Together with the ribs, the two spar caps in the rotor blade shells are, one might say, the skeleton of each and every rotor blade of a wind turbine. They must be able to withstand very high loads for the operational life of the turbine. Therefore it is essential to deliver high component quality and to ensure that the best possible properties of the mix of fibres and matrix are achieved.
We offer you Pulcap® pultruded profiles for spar caps with
Our Pulcap® profiles are manufactured using the pultrusion process. The continuous process enables the manufacture of almost endless profiles with a consistently high quality. In the pultrusion process, reinforcement fibres are pulled very straight in tension, which largely reduces the occurrence of fibre undulations and therefore inconsistency in fibre orientation that frequently occurs in other manufacturing processes.
Pulcap® pultruded profiles for spar caps are also available with a peel ply on request,
so no need to roughen the surface, e. g. by sand blasting, before fitting the profiles.
