Glass fibre / magnesium alloy composite material and preparation thereof

Abstract

The invention relates to a glass fiber and magnesium alloy composite and a preparation method thereof, which belong to the technical field of the composite and the preparation thereof, the composite is characterized in that the surface of the glass fiber is covered with magnesium alloy, the length of the glass fiber is 100 mm to 20000 mm, the mass ratio of the glass fiber and the magnesium alloy is 0.01 to 5, the glass fiber takes a shape of a bunch or knitting. The preparation method is as follows: the glass fiber after pretreatment is put into the magnesium alloy melt with temperature of 600 DEG C to 900 DEG C for 0.5 second to 60 seconds, so the glass fiber impregnated with the magnesium alloy is obtained; and the glass fiber and magnesium alloy composite can be obtained after the glass fiber impregnated with the magnesium alloy is cooled to room temperature, or the glass fiber and magnesium alloy composites profile can be obtained by press-processing the glass fiber impregnated with the magnesium alloy after cooling to 100 DEG C to 500 DEG C. The composite compound the continuous glass fiber and the magnesium alloy so that the plating magnesium alloy glass fiber composite and the glass fiber strengthening magnesium alloy composite profiles are obtained, thus opening up the new application of the glass fiber and the magnesium alloy.

Description

technical field [0001] The invention belongs to the technical field of composite materials and their preparation, and in particular relates to a glass fiber / magnesium alloy composite material and a preparation method thereof. Background technique [0002] Inorganic fiber / metal composites are an important member of the composite material family. With appropriate formulation and preparation process, the technical and economical complementarity and mutual promotion of inorganic fibers and metals can be realized: for metals, the introduction of inorganic fibers can improve their mechanical properties, heat resistance, wear resistance and other properties, and can Reduce material costs; for inorganic fibers, the introduction of metals can improve their mechanical properties and change their electromagnetic properties. [0003] Magnesium alloy is a light metal, and it is the lightest metal among the metal materials used on a large scale today. Magnesium alloy has a small specifi...
