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

Abstract

Abstract: 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.
