**4. Conclusions**

The main purpose of this study was to provide the production of an innovative wind turbine blade with a new perspective. This new point of view is to compare the turbine blade structure to the reinforced concrete beam structure, which is frequently used in construction technology. Just as concrete is used as a matrix material in reinforced concrete beams and steel bars are used for reinforcing material, it is also possible to strengthen the recyclable light plastic matrix material in turbine blades with the help of carbon or glass bars. The use of recyclable materials in the production of this turbine blade also makes this new production technique more environmentally friendly. In addition, the fact that the amount of epoxy or resin used in traditional turbine blades is considerably higher than the trace amount of epoxy material used in the production of the new generation blade, emphasizes the importance of this new production.

In order to explain to the energy sector that the new generation turbine blade technology can be functional, it was compared with the commercial turbine blade of the same size and profile. Experimental DIC tests were applied for these comparisons and it can be seen that the new generation blade was stiffer. In addition, a simple modeling approach for both the commercial and the new generation blades is also presented in this study in order to attract the attention of the energy industry. In addition, the models of both blades were used with flow analysis and their behaviors at different speeds and different angles of attack were determined. All these findings demonstrate that the new generation blade has the possibility to exhibit sufficient strength in the field.
