ECN, together with partners WMC, TRES4 B.V. and GE Global Research will kick off a new R&D project to enable more accurate designs of wind turbine blades by improved modelling and validation of torsional flexibility (which is the twisting of the blade). The VaStBlades project will deliver datasets with unique validation data, an improved structural blade model, validated aeroelastic and structural tools and a 10MW wind turbine blade design.
During the 17th European Conference on Composite Materials (ECCM17) in Munich, from 26 to 30 June 2016, WMC was represented by three members of its material research team.
Iuri Rocha presented a combined experimental/numerical approach used to investigate the effect of water ingression in glass/epoxy composites.
Sibrand Raijmaekers presented research on the relation between temperature and physical ageing of an epoxy material as commonly used in wind turbine blades.
Jagadeesh presented a novel method to use infrared thermography technique for the quantitative analysis of delamination area in composites under fatigue loading.
WMC has conducted tests of full-scale wind turbine blade sections loaded with an edgewise moment. The aim of the tests was to evaluate trailing edge buckling due to an edgewise moment and verify a characteristic blade failure mode such as the trailing edge adhesive joint delamination.
Read the brochure for more information and watch the test video. The work has been carried out in the framework of FP7 IRPWIND.
Early this year a small joint industry project was conducted on the evaluation of embedded composite-steel insert connections. These innovative 'hybrid' connections consist of a steel plate, potentially with spikes added for additional locking, embedded in a composite. A potential benefit of this configuration is that e.g. composite ship skin panels can be joined using standard welding. The goal of this evaluation project was to investigate the influence of welding-induced heat on the composite-steel connection.
WMC has developed the procedures for blade tests since 1984 and has tested many blades for many of the largest blade manufacturers ever since.
FOCUS6 is the integrated modular tool to design wind turbines and wind turbine components like rotor blades. For more than a decade, FOCUS6 is being used by the international wind turbine industry.
