This chapter examines the following concepts: process overview, filament winding, variations in filament winding, and fiber placement. Filament winding is the most important of the composites processes in terms of the number of users and the total number of parts made. Fiber placement is a more recent development and is a method that can be used to make highly complex parts, even some that could not reasonably be made with filament winding. The two filament winding methods that are the focus of this chapter wrap fibers (with resin) around a mandrel (a core) as the method of shaping the fibers and resins prior to curing. This chapter examines filament winding in detail, including some related processes that expand on its original capabilities. One of the major limitations of filament winding is the shape of the part that can be wound. Making composite parts on a mandrel has proven to be successful. The major manufacturing methods utilizing this concept are filament winding, fiber placement, and roll wrapping. Filament winding is, by far, the most prominent in terms of usage. However, fiber placement is becoming more important because of its ability to make parts of almost any shape. Filament winding is intended for making parts that have an axis of rotation and, in general, a convex cross-section.
