Description

Technical Field

[0001] The utility model relates to the technical field of carbon fiber nets, in particular to a high-strength carbon fiber net that is easy to shape. Background Art

[0002] Traditional reinforcement materials are mainly reinforced concrete and metal materials. The reinforcement construction of reinforced concrete is complicated, occupies a large space, has a high reinforcement cost per unit area, and the steel bars are prone to corrosion. The reinforcement of metal materials is mainly based on bonded steel and outsourced steel reinforcement. The steel plate is pasted on the surface of the reinforcement by epoxy resin adhesive, so that it bears stress together with the reinforcement, but it will increase the self-weight of the reinforced structure. At the same time, steel is easy to rust, and its corrosion resistance and durability are poor, so its application is relatively limited. Carbon fiber composite materials are gradually used in reinforcement materials due to their light weight, high strength, excellent corrosion resistance and fire resistance. At present, carbon fiber reinforcement materials are mainly carbon fiber cloth and carbon fiber board. They are pasted on the surface of the reinforcement by matching epoxy resin adhesive. The construction is simple and the reinforcement effect is obvious. The existing carbon fiber mesh is made of strands of carbon fiber yarn woven into warp and weft, and the carbon fiber yarn is composed of carbon fiber filaments. The carbon fiber mesh has a small overall force and is only suitable for bending reinforcement and shear reinforcement. The application range is relatively narrow. At the same time, it is also easy for the reinforcement material and the substrate to be loosely bonded, and it is easy to peel off and fall off. For this reason, we propose a high-strength carbon fiber mesh that is easy to shape. Utility Model Content
