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 laminat...

Embodiment 1

[0038] A fiber metal laminate component, the manufacturing method of which comprises the following steps:

[0039] Pretreat the metal laminate, specifically: use No. 240 sandpaper to grind the metal laminate; use the existing technology to degrease the polished metal laminate, pickle and deoxidize, and alkali wash and neutralize; use ultrasonic After washing with water, dry in a drying oven at a temperature of 60°C for 30 minutes; use a phosphoric acid anode to oxidize the dried metal laminate (refer to the prior art for specific operations), the oxidation time is 20 minutes, and the oxidation temperature is 50°C. The oxidation voltage is 20V; the oxidized metal laminate is dried to obtain the pretreated metal laminate.

[0040] The first step is to make a prefabricated fiber metal laminate component, specifically: select at least two layers of metal laminates stacked in the upper and lower directions, and lay a carbon fiber composite material layer between two adjacent layers...

Embodiment 2

[0044] Embodiment 2 is different from Embodiment 1 in that: the direction of the carbon fiber composite single layer and the metal laminate are perpendicular to each other (that is, laying at 90°).

[0045] The fiber metal laminate member obtained in this example is denoted as S2.

Embodiment 3

[0047] The difference between embodiment 3 and embodiment 1 is: from bottom to top, the metal laminate includes the first layer, the second layer and the third layer; between the first layer of metal laminate and the second layer of metal laminate, the lower layer of carbon fiber composite material The direction of the single layer and the metal laminate is the same, and the direction of the upper carbon fiber composite single layer and the metal laminate are perpendicular to each other; between the second metal laminate and the third metal laminate, the lower carbon fiber composite single layer and the metal layer The plates are oriented perpendicular to each other, and the upper carbon fiber composite single layer is oriented in the same direction as the metal laminate.

[0048] The fiber metal laminate member obtained in this example is denoted as S3.

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...
