Leading wind turbine OEM’s resin uptake analysis on a 6,500kg hybrid core blade shows AIREX SealX significantly reduces the cost and time vs. standard PET foam core.

The resin uptake analysis was conducted in a real production of a 6,500kg hybrid core blade, where AIREX SealX and standard PET foam core were compared in shear web and shell infusion. The blade total core was 151m2 and weighted 342kg, the shear web was 100% PET core, and the shells hybrid.

With AIREX® T92.100 SealX the total resin saving was more than 3%, equivalent to 57kg less weight in comparison with the standard PET core – T92.100 SealX was applied in 57m2 and saved 1kg/m2; the core weight reduction was 29%; and the coating surface savings in total $3/m2. The total blade weight saving was 1%. Furthermore, the infusion time was even reduced due to the resin saving and resin flow speed over the AIREX® T92.100 SealX surface.

Eric Gauthier, president of global key accounts at 3A Composites Core Materials said: “AIREX® T92 SealX is much more cost-effective than standard PET or PVC foam cores for wind turbine blade infusion. With AIREX® T92 SealX we can bring increasing savings to our wind customers”.

About AIREX® T92 SealX – setting new standards in resin uptake and total cost control

AIREX® T92 Sealhas been extensively tested and proven. T92 SealX is used in wind turbine blades, boats, automotive applications to name just a few. In all applications SealX proves its weight and cost saving potential and it is easy to use. With the dramatic reduction of resin uptake, the core-skin adhesion was a prime focus. Despite the reduced resin uptake, AIREX® T92 SealX features the same excellent skin adhesion as any conventional PET core material. Furthermore, all mechanical properties of the core – including fatigue resistance – are unaffected by the new SealX technology.
