NACELLES & SPINNERS

Designed for the future of wind energy

Next-gen nacelles and spinners built with Diab’s high-performance core materials.

In modern wind turbines, nacelles and spinners are more than covers; they’re essential to protecting critical systems and optimizing aerodynamics. To meet demanding cost and performance targets, many manufacturers rely on sandwich composite technology. At the core of these solutions, literally and figuratively, is Diab.

For non-structural nacelle applications, where the goal is to create a weatherproof, aerodynamic housing at the lowest possible cost, Diab offers lightweight PET and PVC core materials in low densities. For more advanced structural nacelle designs, often sharing properties with blade construction, we provide higher-grade solutions that can meet tougher strength and stiffness demands.

What sets Diab apart is our ability to enhance both design and production. Our finished and kitted cores, perforated, grooved, and precision-cut, help streamline the resin infusion process. This results in faster cycle times, reduced resin consumption, and more consistent product quality. These processing benefits significantly lower the total cost of production while maintaining excellent structural performance and design freedom.

With a comprehensive offering of core materials, finishing, and complete kitting services, Diab supports OEMs and nacelle manufacturers in building lighter, smarter, and more cost-effective nacelle and spinner systems, ensuring their turbines perform optimally from base to blade tip.
