摘　　要：随着叶片设计技术的突破,玻璃纤维拉挤板主梁替代传统玻璃纤维布主梁在大型陆上和超大型海上叶片中应用。玻纤拉挤板生产过程中,浸胶工艺和预成型之间存在树脂回流现象,为验证回流拉挤树脂对玻璃纤维拉挤板性能的影响,研究树脂理化性能变化和玻璃纤维拉挤板本体结合性能。结果表明,回流树脂较新树脂黏度大、凝胶时间较新树脂凝胶时间短,加入新树脂后,黏度降低,凝胶时间延长,并不影响使用;此外,虽然回流树脂的理化性能较新树脂有变化,但其拉挤板本体结合性能与新树脂拉挤板的本体结合性能持平,未见降低,可满足生产应用。With the breakthrough of blade design technology,fiberglass pultruded plate main beams have replaced traditional fiberglass cloth main beams and are applied on large onshore and ultra large offshore blades.During the production process of fiberglass pultruded plates,there is a phenomenon of resin reflux between the impregnation process and the preforming process.In order to verify the effect of reflux resin on the performance of fiberglass pultruded plates,the changes in the physicochemical properties of the resin and the bonding performance of the fiberglass pultruded plate body were studied.The results show that the viscosity of the reflux resin is higher than that of the new resin,and the gel time is shorter than that of the new resin gel,but after adding the new resin,the viscosity decreases and the gel time is longer,which does not affect the use.In addition,although the physicochemical properties of the reflux resin are different from those of the new resin,the bonding performance of its pultruded board body is the same as that of the new resin,and there is no decrease,which meets the production application requirements.
