Abstract

The invention discloses a carbon fiber reinforced resin powder material. The material comprises main raw materials and auxiliary materials; the main raw materials comprise, by mass, 50-60 parts of polyacrylonitrile carbon fibers, 40-50 parts of asphalt-based carbon fibers, 30-40 parts of IM8 carbon fibers, 10-15 parts of phenolic resin, 12-15 of epoxy resin and 13-15 parts of thermoplastic resin;and the auxiliary materials comprise, by mass, 5-8 parts of an antioxidant and 3-5 parts of a catalyst. The epoxy resin has strong adhesion, normal temperature operability, simple constructability andother good workability, and the thermoplastic resin has heat softening and cold hardening performances, so the main raw materials can improve the high temperature resistance and the corrosion resistance, and make the powder material have excellent thermodynamic performances; and the raw materials have low prices, so the powder material can be massively produced, thereby the practicality of the carbon fiber reinforced resin powder material is improved.

Description

technical field [0001] The invention relates to the field of carbon fiber materials, in particular to a carbon fiber reinforced resin powder material. Background technique [0002] Carbon fiber reinforced composite material is a composite material formed by using carbon fiber or carbon fiber fabric as a reinforcement and resin, ceramics, metal, cement, carbon or rubber as a matrix. Among many lightweight materials, it has high specific strength and specific rigidity, and the lightweight effect is very obvious. It is widely used in aerospace and military products. Applied in body structural parts, the weight reduction effect is particularly obvious. It is 50% lighter than steel materials and 30% lighter than aluminum materials. Therefore, it has attracted extensive attention from major automobile companies at home and abroad. , high strength, high temperature resistance, corrosion resistance, and excellent thermodynamic properties have been widely used in many fields such as...
