Explanation

autoclave is a kind of vessel equipment that assimilates resin based composite materials components and can be heated and pressurized as required. It is usually cylindrical and belongs to high-pressure vessel. It mainly consists of tank system, heating system, cooling system, air storage and pressurization system, blowing system, vacuum system, control system, lifting platform and guide rail system, etc. The forming process of composite materials parts generally requires heating and pressurization system pressurization. Heating is realized by the heating system, and the pressure is realized by the gas storage pressurization system. The pressurized gas is mostly air, and inert gases such as nitrogen and carbon dioxide are only used at higher temperatures. The blowing system helps to improve the uniformity of the white temperature distribution of the tank body. The vacuum system provides a white vacuum environment for the system after packaging the workpiece blank. The autoclave can be used for forming a variety of composite materials structures, such as laminated structures, sandwich structures, adhesive structures and sewing structures. When the autoclave is used. First, the composite materials workpiece blank is sealed on the mold with a vacuum bag. Under the vacuum state, the workpiece preparation is completed through the process steps of temperature rise - pressure increase - heat preservation - temperature drop and pressure relief. The autoclave molding process has strong controllability of temperature and pressure. The prepared composite materials parts have small dimensional tolerance, low porosity, high quality and stable performance. It is widely used in the manufacturing of composite materials structural parts of aerospace vehicles. Especially in the manufacturing of the main load-bearing structure. Such as B787 composite materials central wing box, A350 composite materials fuselage, F18 composite materials vertical tail and large plastic stiffened cylindrical structure for aerospace, etc.
