What
is Filament Winding?
Filament
winding consists of winding continuous rovings of fiber onto
a rotating mandrel in predetermined patterns. This method
of manufacturing provides the greatest control over fiber placement
and uniformity of structure. In the wet winding method,
the fiber picks up resin either by passing through a resin bath
or from a metered application system. In the dry winding
method, the reinforcement is in the preimpregnated form termed
towpreg. After several layers are wound, the component
is cured
and removed from the mandrel (or in some cases the mandrel becomes
part of the component).
Filament
winding is traditionally used to produce pressure vessels,
pipe, rocket motor casings, tanks, ducting, golf club shafts
and other symmetric parts. |
