preparation example Construction

[0039] The present invention also provides a method for preparing the above-mentioned metal composite plate, wherein the method includes the following steps:

[0040] 1) making the fiber penetrate the two end faces of the metal foam;

[0041] 2) filling the filler in at least part of the pores of the metal foam;

[0042] 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.

[0043] The method of the present invention is used to prepare the above-mentioned metal composite plate, and the metal plate, fiber, filler and metal foam are the same as above. In addition, the insertion direction of the said fiber etc. are the same as above.

[0044] 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 of the metal foam are filled with the filler.

[0045] In a preferred embodiment ...

Embodiment 1

[0051] 1) The glass fiber bundle (diameter 0.05-0.1mm) runs through the aluminum foam (length 200mm, width 100mm, thickness 2mm) longitudinally (that is, in the length direction), with a through-hole structure and a pore diameter of 0.5mm-5.0 mm, with a porosity of 95%), wherein the longitudinally penetrating fiber bundles are located parallel to each other on the middle plane in the thickness direction of the foamed aluminum, in addition, the longitudinally penetrating fiber bundles are evenly distributed in the width direction of the foamed aluminum, and The distance between adjacent fiber bundles is 1 mm.

[0052] 2) Place the foamed aluminum that runs through the fibers in a container, and then put liquid epoxy resin (purchased from Buehler, USA, brand 20) mixed with glass fibers (3-80 μm in diameter and 100-300 μm in length) -8136-128) into foamed aluminum, place the vessel in a vacuum drying oven, vacuumize, and then cure at 25°C for 4 hours after the bubbles dissipate t...

Embodiment 2

[0055] Carry out according to the method of embodiment 1, the difference is that the distance between adjacent fiber bundles on the same plane is 2.5mm. 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 production method thereof. The metal composite plate is produced through clamping and binding a foam metal fiber layer by two metal plates, wherein the foam metal layer is formed by using foam metal, fibers and a filler, the fibers are interwoven in two end surfaces of the foam metal, and at least parts of apertures of the foam metal are filled with the filler. The interlayer bonding force between each of the upper and lower metal plates and the middle layer of the metal composite plate is high.

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 panel, wherein the metal composite panel is formed by clamping two metal plates and combining a foamed metal fiber layer, wherein the foamed metal fiber layer is composed ...
