| heal.abstract | The increasing demand for reducing carbon dioxide emissions is accelerating the transitiontoward green energy sources such as wind power, with particular emphasis on offshore windfarms. This shift necessitates the development of composite materials that exhibit enhanced durability and environmental resistance. This thesis investigates the development of advanced glass-fiber-reinforced polymer (GFRP) composites through the nanomodification of epoxy matrices using carbon-based nanofillers, specifically graphene nanoplatelets (GNPs) and multi-walled carbon nanotubes (CNTs). These nanomaterials were selected for their ability to simultaneously improve the mechanical, electrical, and moisture-barrier properties of epoxy systems. A holistic experimental methodology was implemented with industrial scalability as a guiding criterion. High-shear mixing was chosen as the dispersion method, and the resulting nanomodified matrices were evaluated through dynamic mechanical analysis, impedance spectroscopy, fracture-toughness testing, and environmental aging. The most promising formulations were subsequently integrated into GFRP composites and tested under simulated operational conditions representative of wind turbine blades. To ensure compatibility with industrial manufacturing, processing considerations, including viscosity control and overall manufacturability, were thoroughly examined. Following laboratory-scale evaluation, the findings were validated using industrially manufactured GFRP and CFRP laminates. This research presents a scalable path for producing high-performance, hybrid-reinforced composites. Importantly, the developed material system demonstrated the necessary properties and processing characteristics required for implementation in a structural component of a wind turbine blade, contributing meaningfully to the long-term sustainability and reliability of wind-energy infrastructure. | en |
