The current application status and challenges of pultruded plates of large-tow carbon fiber for wind turbine blades were summarized.The pultruded plates of carbon fiber for wind turbine blades are produced continuously through thermal curing pultrusion molding process using continuous large-tow carbon fiber and high-performance epoxy resin,and are mainly used as the main beam of offshore wind turbine blades.The current challenges of pultruded plates of carbon fiber for wind turbine blades are to improve the performance,including compression performance,interlayer performance and splicing performance,and reduce the production costs.Carbon/glass hybrid pultruded plate,as a low-cost pultruded plate,can provide more possibilities for blade design,weight reduction and cost reduction.It was expected that the application of large-tow carbon fibers would be further en-hanced with the development of offshore wind power and the acceleration of the localization process of large-tow carbon fibers in the wind power field.
