Process Filament winding
Process suited for the production of strong and reatively thin (max. 2,5 o/oo of diameter) hollow composite parts with a rotational symmetry, such as tubes, containers, masts and wings.The inside surface is very smooth but outside surfaces are rougher.

The fibre material (a preformed tape or a hybrid thread) is wound from a reel on a mandrel, after having being wetted in the matrix bath. The mandrel is heated and exposed to pressure. After cooling the part can be removed.

It is a low cost process that gives a very uniform quality.
It has a medium cycle time per part, and produces small to medium series.
