Tanks, Pressure Vessels, Torque Tubes, and More ▪ High Volume Production ▪ Longer Length Tubes
What is the Filament Winding Process?
Continuous strands of dry fibers are:
- Impregnated with epoxy resin (in situ)
- Wound onto a mandrel via precise CNC control at various angles
- Externally pressurized for compaction and then
- Heat cured to solidify
After curing, the solid composite form is extracted from the mandrel as a tube. In the case of a tank or other closed end vessel, the mandrel could be left inside the composite form or dissolved out via various methods.Request A Custom Quote
When do we use this process for composites?
For larger, longer parts and for higher quantity production runs. . Filament winding is best suited for medium to large diameter parts of longer lengths, for example 1" through 24" diameter structures with lengths from 10' to 20'. It is also the most automated process for producing tubing and tanks and is therefore best suited for higher quantity production runs.
