Particle reinforced aluminum matrix composite reflector and preparation method thereof

The invention belongs to the technical field of aluminum-based composite materials, and relates to a particle reinforced aluminum-based composite material reflector and a preparation method thereof, a reflector substrate is prepared by a semi-solid stirring casting-extrusion composite one-time forming method, and the particle reinforced aluminum-based composite material reflector of which the elastic modulus is greatly improved is obtained by a subsequent processing technology. Compared with a powder metallurgy method for preparing the silicon carbide aluminum matrix composite reflecting mirror, the particle reinforced aluminum matrix composite reflecting mirror is simple in preparation process and low in cost, the density of the particle reinforced aluminum matrix composite reflecting mirror is smaller than or equal to 2.80 g/cm < 3 >, the elasticity modulus is larger than or equal to 85 GPa, and the density is larger than or equal to 99%. 本发明属于铝基复合材料技术领域，涉及一种颗粒增强铝基复合材料反射镜及其制备方法，采用半固态搅拌铸-挤复合一次成形法制备反射镜基体，并经后续
