Product Description
Process description

Composite autoclave is the key equipment to shape and produce polymer matrix composite component products.


Autoclave forming process is to blank the composite material, honeycomb sandwich structure or adhesive structure with a vacuum bag sealed in the mold, placed in autoclave, in a vacuum (or non-vacuum) state, after heating, pressure, insulation (In the temperature or high temperature) holding pressure, cooling pressure relief process, making it the desired shape and quality state of the molding process. Autoclave molding process is widely used composite structure, honeycomb sandwich structure and metal or composite adhesive bonding structure of the main one of the methods. Material molding is the use of autoclave to provide a uniform temperature and pressure to achieve curing environment, so get the surface and interior of higher quality, complex structure, a huge area of composite parts.


In addition to the molecular structure of the resin, the curing of the matrix resin of the composite material is also related to the other components (curing agent, adhesion promoter, etc.), external conditions (temperature, pressure and time factors play an important role in curing)Usually these three factors are said to be the main process parameters. All autoclave molding process methods must determine the corresponding process parameters according to the molecular mechanism of the matrix resin. Autoclave must have the function of controlling these process parameters.

Composite autoclave introduction


The composite autoclave is a kind of process equipment for the forming process of polymer matrix composite. The method of using this kind of equipment for forming process is called composite autoclave. Autoclave molding is the main method of manufacturing continuous fiber reinforced thermosetting composites. It is widely used in advanced composite structure, honeycomb sandwich structure and metal or composite bonding structure. When the material is molded, it is solidified by the uniform temperature and uniform pressure provided in the tank. Therefore, the composite material with high surface and internal quality, complex shape and large area can be obtained.


autoclave moulding method introduction


Composite autoclave molding is widely used at home and abroad. It is mainly used for the manufacture of large and complex aerospace FRP components, such as leather parts, ribs, frames, all kinds of wall panels, flooring and fairing. The forming method of hot pressing can also has some limitations. It is difficult to form a complex structure with this method. At the same time, this method has high requirements for the design of die, and the mold must have good thermal conductivity. Thermal rigidity and air tightness.


Basic Principle


The prepreg layer according to the requirements laid in the mould, and sealed in the vacuum bag into the autoclave, autoclave after heating, pressure, material curing reaction, make the prepreg blank into a desired shape and meet the quality requirements of the component process. The hot pressing tank forming method is the most common forming method for FRP components, which can form sandwich structures and laminates, and can also form composite components and adhesive components.



At present, there are several kinds of moulds suitable for temperature forming composite material in hot pressing tank: aluminum die, steel mould, carbon fiber / epoxy resin composite mold. Generally speaking, composite material members with high dimensional accuracy and high yield and small yield can be made of carbon fiber / epoxy composite mold. The aluminum mold is most suitable for components or flat products whose size accuracy is not too high. When the product is large batch, It is the most economical and practical to choose the steel die with high precision. The curing of composite matrix is related to the molecular structure of resin, and other components, such as curing agent, crosslinking accelerator and so on. The external conditions (temperature, pressure and time) affect the curing process.

Vacuum system

system introduction

It is composed of vacuum pump, vacuum pipeline, vacuum pipeline, standby pipeline and vacuum buffer tank. The vacuum is composed of pressure sensors, pneumatic valves and manual valves. There is a pressure leak alarm in every vacuum. Vacuum pipeline: to measure the route of every vacuum tube and gas pipeline. It is located on one side of the hot pressing tank. The vacuum pumping pipeline, a relative independence in working alone, when any one vacuum line when a fault occurs, the vacuum line can be cut off to the road, reducing the influence for the vacuum system and other vacuum pipeline, in order to take corresponding measures according to the actual situation, to ensure the stability and safety of the vacuum system.

Vacuum 1-20 Road, vacuum 1-20 Road, extraction separation, through PLC control vacuum pump and vacuum valve group to achieve process requirements.
