specific Embodiment approach 1

[0008] Specific implementation mode one: combine Figure 1 to Figure 5 To illustrate this embodiment, the laminated plate of this embodiment is composed of at least two metal plates 1 and at least one layer of carbon fiber composite material 2; the at least two metal plates 1 are stacked together, A layer of carbon fiber composite material layer 2 glued to the two adjacent metal plates 1 is laid between them, the thickness of the metal plate 1 is 0.2 mm to 0.4 mm, and the thickness of the carbon fiber composite material layer 2 is 0.15 mm. The carbon fiber model in this embodiment is T300, T700, T800 or T1000.

specific Embodiment approach 2

[0009] Specific implementation mode two: combination figure 1 This embodiment will be described. In this embodiment, there are two metal plates 1 and one carbon fiber composite material layer 2 . Such arrangement has higher specific strength and higher specific rigidity, and at the same time has higher fracture toughness and workability. Others are the same as in the first embodiment.

specific Embodiment approach 3

Abstract

The invention relates to a carbon fiber metal laminate. The invention aims at the problem that, so far, flight vehicle structure materials, which not only has high specific strength and high specific stiffness, but also has high fracture toughness and processability, are non-existent. The inventive laminate is composed of at least two metal plates and at least one carbon fiber composite material layer; at least two metal plates are superposed together, a carbon fiber composite material layer which is adhesively bonded with the two adjacent metal plates are laid between the two adjacent metal plates; the thickness of the metal plate is 0.2m-0.4m and the thickness of the carbon fiber composite material layer is 0.15mm. The inventive laminate has high specific strength and specific stiffness, high fracture toughness and processability, and is also excellent in fatigue property and loss tolerance property. The invention can be used as a structure material for aerospace flights, such as a skin material of large civil planes, and can also be used as alternative material of metal auto panels, magnetically levitated train, light bulletproof armor and ship, etc.

Description

technical field [0001] The present invention relates to a fiber metal laminate. Background technique [0002] With the development of aerospace technology, there is an increasing demand for structural materials that can reduce maintenance costs and reduce aircraft structural weight, and have longer durability and better damage tolerance. [0003] The current structural materials of aircraft mainly include two types: one is metal materials, which have certain rigidity and strength, good toughness and machinability, and high reliability. Commonly used metal materials include: aluminum and its alloys are the most widely used metal materials in the aerospace industry, with high strength, high fracture toughness, strong ability to prevent crack growth at fiber fractures, and strong corrosion resistance sex, and low cost. Aluminum alloys are usually used to manufacture missile skins, wings and some stressed components, such as spars, stringers, ribs, etc. The 6.4m-long air-laun...
