specific Embodiment approach 1

[0009] Embodiment 1: This embodiment is described in conjunction with FIG. 1. The carbon fiber metal composite laminate of this embodiment is composed of three metal plates and a carbon fiber composite material layer 1; the three metal plates are all aluminum plates or aluminum alloy plates, so A carbon fiber composite material layer 1 is wound on one of the three metal plates 2-1, and the other two metal plates 2-2 of the three metal plates are respectively fixed on the upper surface of the carbon fiber composite material layer 1 and on the lower surface, the metal plate has a thickness of 0.2 mm to 0.4 mm.

[0010] In this embodiment, a carbon fiber metal composite laminate with excellent mechanical properties is produced by using a carbon fiber reinforced composite material with high specific strength, specific stiffness, and corrosion resistance, and aluminum or aluminum alloy with excellent comprehensive performance, fatigue resistance, and impact resistance.

specific Embodiment approach 2

[0011] Specific embodiment two: the manufacture method of the carbon fiber metal composite laminated board of the present embodiment is finished like this: one, surface treatment: get three size and the metal plate that material is all identical, and carry out degreasing treatment and treatment successively to each metal plate pickling treatment, and finally wash it to neutral, use cold water spray to clean the surface of the metal plate, and then put it in a drying box to dry for later use. The three metal plates are all aluminum plates or aluminum alloy plates, and the thickness of the metal plates is 0.2mm to 0.4mm; 2. Winding carbon fiber composite material layer 1: the carbon fiber composite material layer 1 is hoop-wound and dipped on one of the three metal plates 2-1 after step 1 treatment The glue is made of carbon fiber, and the glue is made by mixing epoxy resin, m-phenylenediamine curing agent and absolute ethanol solvent according to the mass ratio of 1:0.1~0.18:0.1...

specific Embodiment approach 3

[0018] Specific embodiment three: the degreasing treatment in the step one of the present embodiment is completed in this way: wipe the surface of each metal plate with absorbent cotton moistened with acetone, and then wipe clean with cotton cloth after removing oil. Other processing steps are the same as in the second embodiment.

Abstract

A manufacturing method of a carbon fiber metal composite laminated plate relates to a manufacturing method of a fiber metal composite laminated plate. The method aims at solving the problems that no manufacturing methods for manufacturing aircraft structural material with high specific stiffness, high specific strength, tenacity and workability exist in China. The method comprises the following steps of: carrying out surface treatment to three pieces of metal plates; winding a carbon fiber composite material layer which is soaked in liquid cement on one of the metal plates, wherein, the liquid cement is prepared by epoxy resin, a metaphenylene diamine curing agent and an anhydrous alcohol solvent according to the mass ratio of 1:0.1 to 0.18:0.15 to 0.2; fixedly arranging another two metal plates on the upper surface and the lower surface of the carbon fiber composite material layer so as to be integrally put into a mould, and then treated with mould assembling, drying, solidification by adopting the method of gradient temperature increasing, and demoulding. The manufacturing method of the invention is simple and is easy for operation. The carbon fiber metal composite laminated plate manufactured by the method of the invention has the advantages of high specific stiffness, high specific strength, also high tenacity and workability of metal material, good fatigue property, and good damage tolerance capability.

Description

technical field [0001] The invention relates to a method for manufacturing a fiber metal composite laminated board. 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...
