Middlefart, Denmark -- BASF and Fiberline Composites will be showing a pultruded part made from Elastocoat C6226-100 polyurethane resin, at the upcoming Composites Europe event, BASF said in a press release.
BASF said it has worked Middlefart-based Fiberline Composites to develop this resin to make pultruded rods which can then securely attach the rotor blade root to the nacelle.
BASF added that the continuous pultrusion process permits better alignment of the fibers as well as in-line integration of a metal bushing. This helps to ensure consistent product quality. The polyurethane resin ensures improved adhesion to the metal bushing and also to the epoxy infusion resin.
The pre-manufactured part is designed to remove the need for side-ways drilling to fix the bushings. This makes the blade root and hub diameter smaller and saves a substantial amount of material, said BASF.
Composites Europe is being held at the Messe Stuttgart 17-19 September
