Filament Winding

Filament winding is an ideal production method for producing cylindrical structures. Filament winding process has two different types. (A) Helical Filament Winding (B) Continuous Filament Winding. Fiberglass and catalyzed resin are wound over a rotating mandrel. Composite tanks, silos, ducts, water tanks, pipes and pressurized vessels are produced with this method. Polipol 3562 has high mechanical properties and good fiber wet-out. Polipol 3872-I is the preferred choice where high elongation at breaking point and chemical resistance is needed.

Filament winding is an ideal method for producing cylindrical structures.


Continuous Filament Winding Application
Glassfiber laminate is applied on to amoving mandrel with resin. Moving mandrel consists of a steel band which moves in the axial direction sliding over ball bearings. Pipes are produced on this steel band mandrel continuously. It is possible to produce pipes of various diameters with this technique. This production technique has 3 main zones. Raw material feeding zone, Curing zone and Cutting zone. First, a realese film (e.g. polyester film) is wound onto mandrel, followed by a surfacing veil. Glass roving and chopped glass, sand agregate and polyester resin are applied simultaneously on the rotating mandrel. After application of raw materials, pressure rolls help to release entrapped air inside the laminate. After curing, material is cut into the desired lengths.

Helical Filament Winding Application

Initially fibers are wet in a resin bath. After the resin bath, fibers are wound around a constant length rotating steel mandrel. Angular winding in a longitudinal direction will provide more strength. With this method, production of consistent size pipes are possible. A polyester based release film is applied on the mandrel and a chemical resistant layer will form the first layer. Continuous fiberglass is applied for structural integrity. These composite materials contain no or less filler. This provides a lighter product but at a higher cost. This type of production is usually preferred for chemical process equipment and pressurized vessels.
