随着全球潮汐流能源越来越接近商业可行性，开发商努力降低能源平准成本，以挑战与化石燃料发电相关的低成本，因此带来了额外的挑战。本文详细介绍了为用复合材料制造下一代潮汐涡轮机叶片而开发的许多新技术。克服的主要挑战包括厚截面层压板的制造、坚固根部连接的集成设计方法，以及盐水浸泡对玻璃纤维复合材料影响的量化。为了证明所提出的解决方案的弹性，进行了物理测试，并在本文中介绍了一些结果，特别是与盐水浸泡对复合材料的影响和厚截面层压板的制造有关的结果。这些进步将为潮汐涡轮机叶片提供在恶劣环境中生存的最佳机会，并保持 20 多年的设计寿命。
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.
