Rod - Rectangle/Strip - Pultruded Unidirectional - High Modulus - 0.024 x 0.237 x 78 Inch- BLOWOUT

The pultrusion process shows great similarities with the extrusion of e.g. aluminium and thermoplastic plastics. However, instead of injection moulding the plastic material, the pultrusion process continuously pulls fibres 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. Polymerisation 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 pultrusion process guarantees an accurate design and measurement control, perfectly aligned fibres and a smooth surface. The technology is suitable for all types of fibres or a combination of fibre types. A high fibre-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.
