Filament composite winding

Plastic forming process where multiple lengths of wire is wound around a template, and where the polymer solution is applied either before or after winding.

Beskrivning
Illustration of Filament composite winding

The process

A woven fiber [1] is pulled continuously through a solution vessel [2] to be dipped in a dissolved polymer and curing agent. The fabric is then wound onto a form template [3] that rotates and translates alternately in the axial direction.

After winding the solution is allowed to harden before the core is removed and then the hollow part removed.

In some winding processes the solution is supplied after the fiber web is wound.

Advantages and disadvantages
In comparison with alternative methods
Long fibers, composites with high fiber content can be produced
low material costs, low labor
Precise control of fiber-angle
The need for complex or expensive form
Hard to wrap reverse curvature
Difficult to place the fiber along the product
poor surface finish
