聚四氟乙烯/玻璃纤维胶带在风电叶片制造过程中的应用分析

APPLICATION OF POLYTETRAFLUOROETHYLENE/GLASS FIBER TAPE IN MANUFACTURE OF WIND POWER BLADE

研究了聚四氟乙烯/玻璃纤维胶带作为脱模介质对玻璃钢表面的影响以及对风电叶片制造成本的影响。从接触角、拉剪性能和对不同涂层的附着力这三大方面,对比了分别使用聚四氟乙烯/玻璃纤维胶带、尼龙脱模布、光滑和砂纸打磨这四种方式获得的玻璃钢表面性能。研究结果表明:使用聚四氟乙烯/玻璃纤维胶带获得的玻璃钢表面润湿性一般;玻璃钢使用聚四氟乙烯/玻璃纤维胶带脱模可获得与使用脱模布相当的拉剪性能;使用聚四氟乙烯/玻璃纤维胶带获得的玻璃钢表面涂装附着力与其他方式持平。经济性分析表明国产聚四氟乙烯/玻璃纤维胶带在模具上的应用有望降低风电叶片的制造成本。

The effect of polytetrafluoroethylene/glass fiber tape as a release medium on the surface of FRP and its influence on the manufacturing cost of wind power blades was studied. In this paper,surface performance of glass fiber reinforced plastic（ FRP） obtained from the four methods of polytetrafluoroethylene/glass fiber tape,nylon stripping cloth,smooth and sandpaper grinding were compared with the three aspects of contact angle,tensile shear performance and adhesion to different coatings. The results show that the FBP obtained from polytetrafluoroethylene/glass fiber tapes has ordinary surface wettability. FRP using polytetrafluoroethylene/glass fiber stripping mold can achieve comparable shear performanle with that by the use of stripping cloth. Fiberglass/fiber glass tape obtained from FRP surface coating adhesion flat with other ways. Economic analysis shows that the application of domestic polytetrafluoroethylene/glass fiber tape in the mold is expected to reduce the manufacturing cost of wind power blades.
