Embodiment 1

[0027] like figure 1 As shown, Example 1 is a five-layer continuous carbon fiber reinforced polyether ether ketone fiber metal laminate, which consists of three layers of 0.3mm thick TA2 titanium plate 3, two layers of continuous carbon fiber reinforced polyether ether ketone prepreg 4 composition.

[0028] The specific preparation method is as follows:

[0029] In the first step, the continuous carbon fiber is impregnated through the modified polyether ether ketone chloroform solution at a speed of 15m / min at room temperature, and then evenly arranged on the roller to form a unidirectional prepreg with a carbon fiber volume content of 50%.

[0030] The second step is to rinse the surface of the TA2 titanium plate 3 with distilled water to remove surface pollutants; then wipe the surface of the TA2 thin plate 3 with acetone to remove surface grease; then put the TA2 titanium plate 3 into nitric acid and 60g / L of 350g / L In a mixed acid solution composed of hydrofluoric acid,...

Embodiment 2

[0034] This embodiment is a three-layer continuous carbon fiber reinforced PEEK fiber metal laminate, which is composed of two layers of 0.1 mm thick TA1 titanium plate 3 and one layer of continuous carbon fiber reinforced PEEK prepreg 4 .

[0035] The specific preparation method is as follows:

[0036] In the first step, the continuous carbon fiber is impregnated through the modified polyether ether ketone powder chloroform solution at a speed of 18m / min at room temperature, and then evenly arranged on the roller to form a unidirectional prepreg with a carbon fiber volume content of 60%.

[0037] In the second step, rinse the surface of the TA1 titanium plate 3 with distilled water to remove surface pollutants; then wipe the surface of the TA1 titanium plate 3 with isopropanol to remove surface grease; then put the TA1 titanium plate 3 into nitric acid and In a mixed acid solution composed of 60g / L hydrofluoric acid, at 40 o Pickling under C for 40s to remove the surface ox...

Embodiment 3

[0041]This embodiment is a five-layer continuous carbon fiber reinforced polyetheretherketone fiber metal laminate, which is composed of three layers of 0.5mm thick TC4 titanium plate 3 and two layers of continuous carbon fiber reinforced polyetheretherketone prepreg.

[0042] The first step, the preparation of prepreg: at room temperature, the continuous carbon fiber is impregnated through the modified polyether ether ketone chloroform solution at a speed of 20m / min, and then evenly arranged on the roller to make a single carbon fiber with a volume content of 60%. to prepreg.

[0043] The second step, metal sheet pretreatment: rinse the surface of TC4 titanium plate 3 with distilled water to remove surface pollutants; then wipe the surface of titanium plate with acetone to remove surface grease; then put TC4 titanium plate 3 into nitric acid of 350g / L and 60g / L hydrofluoric acid mixed acid solution, at 40 o Pickling under C for 40s to remove the surface oxide layer; finally ...

Abstract

The invention discloses a method for preparing continuous carbon fiber enhanced polyether-ether-ketone matrix fiber metal laminates and belongs to the field of preparation of composite materials. The method comprises the following steps: by utilizing continuous carbon fibers and a modified polyether-ether-ketone resin solution, preparing a continuous carbon fiber enhanced polyether-ether-ketone prepreg; sequentially performing degreasing treatment, acid pickling and anodic oxidation treatment on metal plates; alternatively laying the treated metal plates and the continuous carbon fiber enhanced polyether-ether-ketone prepreg, performing hot-press curing and forming on the metal plates and the prepreg in a mold, and naturally cooling, thereby obtaining the carbon fiber enhanced polyether-ether-ketone matrix fiber metal laminates. The fiber metal laminates prepared by the invention have the advantages of high toughness, high strength, difficulty in processing, environmental friendliness and no pollution.

Description

technical field [0001] The invention relates to a method for preparing a fiber metal laminate, specifically a method for preparing a continuous carbon fiber reinforced polyether ether ketone matrix fiber metal laminate, and belongs to the field of composite material preparation. Background technique [0002] Fiber Metal Laminates (FMLs), which were developed for the high fatigue crack area of ​​civil aircraft in the early stage, are laminated alternately by fiber composite materials and metal sheets, and cured for a period of time under a certain temperature and pressure A kind of interlayer hybrid composite material is formed later, so it is also called super hybrid laminates (Super Hybrid Laminates). [0003] At present, the FMLs used in aerospace are generally thermosetting composite laminates, which have many defects such as poor toughness and difficult forming, which hinder the application of such materials in the manufacturing process of mass products. Studies by fore...
