Abstract

The invention provides a solidification / forming / heat treatment integrated preparation method of a carbon fiber metal laminate curved surface piece, and belongs to the technical field of multi-layer plate preparation and forming. According to the method, carbon fiber resin composite materials and solid solution-state aluminum alloy plates are alternately laminated to obtain a non-solidified fiber metal laminate; and the non-solidified fiber metal laminate undergoes heating, double-side pressing, heat preservation, solidification, forming and aging treatment to obtain the carbon fiber metal laminate. By adopting the process, the solidification / forming / heat treatment process of the fiber metal laminate can be integrated to significantly improve the processing efficiency; under the action of normal stress, the shear strength between the fiber layers and the aluminum alloy layers is higher and the plasticity of the aluminum alloy plates is better; and double-side gas pressure forming is adopted, so that the rigid contact of molds is avoided and the surface quality of components is better.

Description

Technical field

[0001] The invention relates to the technical field of multi-layer boards, in particular to a solidification / forming / heat treatment integrated preparation method of a carbon fiber metal laminate curved part. Background technique

[0002] Aluminum alloy materials have the advantages of low density, high strength, good impact resistance, good workability and low cost, which enable them to be widely used in automobiles, construction, aerospace and other industries. However, the low fatigue life and poor corrosion resistance of aluminum alloys limit its further application. Although carbon fiber has high specific strength, high specific modulus, low density, good fatigue resistance and corrosion resistance, the out-of-plane transverse strength and impact resistance of carbon fiber are poor, and it is easy to peel off between layers. In order to combine the advantages of aluminum alloy materials and carbon fiber composite materials, while overcoming their respective s...
