Method for manufacturing fiber metal laminate component and device adopted in method

Abstract

The invention provides a method for manufacturing a fiber metal laminate component. The method comprises the following steps: first, manufacturing a fiber metal laminate component prefabricated part; secondly, putting a mold laminated with the fiber metal laminate component prefabricated part in an autoclave for creeping-curing compound molding to obtain a component; and thirdly, cooling the component, removing the mold, and rebounding to obtain the fiber metal laminate component. According to the method, the process flow is simplified, the process parameters are reasonably selected, appearance and performance synergistic manufacture is realized in the autoclave by utilizing the creep aging characteristic of metal and the cure molding characteristic of the carbon fiber composite material, and the problem that metal and a fiber enhanced composite material are not matched in deformation due to different rigidities after resin is cured can be effectively avoided; the fiber metal laminate component has small residual stress, uniform distribution and small rebound deformation after molding; and the defects, such as cracking, layering and the like, cannot be easily generated inside the fiber metal laminate component. The invention further provides a device adopted in the method. The device is concise in structure and convenient to manufacture.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a method for manufacturing a fiber metal laminate component and a device used therefor. Background technique [0002] With the development of aerospace technology, the speed of aircraft is getting faster and the range is getting farther, and new requirements are constantly being put forward for the density, strength, modulus and comprehensive performance of structural materials. However, currently commonly used aerospace structural materials (single metal or fiber-reinforced resin-based composites) are difficult to meet these requirements. In order to solve this problem, fiber metal laminates came into being. Fiber metal laminates combine the characteristics of metal impact resistance, easy processing and high strength and low density of composite materials, and have been widely used in the fields of civil aviation and military equipment. Although fiber metal laminates have e...

Problems solved by technology

The main problems of the secondary forming are as follows: 1. The processing technology is complicated, and it generally requires repeated processing, which requires high requirements for the secondary forming equipment; 2. The initial state of the material is limited by the secondary forming. Some studies have shown that the fiber metal laminate members formed by roll bending have strict requirements on the thickness of the laminate; third, due to the different strains of metal, resin, and fiber in the fiber metal laminate, and the laminate has anisotropy, the secondary Processing and forming are easy to cause defects such as delamination and cracks inside the formed component, and at the same time, the residual stress of the formed part is large, and the forming accuracy is difficult to control

Based on the current forming methods, although some simple shapes can be processed and formed, the forming efficiency and forming quality are not satisfactory, especially for the forming of complex structures. There is no particularly ideal forming method.
