Development of a rotor blade made from renewable raw materials for wind turbines
Brief description
As part of the project, rotor blades for a small wind turbine are to be developed from renewable raw materials in order to show that it is possible to build such rotor blades while meeting all relevant technical requirements. When selecting the plastics and manufacturing processes, the focus is on energy efficiency and sustainability. In the course of the energy transition and the associated expansion of renewable energies, wind turbines are being built and planned in many places. The rotor blades of such turbines are usually manufactured from fiber-reinforced plastic composites. These materials are readily available, have good mechanical material properties and reliably adjustable material characteristics. A major disadvantage, however, is the costly and, in some cases, still unresolved disposal or recycling of the fiber-reinforced plastic composites used. Various research approaches are therefore looking into the use of natural fibers, wood or other renewable raw materials in the construction of rotor blades. From preliminary studies that have already been carried out, the applicants have identified promising material combinations of renewable products and flax fibers that could be suitable for the construction of rotor blades due to their mechanical properties. However, many questions remain unanswered before they can actually be realized. These are to be addressed with the funding.
