Embodiment 1

[0020] 1) Firstly, the punching rhombic carbon steel mesh is molded to form the pyramid core 1, the pyramid core 1 and the panel 2 are cleaned to remove oil and rust, and then the pyramid structure core 1 and the panel 2 are connected by brazing. Pyramid structure lattice metal sandwich panels, see figure 1 ;

[0021] 2) Secondly, use scotch tape to seal the three sides of the pyramid sandwich structure, and place the unencapsulated side up under the clamp to keep it vertically placed;

[0022] 3) Then, at room temperature, mix the epoxy resin-based damping material and the curing agent amino-terminated polyether in a mass ratio of 1:1 to obtain a slurry;

[0023] 4) Finally, pour the slurry into the core hole 3, and let it stand at room temperature for 2 to 3 days to solidify, and obtain a pyramid-structured lattice metal sandwich panel filled with epoxy resin-based damping materials, see figure 2 . Among them, the relative density of the pyramid lattice core is 1-10%, an...

Abstract

Disclosed is a preparation method of pyramidal lattice metal and epoxy resin matrix damping composite structure. Pyramidal lattice metal material and epoxy resin matrix damping material are cast and composited to obtain lightweight isolation vibration material. The pyramidal lattice metal and epoxy resin matrix damping composite sandwich plate is widely applicable to the mechanical manufacture and military fields and has the advantages of effectively lowered structural weight, improved damping characteristic and improved vibration damping performance.

Description

technical field [0001] The invention relates to a preparation method of a pyramid structure lattice metal interlayer board, in particular to a pyramid lattice metal-epoxy resin base damping composite structure and a preparation method thereof. Background technique [0002] Ultralight porous metal materials are a class of novel multifunctional materials that have emerged with the rapid development of material preparation and machining technology in recent years. Its core has high porosity, and its microstructure can be divided into disordered and ordered according to the degree of regularity. The former includes closed-cell aluminum foam materials, while the latter includes two-dimensional lattice materials (such as corrugated structures) and three-dimensional trusses. Structure (such as pyramid structure, tetrahedron structure). [0003] At present, as a metal composite material, the lattice sandwich structure has inherent defects in vibration reduction because of its own s...
