Filament winding can be used to make structures which are highly engineered and meet strict tolerances. Products fabricated using the filament winding process are generally cylindrical products such as chemical and fuel storage tanks, poles, columns, pipes, stacks and pressure vessels.
Filament winding allows high fiber loading, giving high tensile strengths and resulting in high strength-to-weight ratio laminates. The process provides a high degree of control over part uniformity and fiber orientation. Continuous strand fiber reinforcement is fed through a resin binder bath and wound onto a rotating mandrel. The reinforcement feed runs on a trolley that traverses the length of the mandrel. The reinforcement is laid down in a predetermined geometric pattern to provide maximum strength in the directions required. When sufficient layers have been applied, the laminate is cured on the mandrel. The molded part is then removed from the mandrel. Some mandrels are collapsible to facilitate part removal.
