摘　　要：随着风电叶片的大型化,对复合材料性能的要求越来越高。近年来,拉挤复合材料在风电叶片上成功应用,这是风电叶片制造工艺几十年发展历程的一个新的里程碑。拉挤复合材料具有更高的力学性能与生产效率及更低的制造成本,在制造风电叶片主承力梁帽时,拉挤工艺几乎完全取代了使用了20多年的真空灌注工艺。为了梳理风电领域拉挤复合材料的研究进展,本文从拉挤板用原材料、拉挤板力学性能、拉挤板缺陷检测技术以及拉挤板梁帽灌注工艺方面综述了风电领域拉挤复合材料的专利申请与研究进展,旨在为复合材料与叶片领域后续研究提供参考。The increasing size of wind turbine blades puts forward higher and higher requirements on the performance of composite materials.In recent years,the successful application of pultruded composite materials has been a milestone in the development of decades-long wind turbine blade manufacturing technology.With higher mechanical properties of end-products,higher production efficiency,and lower manufacturing costs,pultrusion process almost completely replaces the vacuum infusion process that has been used for more than 20 years to manufacture the main bearing spar cap of wind turbine blades.In order to sort out the research advances of pultruded composite materials in wind turbines blades and shed lights on future research for engineers and scholars in the field of composite materials in wind turbine blades,this paper summarizes the technical development and patent application from the aspects of raw materials for pultruded plates,mechanical properties of pultruded plates,pultrusion process parameters for infusion technology and defect detection method of pultruded blade spar caps.
