Abstract

The invention discloses a carbon fiber composite material autoclave forming method characterized by a mold with a heating system. A method of mold interior heating forming is adopted. The carbon fibercomposite material autoclave forming method characterized by the mold with the heating system comprises the following steps that the mold enters an autoclave; the mold is vacuumized; the autoclave ispressurized; the mold is heated; and mold release and forming are conducted. According to the carbon fiber composite material autoclave forming method characterized by the mold with the heating system, due to the design of the mold with the heating system and a pressurizing system, a carbon fiber composite material to be formed can be directly heated through the mold, the heating efficiency can be remarkably improved, the energy consumption is reduced, and the production efficiency of products is improved.

Description

technical field [0001] The invention relates to the technical field of carbon fiber composite material forming, in particular to a carbon fiber composite material autoclave forming method with a heating system in a mold. Background technique [0002] Carbon fiber has excellent properties such as high strength, high modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, electrical conductivity, heat transfer, low relative density and small thermal expansion coefficient, and is widely used in aerospace, cultural and sports equipment, and medical equipment. , new energy, civil construction, transportation, electronics, electrical and machinery and many other fields. However, in such a wide range of applications, carbon fiber is rarely used directly, and most of it is made into intermediate products or composite materials through deep processing. [0003] Composite autoclave molding process is the main method to produce high-quality ad...
