Filament winding is a fabrication technique mainly used for manufacturing open or closed end structures. This process involves winding filaments under tension over a rotating mandrel.
Filament winding allows placing and alignment of the filaments where they are needed to give the resulting structure the required strength. Because filaments are only put where they are needed, in the quantities needed, a component of minimum weight consistent with the strength requirements can be produced. In many cases it is also possible to produce a component of complex shape as a unitary structure, whereas the same component produced e.g. by metal stamping would require a number of component parts to be formed and then welded together.

Fiberglass Epoxy Tubing Specifications
Excellent Strength-to-weight Ratio
One-fourth the weight of steel and 25 percent lighter than aluminum, fibreglass epoxy tubing is easier to handle, shortens assembly times and reduces the stress loads on component parts.
Standard 6 Bar Pressure Rating
Test pressure of 9 Bar, higher pressure ratings can be ordered.
Superior Corrosion Resistance
Offers significant reduction in lifecycle costs due to its trouble-free performance in chemical, high-moisture, salt water and other adverse environments.
Prevents the flow of electric current.
Transparent to x-rays, radio and television transmission
Can be used as a radome because it is not affected by electromagnetic radiation.
Shape Stability and Impact Resistance
Does not suffer from catastrophic failure, pipe will weep before bursting.
Excellent Thermal Stability
With a very low coefficient of thermal expansion, fibreglass epoxy tubing operates efficiently from -40 °C to 110 °C.
Will not interfere with magnetic fields, making it ideal for Magnetic Resonance Imaging (MRI) applications.
