Partners from the WALiD consortium attended the final meeting on 12th January 2017 at Smithers Rapra in Shropshire.
The purpose of this meeting was to allow the partners to present an overview of work performed and results achieved throughout the projects’ 4 years.
The meeting was very successful and was attended by the EC Project Technical Advisor who commented how much he has enjoyed being a part of the WALiD project and how welcome he has been made to feel by the partners.
The day was rounded off with a tour of the various laboratories at Smithers Rapra.
WALiD, the European project to introduce thermoplastic materials in offshore rotor blades, has successfully demonstrated that replacing thermosets in the blade root, shear web, spar cap and coating can lead to a lighter, cost-efficient and recyclable blade.
Offshore wind turbines are becoming ever larger and the transportation, installation, disassembly and disposal of these blades are presenting the industry with new challenges. To meet this challenge, European researchers and industry experts partnered to develop highly durable thermoplastic foams and composites, a thermoplastic coating with high erosion and UV resistance and an innovative automated fibre placement process for layup of hybrid fibre tapes resulting in a lighter blade with an improved design and an increase in service life.
Sandwich materials made from thermoplastic foams and fibre-reinforced plastics are used for the outer shell of the blade as well as for segments of the inner supporting structure. The carbon-fibre reinforced thermoplastics are used for areas of the blade that bear the greatest load, whilst glass-fibre reinforces the less stressed areas. The introduction of a modular designed shear web and new ultralight, stiff materials with increased mechanical properties make it quick to manufacture and cost-effective to produce.
The WALiD thermoplastic coating is a protective surface layer that has demonstrated increased durability under harsh conditions. In addition, to support the development of the coatings a new predictive model was validated to model the relationship between surface properties and erosion resistance.
The research leading to these results has received funding from the European Union’s Seventh Framework Programme (FP7/2007-2013) under grant agreement no. FP7-309985.
A final press release describing the technology developed within the project.
The fifth issue of the project newsletter including a partner’s feature on Windrad and highlights of Offshore Energy16.
The WALiD partners recently exhibited at the Offshore Energy event which took place on 25th and 26th October in Amsterdam. This event was the ideal opportunity to showcase the results achieved in the project, display the demonstrator and other materials developed and highlight the key benefits.
A series of interviews took place during the conference at the Offshore Wind Expertise Hub and Hans Knudsen from Comfil was invited to speak about WALiD. During this interview, he outlined the advantages of the WALiD blade and explained the use of thermoplastics and end of life approach in the project.

The ‘K’ fair is held every three years in Dusseldorf, Germany and is the world’s leading fair for the plastics and rubber industry. This year’s fair took place from the 19th to 26th October and was attended by Fraunhofer ICT.
Fraunhofer ICT displayed a range of material from their stand which included sandwich, tape and foam samples and project literature was also distributed. Around 218,000 visitors attended from 108 countries from a variety of sectors, both professional and public. Approximately 30 people expressed an interest in the project.
ITHEC 2016 was the third International Conference and Exhibition on Thermoplastic Composites. International experts and representatives were invited from leading companies to highlight the opportunities that thermoplastic composites are able to offer in terms of cost, performance and lead times.
This year’s conference took place from 11th to 12th October in Bremen, Germany and was attended by Fraunhofer ICT who were invited to give a paper and a presentation of the project.
Around 280 people attended this conference from a total of 26 countries, a high proportion of which were from industry.
The world’s leading exposition for wind energy provided the perfect platform for project partner Windrad Engineering to disseminate the project.
This event, which took place in Hamburg, Germany between 27th to 30th September attracted around 35,000 visitors from fields such as suppliers, manufacturers and material development and processing.
Windrad disseminated the project by handing out project flyers and taking part in technical discussions.

Press Release FINAL
Michael Haenler gave a lecture explaining the basic ideas of the project at the 14th Windmesse Symposium which took place on 12th May 2016 at the Hamburg Port Hotel in Germany.
The lecture, entitled “New Materials for Offshore Blades: The WALiD Project” was attended by approximately 50 people from areas such as research, suppliers, manufacturers, certifiers, facility managers and companies responsible for the development of offshore windfarms
