Filament winding is a manufacturing process used to create composite materials by winding continuous strands of fiber, such as carbon or glass, around a rotating mandrel. This technique allows for the precise placement of fibers, resulting in strong and lightweight structures. The fibers are often impregnated with a resin, which hardens to form a solid composite once cured. This method is commonly used in industries like aerospace, automotive, and marine, where high strength-to-weight ratios are essential. Filament winding can produce various shapes, including tubes and tanks, making it versatile for different applications.
