MEL Composites was a pioneer in Spain in the application of sandwich structures in wind turbine blades and nacelles. Composite materials have proved to be highly resistant to atmospheric conditions, requiring minimal maintenance during the life of the turbines (typically more than 25 years).

The nacelles of the latest generation turbines are self-supporting structures; and the use of sandwich constructions reduces transport and installation costs whilst also providing a high level of thermal and acoustic insulation.

Foam sandwich blade construction delivers a series of benefits; from a significant reduction in weight to greater efficiency in the production processes by being able to use the core as a flow medium for the resin during infusion. All of these advantages deliver a significant reduction in manufacturing costs compared to other similar systems.
