Abstract

The invention provides a method and equipment for preparing a multi-layer composite material and a structural damping composite material prepared by adopting the method and the equipment. The preparation process comprises the following steps: 1. by taking a matrix layer as a cathode and taking a first electrode used as a source of a first structural layer as an anode, depositing the first electrode onto the surface of the matrix layer and forming a first structural layer by utilizing electrical discharge deposition; and 2. by taking a second electrode used as a source of a second structural layer as an anode, depositing the second electrode onto the surface of the first structural layer and forming a second structural layer by utilizing electric discharge deposition. When the first structural layer and the second structural layer are respectively a first damping layer and a second damping layer formed by damping materials, the obtained multi-layer composite material is a structural damping composite material. Control mechanisms of the equipment used by the method include a mechanism for controlling electrode feed movement and a mechanism for controlling an electrode clamping part to clamp or replace the electrode.

Description

technical field

[0001] The invention belongs to the field of materials, and in particular relates to a method for preparing a multilayer composite material and equipment used in the method, and also relates to a structural damping composite material obtained by using the method and equipment. Background technique

[0002] While the mechanical equipment is highly efficient, automated and widely used, the vibration generated by the mechanical equipment will seriously affect the accuracy and stability of the instrument and cause structural fatigue, and the noise generated will also endanger the health of the surrounding personnel. Therefore, the research and development of materials with excellent vibration and noise reduction and mechanical properties is of great significance to the civil, military and aerospace industries, and damping materials are thus produced.

[0003] Damping materials are divided into three categories according to their characteristics: 1) Rubber and pla...
