Production Processes

Goodwinds Composites manufactures our tubes in one of three ways: pultrusion, roll-wrapping, and filament winding.  We describe each of these processes in greater detail on the pages you’ll find by clicking each of the buttons to the right.

“Composite Resources has been working with Goodwinds Composites for almost a decade.  The service and products we have received have been stellar!  Paul de Bakker has always been quick to respond, happy to assist, and genuinely a pleasure to work with.  Goodwinds Composites is highly recommended!”

pultrusion

Pultrusion

Pultrusion is a process in which dry, continuous fibers are pulled through a bath of resin and then through a die. The die serves two purposes: it forces the bundle of wet fibers to conform to the shape you want to create and, since the die is heated, it will cure the resin to set the bundle of fibers into its final shape.

Roll Wrapping

Goodwinds Composites precision builds custom wrapped carbon and fiberglass tubes. Roll-wrapping involves the applying of resin pre-impregnated fiber cloth (pre-preg) around a mandrel. The outer diameter of the mandrel determines the inner diameter of the final tube.

Filament Winding

Filament winding is a process in which a pre-programmed robot arm applies a bundle of resin-impregnated fibers onto a spinning mandrel.  After the desired layup has been finished, the mandrel is placed in an oven to cure. After the curing process, the mandrel is removed, leaving a filament wound, hollow tube.
