Description

technical field [0001] The invention relates to a preparation method of a micron and nanometer fiber hybrid reinforced aluminum matrix composite material. Background technique [0002] Due to the different properties of various reinforcing materials, hybrid composite materials complement each other, especially due to the hybrid effect, which will obviously improve or improve some properties of the original single reinforcing material, and at the same time greatly reduce the raw material cost of composite materials. Aluminum matrix composites are the most concerned type of materials among metal matrix composites. There are many preparation methods for hybrid aluminum matrix composites, including powder metallurgy, in-situ reaction composite method, squeeze casting method, low pressure infiltration method, stirring method, etc. It has been reported that hybrid reinforced aluminum matrix composites are superior to single reinforced composites in room temperature mechanical prop...
