With the development of large-scale and lightweight blades,as well as the reduction of the electricity cost of wind turbine units,100-meter blades have become the mainstream product in the wind power market,which puts higher demands on the composite materials used in the manufacturing of wind turbine blades.The performance of various polymer foam core materials for 100-meter wind turbine blades is discussed.The microstructure,chemical composition and mechanical properties of three typical polymer foam core materials,as well as the mechanical properties of core materials after resin injection are studied.
