Preparation method of foamed aluminum structural part and foamed aluminum structural part

Abstract

The invention relates to the technical field of materials, in particular to a preparation method of a foamed aluminum structural part and the foamed aluminum structural part. The preparation method comprises the following steps of carrying out surface treatment on a foamed aluminum matrix; preparing a rubber sizing material according to a set size; wrapping the surface of the foamed aluminum matrix with the rubber sizing material, and putting the foamed aluminum matrix into a vulcanization mold; closing the mold, and discharging gas on the joint face of the foamed aluminum matrix and the rubber sizing material; carrying out vulcanization molding on the rubber sizing material at the designed temperature, pressure and time, and forming a coated rubber layer on the surface of the foamed aluminum matrix; and opening the mold after the vulcanization time is up to obtain the foamed aluminum structural part. According to the preparation method of the foamed aluminum structural part, the surface of the foamed aluminum matrix is coated with the rubber layer through the vulcanization process, the structural part is provided with the rubber surface, no disintegrating slag falls off, the man-machine environment is improved, and meanwhile the shock resistance of the foamed aluminum structural part can be improved through the rubber layer.

Description

technical field

[0001] The invention relates to the field of material technology, in particular to a method for preparing a foamed aluminum structural part and the foamed aluminum structural part. Background technique

[0002] Porous metal foam material is a new type of engineering material with dual properties of function and structure, including steel, aluminum, nickel and other matrix materials, among which aluminum foam is widely developed and used. As a structural material, aluminum foam has the characteristics of light weight and high specific strength; as a functional material, it has various physical properties such as porous, vibration reduction, damping, sound absorption, sound insulation, heat dissipation, impact energy absorption, and electromagnetic shielding. Compared with solid structural materials, aluminum foam has a certain degree of compressibility and can absorb impact energy. Therefore, aluminum foam is a kind of impact-resistant material with great app...
