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.
Knowledge Centre WMC performed the full scale testing program for the certification of the EWT29 rotor blade for wind turbine manufacturer EWT. As part of the blade test program, the flapwise fatigue test was performed at the first flapwise resonance frequency of the blade (see video). Both the range and average of the bending moment distribution are controlled during the test by using two hydraulic actuators. The rotor blade is used in the EWT DW61 direct drive wind turbine with a rotor diameter of 61 m For more information about this wind turbine please visit the website from EWT.
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.
