Filament Winding

Filament winding, widely used in the manufacture of tanks, pipes, and other cylindrical parts, is a process where resin saturated continuous fibers are wrapped around a rotating mandrel to create an axially symmetric structure with a high degree of structural integrity.

PROCESS OVERVIEW

Filament Winding

The filament winding process can incorporate a variety of resin systems and fiber types depending on the end-use part application. In this process, continuous rovings, yarns or tow are first pulled through a catalyzed resin bath. Excess resin is removed from the fibers which are then guided onto a rotating mandrel or mold via a carriage arm that moves along the length of the mandrel ensuring the fibers are evenly applied. The movement of the carriage arm and the rotation speed of the mandrel are synchronized through automated controls to achieve precise fiber placement and structural integrity of the laminate. Once the desired laminate thickness is achieved, the part is allowed to cure either at room temperature or with the addition of heat and is then removed from the mandrel for additional processing.
