Pultrusion

Pultrusion 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 fibers 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 multiaxials. The finished profiles are cut to length by a saw at the end of the line.
