Abstract
Fiber reinforced plastics are drawing significant attention to the renewable energy sectors in terms of their excellent specific strength, modulus and stiffness properties as well as outstanding processability, corrosion, and chemical resistance. Wind turbine blades, which inherent GFRP main bodies, are the representative practice for generating renewable energy. While the wind turbine blades may inevitably be damaged due to the harsh service environments like low temperature, acidic moisture, and intense UV irradiation. Remediations on a damaged wind turbine are indispensable to preserve the integrity, guarantee the strength, and expanse the service life. The photo polymerizable resins are featured by less energy consumption, equipment requirement and curing time compared to conventional thermal polymerizable resins. During this dissertation, the photo polymerizable resins were employed to conduct patch remediation on pre-damaged GFRP specimens. The stress and damage distributions of repaired GFRP specimens were obtained through numerical/experimental assessments to validate the remediation feasibility; properties in low temperature were investigated, which was in consideration of the relative cold service environment; durability of repaired GFRP specimens in long-term UV and acid ageing were evaluated to represent the typical service environments of wind turbine blades.
