The flame-retardant high-toughness carbon fiber composite material for the overhead transmission conductor is prepared from the following components in parts by weight: 50 to 60 parts of polyacrylonitrile, 20 to 30 parts of single-layer graphene powder, 8 to 15 parts of bacterial cellulose, 5 to 10 parts of methyl methacrylate, 5 to 10 parts of 1,6-dibromohexane, 30 to 40 parts of thermosetting resin, 1 to 5 parts of nano magnesium hydroxide and 3 to 6 parts of nano-aerogel. The carbon fiber composite material disclosed by the invention has high toughness and good flame retardant property.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber composite materials, and in particular relates to a flame-retardant high-toughness carbon fiber composite material used for overhead power transmission wires. Background technique [0002] Carbon fiber is a special fiber with a carbon content greater than 90% made from polyacrylonitrile (PAN), pitch, viscose fiber, etc. through pre-oxidation, carbonization, and graphitization processes. It is an indispensable engineering material, and it is also widely used in civil fields such as sporting goods, transportation, medical equipment and civil engineering. The production process of PAN-based carbon fiber is simple and the comprehensive performance of the product is good, so it develops rapidly, and the output accounts for more than 90%, becoming the most important variety. [0003] Publication number CN102560746A discloses a method for preparing polyacrylonitrile / graphene composite-based carbon ...
