Why do OEMs increasingly specify PET for new blade designs?
Consistency, recyclability, broad availability, and good mechanical performance.
How do offshore conditions affect foam selection?
Offshore environments require moisture-resistant, fatigue-tolerant foam cores.
What adhesive films are used with foam in prepreg blades?
Epoxy film adhesives designed for high peel and shear
Which foam type is most cost-effective for wind blades?
PET foam generally offers the best cost-performance ratio.
What is the role of core materials in trailing edge reinforcement?
They provide thickness and stiffness to prevent flutter and[…]
Are recycled PET foams suitable for structural sections?
Yes. Modern recycled PET foams meet or exceed mechanical
How does blade length affect core material selection?
Longer blades require higher-strength cores with superior fatigue resistance.
