Abstract / Description of output

As the global tidal stream energy moves closer to commercial viability, additional challenges are presented as developers strive to lower the levelised cost of energy in order to challenge the low cost associated with generating energy from fossil fuels. This paper details a number of novel techniques that have been developed in order to manufacture the next generation of tidal turbine blades from composite materials. The main challenges that are overcome include the manufacture of thick section laminates, an integrated design approach for a robust root connection, and a quantification of the effect of saltwater immersion on the glass fibre composite. In order to prove the resilience of the proposed solutions, physical testing has been performed and some of the results are presented in this paper, particularly in relation to the effect of saltwater immersion on the composite material and the manufacture of thick section
laminates. These advances will give tidal turbine blades the best chance of surviving the harsh environment presented, along with maintaining a design life of 20+ years.
