preparation example Construction

[0028] Simultaneously, the present invention also provides a kind of preparation method of above-mentioned fiber metal laminated board, comprises the following steps:

[0029] S1, distributing chopped fibers on the surface of the fiber cloth;

[0030] S2. Acupuncture the chopped fibers on the surface of the fiber cloth with a needling machine, so that the chopped fibers are partially inserted into the fiber cloth;

[0031] S3, pre-impregnating the fiber cloth with chopped fibers inserted on the surface in the bonding resin;

[0032] S4. Laminate the pre-impregnated fiber cloth with the metal layer so that the surface of the fiber cloth with chopped fibers faces the metal layer; then hot press to cure the bonding resin and combine the fiber cloth and the metal layer into one, The fiber metal laminate was obtained.

[0033] The fiber cloth used in the present invention is a conventional fiber cloth in the field. As mentioned above, for example, it can be one or more of glass f...

Embodiment 1

[0058] This example is used to illustrate the fiber metal laminate and its preparation method disclosed in the present invention.

[0059] The fiber cloth is made of glass fiber cloth (200mm×200mm) with a thickness of 0.4mm. The material of the metal layer is aluminum alloy 6061, and the thickness of the metal layer is 0.4 mm.

[0060] Chopped fibers are glass fibers with a cross-sectional diameter of 14 μm and a length of 15 mm.

[0061] Spread the fiber cloth in a solution filled with ethanol, add 100g of chopped fibers uniformly under the action of 25KHz ultrasound, and take out the chopped fibers to dry after they are deposited on the surface of the fiber cloth.

[0062] The fiber cloth with chopped fibers distributed on the surface is needle-punched on the needle-looming machine, and the needle-punching density is 200 needles / cm 2 , The acupuncture depth is 0.3mm.

[0063] The excess chopped fibers were then removed with 0.2 MPa compressed air.

[0064] Immerse the fi...

Embodiment 2

[0069] This example is used to illustrate the fiber metal laminate and its preparation method disclosed in the present invention.

[0070] The method of Example 1 was used to prepare fiber metal laminates. the difference is:

[0071] The thickness of the metal layer is 0.2mm.

[0072] The metal layer, the fiber cloth, the metal layer, the fiber cloth, and the metal layer are stacked in sequence, and the anodized film on the surface of the metal layer is bonded to the resin layer on the surface of the fiber cloth.

[0073] A fiber metal laminate S2 was obtained.

Abstract

The invention provides a fiber-metal laminated plate. The fiber-metal laminated plate solves the problem of a weak binding force between a metal layer and a fiber cloth in the existing fiber-metal laminated plate. The fiber-metal laminated plate comprises a metal layer, a resin binder layer and a fiber cloth and the metal layer, the resin binder layer and the fiber cloth are orderly stacked, chopped fibers are arranged between the resin binder layer and the fiber cloth and each one of the chopped fibers has a first part inserted in the fiber cloth and a second part fixed in the resin binder layer. The invention also discloses a preparation method of the fiber-metal laminated plate. The fiber-metal laminated plate has a strong binding force between the metal layer and the fiber cloth.

Description

technical field [0001] The invention belongs to the technical field of manufacturing fiber-metal laminated structural composite materials, and in particular relates to a fiber-metal laminate and a preparation method thereof. Background technique [0002] Aluminum alloy materials have lower density and higher strength and impact resistance, and have good machinability and low cost. Therefore, it has been widely used in the aerospace field since the early 1930s. However, aluminum alloy materials have some limitations such as low fatigue life and corrosion resistance, which limit their further application value. The glass fiber and carbon fiber composite materials invented in the 1940s and 1950s have high specific strength and specific stiffness, and have good fatigue properties and corrosion resistance. However, the out-of-plane transverse strength and impact resistance of this laminated composite material The performance is poor, and the interface between the layers is pron...
