Assessing the fatigue of fibre-reinforced plastic composites using the example of rotor blades

Fibre-reinforced plastic composites have established themselves as lightweight construction materials for wind turbine rotor blades. However, understanding of their fatigue behaviour is still limited. EUROS performs research into this fatigue behaviour and hence into the thresholds of operationally reliable construction.

High Material Efficiency as Goal

Fibre-reinforced plastic composites (FRCs) have been used for manufacturing wind turbine rotors since 1957 and have established themselves as lightweight construction materials in this field. A virtually unlimited range of design possibilities, a high elastic modulus, high stability and low densities qualify these materials for the application in question. Fibre-reinforced plastic composites are also being deployed in a number of other areas, in particular in the field of mobility. Increasing use across a wide range of applications results in cost pressure pushing material utilisation to its physical limits. The efficiency of the FRCs...
