Pultruded products perform incredibly well in bending and tension (pulling) applications since all the fibers are oriented along the length of the tube (or rod). They do not however perform well in other loading scenarios such as torque and crushing. These parts are made by pulled fibers through a shaped die while simultaneously injected with resin to create the required profile. We do not recommend pultruded tubing or rod in applications such as drone or UAV motor (boom) arms.

Pultruded products are made with the process of pultrusion. If you are not familiar with the pultrusion process, it shares similarities with the extrusion of e.g. aluminium 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).

Then, 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:

  • Accurate design
  • measurement control
  • perfectly aligned fibres
  • smooth surface.
