Abstract
The NEMMO Research and Innovation Action project is funded by the European Commission under its Horizon 2020 framework programme. The project was approved under call LC-SC3-RES-11-2018: Building a Low-Carbon, Climate Resilient Future: Secure, Clean and Efficient Energy. This Deliverable 3.4 describes key findings from research carried out to develop novel solutions for enhanced material performance of composite turbine blades for application in tidal stream power conversion. This work is now complete, and the report is intended to summarize key results. An outline of methodologies developed and implemented are presented first. Key test results are then summarized. Three important aspects of composite blade design and construction are addressed in turn in the report following the first three tasks of the Work Package.
