Abstract

The invention provides a forming process of a hollow carbon fiber product, and relates to the technical field of carbon fiber preparation. The process comprises the following steps that a polystyrenefoam raw material is poured into a core mold, and the mold is put in a vacuum hot pressing furnace to be formed; the core mold is put into an air bag; glass cloth and carbon cloth are wrapped around the core mold according to the shape of the core mold, so that a product prefabricated body is obtained; 3K carbon cloth is affixed to a cavity of a main body mold; the prefabricated body is put into the main body mold, an air inlet pipe is connected, and forming control is conducted; the main body mold is opened so as to obtain a product main body rough blank; a yarn-contained flash of the main body rough blank is removed; an accessory is prepared by using an accessory forming mold, and an accessory rough blank is obtained; the main body rough blank and the accessory rough blank are glued together; and the product rough blank is treated, so that a finished product is obtained. The process solves the problems of material missing or depression in a hollow carbon fiber formed product.

Description

technical field [0001] The invention relates to the technical field of carbon fiber preparation, in particular to a molding process for hollow carbon fiber products. Background technique [0002] Ordinary carbon fiber has been widely concerned due to its high specific surface area, good thermal stability, corrosion resistance, and excellent electrical and thermal conductivity. Compared with ordinary carbon fiber, hollow carbon fiber not only has the advantages of ordinary carbon fiber, but also has an additional inner surface due to the existence of hollow structure, which greatly improves its performance in adsorption, mass transfer, and catalysis. It has good application prospects in the fields of hydrogen storage industry, environmental protection and water purification. [0003] At present, air blow molding is widely used for hollow carbon fiber products in China, and the shape of the products is relatively smooth and round, which is suitable for products with simple mo...
