Abstract

The invention relates to a manufacturing method of a high-performance composite carbon fiber guide tube. After mixing carbon fibers composed of chopped carbon fibers and ground carbon fibers, organic binders and solvents, the solvent is removed, and the surface is coated with organic binders. The composite carbon fiber of the agent is mixed with water and dispersant to form a carbon fiber mixed slurry, which is formed into a composite carbon fiber guide tube pre-product by vacuum suction molding; it is dehydrated by heating with hot steam or hot air, and the insolubilization and insolubilization treatment are completed. ; and then through carbonization or graphitization treatment, the finished product of the composite carbon fiber guide tube is obtained. The composite carbon fiber guide tube prepared by the invention has the characteristics of good heat insulation performance, good oxidation resistance, low heat capacity and high strength, and the production process is simple, the cost is low, the shape and size of the finished product are controllable, and the density is adjustable; It is not easy to crack, has good self-support and long service life; after surface treatment, it can also have excellent anti-oxidation performance and further improve the service life.
