Filament winding is a process for fabricating a composite structure in which continuous reinforcements, either previously impregnated with a matrix material or impregnated during winding, are placed over a rotating form or mandrel in a prescribed way to meet certain stress conditions. This article describes the advancements in filament-winding and lists the advantages and disadvantages of filament winding. The article discusses the effects of fiber tension in filament winding and the selection of fibers, resins, and materials for filament winding. It discusses the three basic filament-winding patterns, such as helical, polar, and hoop. The article presents information on the applications of filament winding, including rocket motors, natural gas vehicle (NGV) tanks, and sporting goods. It recommends basic design guidelines for filament-winding design/manufacturing process and concludes with a discussion on fabrication recommendations.
