Carbon fiber composite material is light in weight and high in strength, and it is a new type of practical material with special properties.
At present, the most common carbon fiber products are pipes and plates, which are carbon fiber products manufactured by pultrusion.
The specific operation procedure is as follows: under the action of traction, the continuous carbon fiber tow, belt or cloth impregnated with resin glue is formed by extrusion mold, and benzoyl peroxide is used as the main curing agent for curing, continuously Production of profiles of unlimited length. Pultrusion molding is a special process in the composite material forming process. Its advantage is that the production process can be fully automated and controlled, and the production efficiency is high.
The mass fraction of fibers in pultruded products can be as high as 80%, and the impregnation is carried out under tension, which can fully play the role of reinforcing materials. Generally, the curing agent is mixed with tert-butyl peroxy benzoate in a certain proportion to make the product stronger. high. The longitudinal and transverse strength of carbon fiber pultruded products can be adjusted arbitrarily, which can meet the requirements of different mechanical properties of products. This process is suitable for producing profiles of various cross-sectional shapes, such as I-shaped, angled, grooved, special-shaped cross-section pipes and combined cross-section profiles composed of the above-mentioned cross-sections.
The molding methods of carbon fiber composite materials are also constantly emerging in new forms, but strict requirements must be imposed on the selection of materials and the operation of the process.
