Problems solved by technology

[0004] The purpose of the present invention is to provide a carbon fiber tube processing technology, which solves the problem that the existing technology proposed in the background technology cannot completely remove the solvent during the curing process, thereby affecting the strength of the formed pipe, and at the same time In the molding process, it is not possible to classify and wind pipes with different functions, so that carbon fiber raw materials cannot be saved, resulting in a certain cost waste

Abstract

The invention discloses a novel carbon fiber tube processing process. The novel carbon fiber tube processing process comprises a solution preparation procedure, a solution immersion procedure, a winding forming procedure and a curing procedure. The Novel carbon fiber tube processing process is characterized by specifically including the steps that S1, a solution is prepared and then put in a container; S2, a carbon fiber composite material is immersed into the prepared solution so that the surface of the material is completely dipped in the solution; S3, the carbon fiber composite material with the solution is winded onto a winding die core, and the carbon fiber composite material is shaped through rotation of the winding die core; and S4, the shaped carbon fiber composite material is cured in a curing furnace. Curing is performed in the curing furnace with the constant temperature being 150 DEG C for one hour in the curing process, then the temperature of the curing furnace is decreased to reach the room temperature, meanwhile the curing furnace is made to be in a vacuum state through a vacuum pump for performing curing again for one hour, thus solvent is completely removed, and the shaping strength is not affected.

Description

technical field [0001] The invention relates to the technical field of carbon fiber, in particular to a novel carbon fiber tube processing technology. Background technique [0002] Carbon fiber tube, also known as carbon fiber tube, also known as carbon tube, carbon fiber tube, is made of carbon fiber composite material pre-impregnated with styrene-based polyester resin and heated and cured by pultrusion (twisting). In the process of manufacturing, various profiles can be produced through different molds, such as: carbon fiber round tubes of different specifications, square tubes of different specifications, sheets of different specifications, and other profiles: 3K can also be packaged in the production process. Surface packaging beautification and so on. [0003] The existing carbon fiber processing technology is: mixing solution, immersing in solution, winding molding, curing process, and the existing process cannot completely remove the solvent during the curing process...
