Aerodynamics is a very important aspect of wind turbines, the hub, being one of the most exposed elements together with the blades and made of cast steel, needs to be protected and ensure that it does not distort the airflow. To do this, the hub is covered with components made of GFRP, normally in 3 pieces, following the same process as the shells. The excellent properties of GFRP allows to insulate and protect the components of wind turbines to extend their useful life beyond 20 years.
