Filament Winding Process
Traditional Filament Winding
In the filament winding process , continuous strands of resin-impregnated glassfiber are wound under tension onto a mandrel in precise geometric patterns tobuild up the part which is then cured to form the finished parts.

Continuous Filament Winding
Multiple laminate layers , composed of resin , reinforcement glass and other materials are applied to a rotating mandrel , which is formed from a continuous steel band continuously traveling in a cork-screw motion . The composite part is heated and cured in place as the mandrel travels through the line and then cut into a specific length with a traveling cut-off saw .
