Composite products produced by autoclave process account for quite 50% of the entire output of composite products, and its proportion in special fields is up to quite 80%. at the present , autoclave process, together of the forming methods of carbon fiber composite components, is additionally widely employed by many carbon fiber composite components manufacturers.

Prepreg autoclave technology is especially applied to the aerospace field: skin parts, ribs, frames, fairing, etc.; automotive field: body cover panel and structure parts, like inner and outer panel of the over, inner and outer panel of the door, top cover, wing plate, threshold beam, B-pillar, etc.; rail transportation: sleeper beam, side beam, etc.; boat industry, high-end commodity , etc.

According to the principle of autoclave process, the carbon fiber prepreg is laid on the mold consistent with the laying requirements, and therefore the blank is sealed within the dust bag and placed within the carbon fiber autoclave. within the vacuum state, after the heating, pressure, heat preservation, cooling and pressure relief procedures on the autoclave equipment, curing is achieved by using the uniform temperature and uniform distribution pressure provided within the autoclave. Thus, carbon fiber composite parts with top quality , complex shape and large area are formed.

The autoclave process may be a process developed for the assembly of the second generation of composite materials, which was formed within the 1940s, but it had been not until the 1960s that it had been gradually promoted and used. Especially within the production of all types of skin parts, it's played an enormous role and has been developed into a mature technology.

The prepreg autoclave may be a quite process equipment for the forming process of polymer matrix composites. Prepreg may be a composite made from resin matrix and reinforcement, and is an intermediate material within the manufacture of composite materials, which is formed of continuous fiber or fabric impregnated with resin matrix under strictly controlled conditions.

Technological Advantages

• Pressure uniformity: After the utilization of pressure , the pressure acts on the surface of the products through the dust bag , and therefore the normal pressure at each point is equal, in order that the parts are cured and formed under an equivalent pressure.

• Uniform temperature, adjustable: The massive vacuum autoclave heats the workpiece through circulating hot air flow within the equipment tank, and therefore the temperature difference between different places is little . The cooling system is provided at an equivalent time, in order that the temperature is strictly controlled within the range of the method setting.

• Wide application range: The mold is straightforward with high efficiency, not only suitable for giant complex surface plate, shell, but also suitable for easy shape plate, rod, tube, block. Besides, it also can be used for adhesive assembly, and little parts are often cured at a time quite one piece. The temperature and pressure conditions of autoclave can almost meet the forming process requirements of all polymer matrix composites;

• Stable and reliable molding process: The pressure and temperature uniformity within the autoclave can make sure the quality stability of the molded parts. The components made by carbon fiber autoclave forming process have lower porosity and even resin content, and therefore the mechanical properties of the parts made by autoclave forming process are more stable and reliable than those made by other autoclave forming processes. So far, the autoclave process has been utilized in the bulk of composite parts with high load bearing requirements within the aerospace field. Visit here: https://www.siniccn.com/
