A kind of three-dimensional skeleton structure metal reinforced aluminum matrix composite material and preparation method |
| abstract |
The invention relates to a metal matrix composite material, in particular to a three-dimensional skeleton structure metal reinforced aluminum matrix composite material and a preparation method. The composite material is composed of a reinforcement prefabricated block with a three-dimensional skeleton structure and an aluminum matrix, and the reinforcement is in the aluminum matrix. The volume fraction in the composite material is 30%-70%; it includes the following steps: S1: preparing a reinforcing body preform by additive manufacturing technology; S2: melting the aluminum matrix in a protective atmosphere to obtain a metal aluminum melt; S3: adding reinforcement After the prefabricated block is preheated and kept warm, it is placed in the press together with the mold, the metal aluminum melt is poured into the mold, the temperature of the press table is controlled, and pressure infiltration is carried out; S4: After the pressure is released, it is naturally cooled to room temperature to obtain Three-dimensional skeleton structure metal-reinforced aluminum matrix composites. Compared with the prior art, the present invention can improve the thermal conductivity of the aluminum-based composite material under the condition of obviously improving the strength and modulus of the composite material, thereby realizing the improvement of the comprehensive performance of the aluminum-based composite material. |
