Fiberglass is widely used in the manufacturing of wind turbine blades because it can provide excellent strength to weight ratio and cost-effectiveness.The aim of this study is to further enhance the application performance of glass fiber reinforced composite materials in wind turbine blades through optimized design,in order to extend service life and improve energy capture efficiency.Research has confirmed that by finely controlling the interface between glass fiber and resin,combined with comprehensive optimization of structural design,the performance of wind turbine blades can be significantly improved.These improvements not only improve the structural efficiency and durability of the blades,but also provide new ways to improve wind power generation efficiency and reduce manufacturing costs by reducing blade weight.Future work will focus on long-term performance validation in practical operating environments,as well as further cost-benefit analysis.
