Problems solved by technology

However, the FRP mold is not suitable for the molding process due to its low strength, and the manufacturing process needs to be turned over many times. The process is cumbersome and complicated, and it has strict requirements on the manufacturing temperature and environment; Oxygen resin is used as the resin matrix, and the operating environment is unfavorable to the health of personnel; at the same time, FRP molds have poor flame retardancy and low heat resistance temperature, and are not suitable for bismaleimide and other resin-based composite materials that require higher curing temperatures

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.
