Pultrusion and Pullwinding Processes

PultrusionPultrusion is a fabrication technique for making continuous profiles of composite materials. As with all composites the material is made in the same time as the final product. Pultrusion is based on fibres that are impregnated with a thermosetting resin and pulled through a heated die where curing takes place. Different laminate lay-ups are possible with reinforcements of mats, fabrics and multi-axials. The finished profiles are cut to length by a saw at the end of the line.

PullwindingPullwinding is a further developed version of pultrusion where winders wind fiber in the crosswise direction during the pultrusion process. This gives better performance than other crosswise reinforcement as mats and fabrics.
