Filament Wound Tubes

Filament Winding is one of the oldest composite manufacturing processes yet is still widely used to create complex, lightweight structures designed to provide strong mechanical properties in specific applications.

Filament winding creates cylindrical shapes with very specific mechanical and thermal properties that are custom designed for the application. A CNC machine dips glass fiber into a custom-developed resin system. This impregnated glass fiber is then wrapped around a steel mandrel a specified number of times at engineered angles to create a tube. There are many critical variables to provide the desired outcome.

The resin system is specifically designed to provide mechanical and thermal properties. Some resins support the end product in operating in extreme temperatures. Others modify electrical conductivity or resistance. Resins can also be dyed to notate various characteristics or match a customer’s brand marketing scheme. The resin/glass combination also lends itself well to painting for similar outcomes.

The type and angle of the glass fiber provide mechanical properties. When fiber is laid down at up to an 85 degree angle relative to the mandrel, the resulting structure provides very high burst strength. These characteristics are needed in various pressure applications. When the fibers are wound closer to 30 degrees to the mandrel, the tube provides high mechanical performance axially (compressive and tensile strengths). Our machines can produce tubes up to 84” in length and wall thicknesses up to 1.5 inches.
