Abstract

The invention discloses a ceramic mould for carbon fiber reinforcement resin matrix composite forming and a preparation method thereof. Compared with the prior art, the ceramic mould for carbon fiber reinforcement resin matrix composite forming and the preparation method thereof have the advantages that the ceramic mould can be used in all carbon fiber composite forming technology except mould pressing, the mould preparation technology is simple, direct forming can be achieved, many times of mould turning is avoided, and the size is more accurate; ceramic materials of a special structure are adopted, reinforcing fiber materials are added, and compared with common mould materials such as metal and glass fiber reinforcement plastic, the advantages of being good in flame retardant property, low in thermal expansion coefficient, resistant to high temperature, chemical corrosion and wear, high in strength and hardness, long in usage period, low in cost and the like are achieved; high-quality enamel layers are adopted so that the surface glossiness is high, the product aftertreatment process is reduced, and the production efficiency is improved.

Description

Technical field [0001] The invention relates to the field of mold manufacturing, in particular to a ceramic mold used for forming carbon fiber reinforced resin matrix composite materials and a preparation method thereof. Background technique [0002] Carbon fiber reinforced resin matrix composites have a series of advantages such as high specific strength, specific modulus, good fatigue resistance, corrosion resistance, and strong designability. They can be used as structural materials to carry heavy loads and function as functional materials. , Has been widely used in aerospace, wind power blade manufacturing, transportation, construction engineering and sports equipment and other fields. [0003] Mold is the main process equipment for the manufacture of carbon fiber composite components, which is used to determine the structure, shape and surface quality of the parts. The design and manufacture of composite molds play a vital role in the product quality of composite materials. [...
