Embodiment 1

[0043] A method for preparing a network structure toughened biomimetic composite material structure according to this embodiment is carried out according to the following steps:

[0044] 1. Surface treatment of the metal mesh structure: Cut the TA1 alloy mesh with a wire diameter of 0.11 mm and 80 mesh into a suitable size as required, polish the surface burrs of the Ti mesh with emery cloth, soak the cut Ti mesh in acetone solution, and use Ultrasonic cleaning for 2 minutes, after drying, soak in a mixed solution of HF:HNO3:H2O=1:1:20 for 1 minute, remove the oil and scale on the surface of the metal mesh structure, and clean it with clean water after taking it out;

[0045] 2. Surface cleaning of titanium foil and aluminum foil: TA1 alloy foil with a thickness of 100 μm and 6061 aluminum alloy foil with a thickness of 300 μm are cut to a suitable size, polished with sandpaper, and cleaned with acetone to remove oil on the surface of the foil , choose the mixed solution of HF...

Embodiment 2

[0050] The difference between this embodiment and Example 1 is that in step 1, a TA1 alloy mesh with a wire diameter of 0.1 mm and 100 meshes is used to prepare the composite material. Other steps and parameters are the same as in Example 1.

Embodiment 3

[0052] The difference between this embodiment and Example 1 is that in step 2, TC4 alloy foil with a thickness of 100 μm and pure aluminum alloy with a thickness of 300 μm are used to prepare composite materials. Other steps and parameters are the same as in Example 1.

Abstract

The invention relates to a mesh-structure toughened bionic composite material and a preparation method of the structural component of the mesh-structure toughened bionic composite material. The bioniccomposite material is of a laminated composite structure which comprises a plurality layers of lamination units, wherein each lamination unit is formed by sequentially stacking metal mesh cloth, aluminum foil, carbon fibers, aluminum foil, metal mesh cloth and titanium foil from top to bottom. The structural component is prepared by sequentially stacking the metal mesh cloth, the aluminum foil, the carbon fibers, the aluminum foil, the metal mesh cloth and the titanium foil from top to bottom and then performing vacuum sintering.

Description

technical field [0001] The invention relates to a method for preparing structural parts of a network-like toughened biomimetic composite material, belonging to the technical field of composite materials. Background technique [0002] As the performance of aviation and aerospace engines continues to improve, higher requirements are placed on the performance of high-temperature structural materials, and engine materials are developing in the direction of "stronger, more rigid, more heat-resistant and lighter". Due to the unique laminated structure and special failure mode of intermetallic compound-based matrix composites, it not only has excellent properties of high strength, high modulus, and low density, but also has a strong ability to absorb impact energy. Therefore, in addition to being used as high-temperature structural materials for intermetallic compound-based composite materials, foreign developed countries have considered using this new type of structural material i...
