composite blade construction

This article explores the critical role of wind turbine blade materials in modern renewable energy, focusing on the advantages of structural PVC foam core. It details how UNION COMPOSITES' StruCell® rigid foam enhances blade performance through sandwich construction, offering superior stiffness-to-weight ratios, low resin absorption, and exceptional fatigue resistance. The post breaks down specific density applications—from aerodynamic shells to load-bearing shear webs—and explains why DNV GL-certified PVC foam is the preferred, durable alternative to traditional balsa wood for high-efficiency offshore and onshore turbines.
