FILAMENT WINDING
Filament winding consists of winding resin impregnated
fibers or rovings of glass, aramid, or carbon on a
rotating mandrel in predetermined patterns. The method
provides the greatest control over fiber placement and
uniformity of structure. In the wet method, the fiber
picks up the low viscosity resin either by passing
through a trough or from a metered application system. In
the dry method, the reinforcement is in the
preimpregnated form. After the layers are wound, the
component is cured and removed from the mandrel.
Traditionally used to produce pressure vessels, rocket
motor cases, tanks, ducting, golf club shafts and fishing
rods, filament winding technology has been expanded, and
noncylindreical, nonspherical composite parts are now
commonplace. Typical thermoset resins used in filament
wound parts include polyesters, vinyl esters, epoxies,
and phenolics.
