Research Progress on Polyurethane Wind Turbine Blade Materials and Process Applications
The differences in mechanical properties and process characteristics of polyurethane and epoxy resin used in wind turbine blades were compared.The research progress of other types of main materials in polyurethane blades was analyzed,including the mechanical and fatigue properties of polyurethane glass fiber composite materials.The verification and application of polyurethane matching with other main materials such as core materials,structural adhesives for blades were introduced.The analysis and research of polyurethane resin in blade forming process and some defects were conducted,and some process control suggestions were proposed to provide necessary basis for the replacement application of blade materials.
