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
The present invention relates to a kind of preparation method of pyramid structure dot matrix metal sandwich plate, be specifically related to a kind of pyramid dot matrix metal-epoxy resin base damping composite construction and preparation method thereof.
Background technology
The ultra light porous metal material is a class novel multifunction material that occurs along with material preparation and developing rapidly of Machining Technology in the last few years.Its core body has high porosity, its micro-structural can be divided into disorder and order two large classes by regular degree, the former comprises closed-cell aluminum foam, and the latter comprises two-dimensional lattice material (such as ripple struction) and three-dimensional truss structure (such as pyramid structure, tetrahedral structure).
At present, dot matrix sandwich is as the metal species composite, because himself damping is less, do not have the approach of loss of energy, so it has born defective aspect vibration damping.
Summary of the invention
The object of the present invention is to provide a kind of in conjunction with pyramid dot matrix metal sandwich plate and epoxy resin base damping material advantage separately, realize that by compound mode functionality advantage separately is integrated, realize that several functions is blended in the pyramid dot matrix metal of filling epoxy resin base damping material all over the body-epoxy resin base damping composite construction and preparation method thereof.
For achieving the above object, preparation method of the present invention is as follows:
1) at first, adopt mold pressing or roll extrusion technology to form the pyramid core body stretching nets of punching rhombus net or smooth mistake, the pyramid structure core body is connected with panel makes pyramid structure dot matrix metal sandwich plate, wherein the relative density of pyramid dot matrix core body is 1～10%;
2) next adopts adhesive tape to encapsulate three limits of pyramid sandwich, will not encapsulate the limit and places vertically placement of maintenance under the clamp up;
3) then, under room temperature environment, epoxy resin base damping material and curing agent amine terminated polyether are mixed to get mixed slurry by the mass ratio of 1～3:1;
4) last, in the core body hole, room temperature left standstill 2～3 days or in 40～60 ℃ of curing ovens, obtained the pyramid structure dot matrix metal sandwich plate of filling epoxy resin base damping material with slurry perfusion.
The material of described rhombus net is carbon steel, stainless steel, fine aluminium or aluminium alloy.
Described stretching nets is expanded metal lath or aluminium expanded sheets.
Before described step 1) connects pyramid core body and panel are cleaned wipe oil and rusty stain.
Soldering, Laser Welding or performance of epoxy bonded are adopted in described connection.
The pyramid dot matrix metal of making by preparation method of the present invention-epoxy resin base damping composite construction is: the epoxy resin base damping material in the pyramid dot matrix metallic sandwich sheet that this composite construction is made of pyramid structure core body and panel and the pyramid structure core body mesopore that all is poured into this sandwich plate consists of.
Because viscoelastic material has high damping characteristic, can in quite wide frequency band, play the effect that suppresses vibration and noise, be widely used in damping vibration attenuation structure, be the effective means of control structure and instrument and equipment vibration, impact and noise.But viscoelastic material generally can not become the structural material in the engineering because modulus is excessively low, and the present invention combines the mutual supplement with each other's advantages that reaches the two with the two, becomes a kind of light-high-strength engineering damping material.The present invention uses the mechanical property of pyramid dot matrix metal sandwich structure excellence and the separately advantage of epoxy resin base damping material vibration damping and energy-absorbing, with the advantage of two kinds of structure composites in conjunction with both, realize multi-functional coupling, obtain the more excellent structure function material of combination property.Compare with the legacy cellular structure, the present invention uses the pyramid dot matrix through-hole structure, and compound with the epoxy resin base damping material of being more convenient for has lower manufacturing cost.
