纤维增强塑料拉挤板材对接/搭接弯曲性能研究

Research on the butt/lap bending performance of fiber reinforced plastic pultruded sheet

近几年风电叶片迅速发展,对于叶片材料的性能要求也越来越高。纤维增强塑料拉挤板材(以下简称"拉挤板材")由于其高强高模的特性,被风电行业广泛应用在叶片上[1];而拉挤板材在实际叶片梁帽铺设过程中,会出现搭接的情况,从而满足实际的生产需要;本文着重研究拉挤板材在实际生产过程中不同形式的拉挤板材进行对接/搭接所能承受的弯曲性能,并进行比对分析,从而对叶片设计分析以及实际生产提供数据支持。

In recent years,wind power blades have developed rapidly,and the performance requirements for blade materials have become higher and higher.Fiber-reinforced plastic pultruded sheet (hereinafter referred to as pultruded sheet) is widely used on blades by the wind power industry due to its high-strength and high-modulus characteristics.In the actual laying process of pultruded boards,there will be overlaps.In order to meet the actual production needs,this paper focuses on the bending performance of the pultruded sheet under different conditions in the actual production process,and compares and analyzes it,so as to provide data support for the blade design analysis and actual production.
