Rod - Pultruded Unidirectional - 0.039 x 78 Inch

Pultruded unidirectional rods are manufactured through a pultrusion process. This solid carbon fiber rod is 0.039” diameter and 78” long. Because the fiber orientation this rod provides strength and rigidity along the axis of rod. Pultruded rod is great for reinforcing structures. The pultrusion process guarantees an accurate design and measurement control, perfectly aligned fibers and a smooth surface.

The pultrusion process shows great similarities with the extrusion of e.g. aluminum and thermoplastic plastics. However, instead of injection molding the plastic material, the pultrusion 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. 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 technology is suitable for all types of fibers or a combination of fiber types. A 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.
