Abstract

The application provides a method for forming a fiber-aluminum alloy composite material part, which includes the following steps: 1. Cutting the aluminum alloy plate and fiber cloth according to the shape of the part; 2. Carrying out solid solution treatment to the aluminum alloy plate, and immediately The melted aluminum alloy plate is pre-pressed, so that the surface glued with the fiber cloth is evenly distributed with grid-shaped grooves, and then the pre-pressed aluminum alloy plate is quenched; 3. The quenched aluminum alloy plate is Degreasing treatment, and prepreg the fiber cloth in epoxy resin glue; 4. Make sandwich panels in the order of aluminum alloy plate-fiber prepreg-aluminum alloy plate, and pre-preg the sandwich panel 5. Place the obtained sandwich panel in a stamping mold, close the mold, keep warm and solidify to obtain a fiber-aluminum alloy composite material part. This method overcomes the problem of low elongation in the forming process of fiber materials and improves the strength of composite parts.

Description

technical field [0001] The present application relates to the technical field of composite materials, in particular to a method for forming fiber-aluminum alloy composite parts. Background technique [0002] Due to the advantages of high specific strength, specific stiffness and good corrosion resistance, fiber-reinforced resin-based composite materials are widely used in aerospace and automobile and other transportation fields. However, the inherent defects of the resin itself, such as: easy aging, easy creep, poor flame resistance and other shortcomings, these defects limit the further application of fiber-reinforced resin-based composite materials. In order to overcome these shortcomings of the resin matrix, aluminum alloys can be combined with fiber composite materials, so that while overcoming the weakness of poor heat and humidity resistance, the characteristics of good plasticity, impact resistance and ease of processing of aluminum alloys can be brought into play. I...
