Offshore wind turbine blade materials
With regards to the state-of-the-art wind turbines (three-bladed upwind turbines of increasing size), various developments can be identified, such as inclusion of lighter materials (to decrease gravitational fatigue loading), and the application of stiffer materials and structures (to keep the blade from hitting the tower at high winds).

In this study, we assess the primary raw material demand and secondary material supply of global OWE. It includes a wide assortment of materials, including bulk materials, rare earth elements, key metals, and other materials for manufacturing offshore wind turbines and foundations.
A short overview of composite materials for wind turbine applications is presented here. Requirements toward the wind turbine materials, loads, as well as available materials are reviewed.
Blades. Turbine blades can reach speeds of up to 180mph at their tip and are subject to immense aerodynamic, inertial, and gyroscopic loads. They must therefore be made from stiff and lightweight materials resistant to high-cycle fatigue.
