preparation example Construction

[0035] The present invention also provides a method for preparing the above-mentioned metal composite plate, wherein the method includes the following steps:

[0036] 1) Make the first fiber penetrate the two end faces in the length direction of the metal foam, make the second fiber penetrate the two end faces in the width direction of the metal foam, and make the third fiber penetrate the The two end surfaces in the thickness direction of the metal foam, and making the first fiber, the second fiber and the third fiber intersect to form a three-dimensional network structure;

[0037] 2) filling at least part of the pores of the metal foam with the filler to obtain a metal foam fiber layer;

[0038] 3) The upper and lower metal plates and the foamed metal fiber layer are fastened together through vibration friction welding to form an integral body.

[0039] The method of the present invention is used to prepare the above-mentioned metal composite plate, and the metal plate, fi...

Embodiment 1

[0048] 1) The glass fiber bundles (0.05-0.1mm in diameter) run through the aluminum foam (200mm in length, 100mm in width and 20mm in thickness) along the length direction, width direction and thickness direction respectively, with a through-hole structure and a hole diameter of 0.5mm -5.0mm, porosity 95%), the glass fiber bundles are evenly distributed in the length direction, width direction and thickness direction of the metal foam, and the distance between adjacent fiber bundles on the same plane is 1mm. Cloth (that is, the glass fiber bundles penetrating in the length direction are evenly distributed on the planes in the width direction and thickness direction, and the distance between two adjacent fiber bundles on the planes in the width direction and thickness direction is 1 mm, ; The glass fiber bundles running through in the width direction are evenly distributed on the planes of the length direction and the thickness direction, and the distance between two adjacent fi...

Embodiment 2

[0052] According to the method of Example 1, the difference is that the glass fiber bundles are evenly distributed in the length direction, width direction and thickness direction of the metal foam, and the distance between adjacent fiber bundles on the same plane is 2.5mm. arranged. A metal composite sheet A2 was obtained in the same manner.

Abstract

The invention relates to the field of metal composite materials and discloses a metal composite plate and a preparation method thereof. The metal composite plate is formed by clamping and combining two metal plates and a foam metal fiber layer, wherein the foam metal fiber layer is formed from a foam metal, first fibers, second fibers, third fibers and a filler; the first fibers penetrate through two end faces of the foam metal in a length direction; the second fibers penetrate through two end faces of the foam metal in a width direction; the third fibers penetrate through two end faces of the foam metal in a thickness direction; the first fibers, the second fibers and the third fibers intersect to form a three-dimensional network structure; and at least partial ports of the foam metal are filled by the filler. According to the metal composite plate provided by the invention, the interlayer binding force between the upper and lower metal plates and the intermediate layer is higher.

Description

technical field [0001] The invention relates to a metal composite plate and a preparation method thereof. Background technique [0002] At present, the metal composite sheet is usually formed by laminating a metal sheet, a prepreg fiber cloth and a metal sheet, and then performing hot pressing. However, in the metal composite plate obtained by the above method, the interlayer bonding force between the upper and lower metal plates and the middle layer needs to be further improved. Contents of the invention [0003] The object of the present invention is to provide a metal composite plate with high interlayer bonding force between the upper and lower metal plates and the middle layer and its preparation method. [0004] In order to achieve the above object, the present invention provides a metal composite board, wherein the metal composite board is formed by sandwiching two metal plates and combining a foamed metal fiber layer, wherein the foamed metal fiber layer is made o...
