preparation example Construction

[0042] The present invention also provides a method for preparing the above-mentioned metal composite plate, wherein the method includes the following steps:

[0043] 1) making the first fiber and the second fiber respectively penetrate the two end faces of the metal foam;

[0044]2) filling the filler in at least part of the pores of the metal foam;

[0045] 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.

[0046] The method of the present invention is used to prepare the above-mentioned metal composite plate, and the metal plate, first fiber, second fiber, foam metal and filler are the same as above. In addition, the insertion direction etc. of the said 1st fiber and the 2nd fiber are the same as above.

[0047] According to the present invention, preferably, in step 2), more than 90% of the pores of the metal foam are filled with the filler, more preferably, the pores o...

Embodiment 1

[0055] 1) The glass fiber bundle (0.05-0.1mm in diameter) runs through the aluminum foam (200mm in length, 100mm in width and 2mm in thickness) transversely (width direction) and longitudinally (lengthwise direction), with a through-hole structure and a pore diameter of 0.5mm-5.0mm, porosity 95%), in which, the fiber bundles running through the transverse direction are parallel to each other and evenly distributed in the length direction of the aluminum foam, and the fiber bundles running through the longitudinal direction are parallel to each other and evenly distributed on the aluminum foam In the width direction, the transversely penetrating fiber bundles and the longitudinally penetrating fibers are located on the same plane and are perpendicular to each other to form a plane grid structure. The plane grid structure is located on the middle plane in the thickness direction of the aluminum foam. The distance between adjacent fiber bundles is 1 mm.

[0056] 2) Place the foam...

Embodiment 2

[0059] Carry out according to the method of embodiment 1, the difference is that the distance between adjacent fiber bundles on the same plane is 2.5 mm. 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 and a filler; the first fibers and the second fibers respectively penetrate through two end faces of the foam metal; 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...
