Composite material

Abstract

The invention provides a composite material which is characterized by being prepared from macromolecular thermosetting high-strength resin, a fibrous reinforcing material and a curing crosslinking agent. According to specific weight proportions, the macromolecular thermosetting high-strength resin is 80% of epoxy resin, the fibrous reinforcing material is 20% of glass fiber, boron fiber and carbonfiber, and the curing crosslinking agent is any one or two of fatty polyamine, aromatic amine and polyamide. The composite material disclosed by the invention has the beneficial effects that the epoxy resin composite material is prepared into a fishing rod and has the advantages of light weight, good mechanical property and smooth and dense surface.

Description

technical field [0001] The invention belongs to the field of fishing gear, and in particular relates to a composite material. Background technique [0002] At present, in the production of fishing rods, the most used resin matrix is ​​high temperature curing phenolic resin and medium temperature curing epoxy resin. Phenolic resin has the advantages of low price, but due to the discharge of water and other low molecular products during the curing process, many micropores and bubbles are generated inside and on the surface of the blank, which affects the mechanical properties and appearance of the product, so it can only be used for Production of lower grade fishing rods. However, epoxy resin has no low-molecular products discharged during the curing process, and the surface of the product is smooth and dense, and has excellent mechanical properties. Therefore, in the production of higher-grade fishing rods such as carbon fiber fishing rods and mixed fiber fishing rods, rings...

Problems solved by technology

At present, most of the epoxy resin matrix used by various manufacturers is dicyandiamide-accelerator curing system. This system has the advantages of good latent property and fast curing at medium temperature. Fiber solvents, these solvents are not only expensive, but also difficult to volatilize during pre-preg drying, so it is necessary to increase the drying temperature and prolong the drying time, which not only reduces production efficiency, but also easily causes resin gel reaction
