Abstract

The invention relates to the technical field of carbon-fiber-reinforced resins, particularly a carbon-fiber-reinforced resin powder material which comprises the following components in parts by mass: 50-75 parts of xylenol-formaldehyde resin, 30-45 parts of chopped carbon fiber, 15-22 parts of hydroxymethyl cellulose, 8-15 parts of N-methyl-acetamide, 2.6-4.5 parts of sodium nitrate, 6.8-7.9 parts of polyformaldehyde resin, 1.8-3.2 parts of ferric chloride and 4-10 parts of silicon carbide powder. By adopting the formula, the carbon fibers are subjected to surface treatment, thereby greatly enhancing the compatibility between the carbon fibers and the thermosetting material, and improving the binding property between the carbon fibers and the matrix resin. Besides, the carbon-fiber-reinforced resin powder has the advantages of simple forming technique, short period, low production cost and no environment pollution.

Description

technical field [0001] The invention relates to the technical field of carbon fiber reinforced resin, in particular to a carbon fiber reinforced resin powder material. Background technique [0002] Carbon fiber reinforced phenolic resin-based composites have been widely used in many fields such as aviation, aerospace, automobiles, and ships because of their light weight, high strength, high temperature resistance, corrosion resistance, and excellent thermodynamic properties. Carbon fiber in carbon fiber reinforced phenolic resin matrix composites can be roughly divided into two types: continuous carbon fiber and short carbon fiber. Continuous carbon fiber reinforced phenolic resin-based composites generally have better mechanical properties, but are not suitable for large-scale production due to their high manufacturing costs. Short carbon fiber reinforced phenolic resin-based composites can use the same processing technology as the resin matrix, such as compression molding...
