Process Autoclave moulding
The process takes place in an autoclave, where it is possible to create pressure and heat at the same time.
Layers of pre-impregnated fibres (prepreg) are piled with varying fibre orientation, to form the desired thickness above the forming tool.

The prepreg is pressed down to the forming tool by pressure. Following heating hardens the matrix and the laminate gets the desired shape.

The process is very versatile and gives a very uniform quality, as pressure and heat can be regulated very precisely. Any geometry can be produced. On the other hand, it is very costly and time requiring.
