Wind energy is generally considered to be the most promising renewable energy source. In order to improve the technological and economic efficiency, the blade length has to be increased. However, a major challenge is the total weight of the blades, which limits this enlargement.
The four-year European-funded project WALiD, which started in 2013, combines process, material and design innovations in an integrated approach. The core innovation is the use of advanced thermoplastic composites. This creates cost-efficient, lightweight, durable and recyclable blades with a beneficial weight/performance ratio, making wind energy more affordable and competitive. WALiD will introduce a holistic concept focusing on the areas of blade root, tip, shell core, spar and coating in an automated production process. The current material developments in thermoplastic composites, foams and sandwich parts are described in the present paper.
