Mechanisms of Solid Particle Erosion Damage to Wind Turbine Blades (GFRP) Irradiated by Ultraviolet Rays

The current focus on renewable energy is driving installation of a growing number wind turbines. In recent years, efforts to improve power generation efficiency by using larger turbine blades have resulted in higher blade tip speeds. glass fiber reinforced plastic (GFRP) used for surfaces subject wear due particle impingement from wind, rain, and dust during long-term operation. As the mechanical effect such impacts, erosion factor failure. addition, exposure operating turbines sunlight leads ultraviolet (UV) degradation, which makes failure more likely accelerating erosion. Addressing this issue requires erosion-resistance measures that take into account effects UV light, but precise nature relationship between degradation mechanisms remains unclear. study, we investigate those reproducing GFRP exposed light an effort lay foundation effective measures. result, clarify decrease interfacial strength resin dominant process accelerates blades.
