Filament Winding

The filament winding process was initiated after World War II. It was first developed for high strength products for government military applications. It was later used starting in the 1960's for industrial corrosion resistant applications such as storage tanks, pipes, natural gas tanks, and automotive parts. Filament winding equipment is commonly found in either mechanically operated designs or computer controlled designs. Most commonly used in industrial pipes are 2 axis winding equipment. More complicated parts require higher axis machines. There are also continuous winding processes available for mass production volume. The raw materials used in the filament winding process are resin (unsaturated resin or epoxy resin), continuous fibers (glass fibers, carbon fibers, Kevlar®, or ceramic), curing agent, and additives. Fiber content can reach as high as 70 percent of the product. Filament winding is a type of production process in the composites industry that will never be eliminated.
