Filament winding consists of winding resin impregnated fibers or rovings of glass, aramid, or carbon on a rotating mandrel inwards predetermined patterns. The method provides the greatest command over fiber placement as well as uniformity of structure. In the moisture method, the fiber picks upwards the depression viscosity resin either past times passing through a trough or from a metered application system. In the dry out method, the reinforcement is inwards the preimpregnated form. After the layers are wound, the element is cured as well as removed from the mandrel. Traditionally used to arrive at trace per unit of measurement area vessels, rocket motor cases, tanks, ducting, golf game monastic tell shafts as well as line-fishing rods, filament winding engineering has been expanded, as well as noncylindreical, nonspherical composite parts are straight off commonplace. Typical thermoset resins used inwards filament injure parts include polyesters, vinyl esters, epoxies, as well as phenolics.
