Problems solved by technology

[0002] Carbon fiber sporting goods at home and abroad (tennis rackets, badminton rackets, ski poles, golf clubs, boat paddles, bows and arrows, mountain sports cars), automobiles, aviation seats, special operations weapon manufacturing markets and other fields require molding (air pressure) forming operations, and In the molding process, nylon air ducts are traditionally used. Most of the nylon air ducts are straight lines, which cannot form special shapes such as bending, and complex operations such as sealing are required, which will affect the strength of the components.

Abstract

The invention discloses double-component air hose glue for a carbon fiber composite material compression molding forming process. The double-component air hose glue comprises the following components in parts by weight: a component A which consists of 30-50 parts of hydroxyl ended linear polybiorganic siloxane, 10-20 parts of padding, 5-15 parts of methyl silicon oil, 20-40 parts of solvent oil and 1-10 parts of additives, and a component B which consists of 20-40 parts of a cross-linking agent and 60-80 parts of solvent oil. The air hose glue disclosed by the invention is coated on expandable polystyrene foam; as the expandable polystyrene foam can be formed into various shapes, a carbon fiber material wrapped by the expandable polystyrene can be formed into various shapes directly when being baked at high temperature; as the air hose glue is good in release property and can be conveniently pulled out, a carbon fiber product of a certain shape can be formed, steps of adhesion and the like are saved when the glue is compared with the conventional glue, and the component strength is not affected. The invention further discloses a preparation method of the double-component air hose glue.
