Abstract:
In recent years, much attention has been paid to wind energy and the expansion of wind farms to replace fossil fuels with this energy source. Wind turbine blades are currently made of composite materials using thermoset matrices. These materials are not recyclable, and it is impossible to return their resins or fibers to the production cycle. In this research, an attempt has been made to replace thermoset resins with thermoplastic materials that can be recycled. In the following, manufacturing and performance aspects of thermoplastic resins have been examined, and the optimal material has been selected using the modified fuzzy logic method (MFLM). In this study, reactive processing of polyamide 6 is identified as the best available option for manufacturing thermoplastic matrix composites. Next, the vacuum infusion process (VIP) of polyamide 6 is investigated using software simulations. Finally, the optimal injection network of this resin for wind turbine blade mold is presented. This study shows that polyamide 6 can be transferred into the mold in an acceptable filling time and without the occurrence of process problems such as dry spots
