Description

technical field [0001] The invention relates to the field of composite materials, in particular to a method for preparing carbon nanotube-reinforced aluminum-based composite materials. Background technique [0002] Composite materials refer to materials formed by combining two or more phases of materials together. Most of the composite materials widely used in modern times are composed of various high-performance fibers as the reinforcing phase and resin as the matrix phase. Aluminum matrix composites have high specific strength, specific modulus, good electrical and thermal conductivity, and high temperature performance. They have been applied in aerospace, automotive, and microelectronics fields and have attracted more and more attention. Carbon nanotubes have a unique structure and excellent physical and chemical properties (the Young's modulus can reach 1-1.8TPa, the tensile strength can reach 150GPa, and the density can reach 1.2-1.8g / cm 3 , the thermal expansion coef...
