Composite material structure and production method thereof

Abstract

The invention discloses a composite material structure and a production method thereof. The composite material structure comprises a base body, wherein a carbon fiber material and a prereg material cover the surface of the base body; the prereg material is immersed into the carbon fiber material to form a composite layer. The production method comprises the following steps of 1, preparing the basebody, the carbon fiber material and the prereg material; 2, coating the base body with the carbon fiber material; 3, brushing the prereg material onto the base body coated with the carbon fiber material so that the prereg material is immersed into the carbon fiber material to form a composite layer; performing drying. The composite material structure has the advantages that the yield resistance is high; the intensity is high; the tensile intensity is enhanced; the weight becomes light; meanwhile, the anti-corrosion performance is realized; in the processing and manufacturing process, the steel materials can be greatly saved, so that the material can be widely applied to various fields.

Description

technical field [0001] The invention relates to a material and a production method thereof, in particular to a composite material structure and a production method thereof. Background technique [0002] In the prior art, steel is often used in the fields of aerospace, aviation, automobile, electronics, machinery, chemical industry, light textile and other civil industries, sports equipment and leisure products, but it is inconvenient to use steel to process curved surfaces. If there is a welding process, the intersecting lines of the surface welding nodes are complicated, which brings great inconvenience to the manufacturing process. Moreover, the steel will rust when in contact with the air, and it is very difficult to remove the rust, and the corrosion resistance is poor. In today's extreme pursuit of lightweight equipment, if lightweight steel is used and the tube wall is thinned by pumping tube technology, it will lead to a decrease in safety performance and limit the u...

[0002] In the prior art, steel is often used in the fields of aerospace, aviation, automobile, electronics, machinery, chemical industry, light textile and other civil industries, sports equipment and leisure products, but it is inconvenient to use steel to process curved surfaces

If there is a welding process, the intersecting lines of the surface welding nodes are complicated, which brings great inconvenience to the manufacturing process

Moreover, steel will rust when in contact with air, it is very difficult to remove rust, and the corrosion resistance is poor.

In today's extreme pursuit of lightweight equipment, if lightweight steel is used and the tube wall is thinned by pumping tube technology, it will lead to a decrease in safety performance and limit the use of steel, so it is rarely used in competition-level frames. see steel frame
