength and stiffness the traditional metal materials excellent electrical conductivity and heat resistance resin matrix composites high toughness and high impact performance ceramic base material * Why---Properties ◎ Specific strength and specific modulus ◎ good Heat conduction ◎ Small thermal expansion ratio and good dimensional stability ◎ Good high temperature performance * * How--The main process method ※Liquid state processing ※Powder metallurgy composite ※Spray co-deposition ※Casting solidification forming * Application Use in the aerospace, the future will occupy the important position in the field of aeronautics and astronautics. Use in the automotive, sporting goods and other fields has been applied …… * * * Thanks!
