Large wind turbine blades are the core components of wind turbines.Carbon fiber has the advantage of low density and high strength,and is gradually replacing traditional glass fiber composite materials as the main material for the manufacturing of large wind turbine blades.The life cycle carbon emissions of wind turbine blades mainly come from raw materials in the production process.It is estimated that after using carbon fiber instead of glass fiber as the main material of wind turbine blades,the carbon fiber consumption of mainstream 4 MW and 6 MW wind turbine blades reaches 12~18 tons,the carbon emissions caused by the use of raw materials reach 240~360 tons,and the overall weight reduction of wind turbine blades is 15%~20%,which is expected to reduce the carbon emissions of the life cycle of wind power generation.
