What is Filament Winding?

Filament winding is an automated open molding process that uses a rotating mandrel as the mold. Filament winding creates hollow structures of incredible strength. By cross-weaving in a variety of orientation, continuous rovings of carbon fiber, or fiberglass, are embedded in a resin matrix, the filament winding process results in an optimized product that is perfect for pressure vessels, aerospace components, golf clubs, military armaments, pipelines, tanks, gas cylinders, and hundreds of other uses. Wherever high strength is needed with lightweight, wherever durability and targeted performance characteristics are imperative, this manufacturing process is used.

Main Advantages

  • This can be a very fast and therefore economic method of laying material down.
  • Resin content can be controlled by metering the resin onto each fibre tow through nips
  • Fibre cost is minimised since there is no secondary process to convert fibre into the fabric prior to use.
  • Structural properties of laminates can be very good since straight fibres can be laid in a complex pattern to match the applied loads.
