CFRP Profiles Pultrusion Process

The pultruded process continuously pulls fibers from rolls, which are then wetted with a matrix material (usually a thermosetting resin like epoxy resin). Subsequently, they are pulled through a heated die, which determines the shape of the profile. Polymerization of the resin takes place in the die, forming a rigid profile with a diameter corresponding to that of the die and a length that is endless, in theory. The extruded process guarantees an accurate design and measurement control, perfectly aligned fibers and a smooth surface. The technology is suitable for all types of fibers or a combination of fiber types. High fiber-volume content is feasible, which makes it possible to reach a high specific rigidity and strength of the profiles. The serial character and the controllability of the process ensure a good price/quality ratio.
