STUDY ON THE PROPERTIES OF FIBER REINFORCNED POLYMERS (FRP) USED IN THE POWER TRANSMISSION POLES --INFLUENCES OF THE RESIN SYSTEMS ON THE PROPERTIES OF FRP

Abstract

Abstract: According to the essential requirements on the fiber reinforced polymer materials (FRP) used in the power transmission poles or towers, two kinds of FRP materials based on polyurethane resins (vinyl modified polyurethane resin, VPU & two-component polyurethane, TPU) were studied. Simultaneously, FRP material prepared by high-functional epoxy resin was tested as a comparison (all samples were prepared by pultrusion method). EP-FRP material exhibited the best mechanical and electrical insulation properties, but its UV aging resistance and the fire resistance properties were limited. Therefore, it cannot be used directly in the outdoor environments. The insulation, corrosion resistance and aging resistance behaviors of VPU-FRP material were good enough. Also, it had the best hydrophobicity. However, the transverse properties of VPU-FRP should be improved further. The combination properties of TPU-FRP materials turned to have better properties, which was the suitable material for the power transmission poles.

Key words: power transmission pole, fiber reinforced polymer (FRP), pultrusion, electric insulation, aging resistance
