Abstract

The invention discloses a preparation method of preparing an inorganic fullerene enhanced aluminum-based nano composite material and belongs to the field of synthesis of nano materials. By taking aluminum powder and inorganic fullerene nanoparticles as raw materials, inorganic fullerene and the aluminum powder are uniformly mixed by means of the ultrasonic technique, and the inorganic fullerene and the aluminum powder are mixed and pressed and sprayed to a certain shape by means of the 3D printing technique. In the inorganic fullerene enhanced aluminum-based composite material, the inorganic fullerene in an aluminum base has good dispersibility, and an aluminum matrix has regular grain sizes. By means of the 3D printing technique, more sample shapes can be designed. The composite nano material has an impact resistant principle different from that of other impact resistant materials and better impact resistance. The composite nano material has good application prospects in the fields ofsafety of automobiles, high-speed trains and airplanes, light shock absorbing materials and the like.

Description

technical field [0001] The invention relates to the field of nanomaterial synthesis, in particular to a method for preparing inorganic fullerene-reinforced aluminum-based nanocomposites. Background technique [0002] Aluminum is a silver-white light metal with ductility, and its products are often made into rods, flakes, foils, powders, ribbons, and filaments. The content of aluminum in the earth's crust is second only to oxygen and silicon, and it is the most abundant metal element in the earth's crust. my country has extremely rich aluminum ore. Aluminum and its aluminum alloys are currently one of the most widely used and most economical materials. Aluminum has a melting point of 660°C and a boiling point of 2327°C. Aluminum's light weight and corrosion resistance are two outstanding features of its performance. The density of aluminum is very small, only 2.7g / cm 3 , Space rockets, space shuttles, and artificial satellites also use large amounts of aluminum and its al...
