Problems solved by technology

When using physical vapor deposition or chemical vapor deposition, the coating layer usually produces a lot of thermal stress after it is combined with the substrate. In addition, both physical vapor deposition and chemical vapor deposition are limited to manufacturing coatings. Parts with layer thickness less than 0.1 mm, so this method is usually not suitable for parts with wear resistance requirements

Abstract

The invention discloses a preparation method of a fiber-reinforced metal composite material. The preparation method comprises the following steps: (1) preparing a metal layer; (2) preparing a fiber preformed body; (3) preparing a fiber-reinforced composite material; (4) performing die pressing, solidifying and forming; (5) performing after-treatment. The composite material successively comprises a metal surface layer, a metal boundary layer, a flexible transition layer and a fiber-reinforced composite material layer, wherein the flexible transition layer is a thermoplastic layer, and the stretching strength of the composite material in a circumferential direction is 550-650 MPa. According to the invention, a jointing process is not required to be determined according to material characteristics, the process is simple and controllable, requirements for equipment are low, the cost is low, the method can be suitable for fibers and metallic matrixes made of different materials, and the application range is wide. The fiber-reinforced metal composite material prepared by the preparation method disclosed by the invention has the advantages that a shape structure is flat, interlaminar internal stress is small, the weight is light, the strength is high, abrasion resistance and corrosion resistance are good, and the fiber-reinforced layer is durable, long in service life, good in practicality, and wide in market prospect.

Description

technical field [0001] The invention relates to the field of metal composite materials, in particular to a preparation method of fiber-reinforced metal composite materials. Background technique [0002] At present, with the requirement of energy saving and environmental protection, it is an inevitable direction for the development of the industry to continuously develop more energy-saving and environmentally friendly vehicles using lightweight structural materials, and fiber-reinforced and / or fabric-reinforced hybrid multi-layer composite materials are the key to manufacturing efficient lightweight structures. The main direction. [0003] But so far, the methods for manufacturing continuous fiber-reinforced metal matrix composites can be summarized into two categories: solid-phase method and liquid-phase method. However, the production cycle is long, and it is not suitable for the industrial mass production of thin plates and other profiles; although the solid-phase method ...
