Abstract :
FRP has been used much for core materials of insulator. FRP consists of fiber and plastics (resin and binder). The fiber contributes strength to FRP. The fiber orientation in FRP has a great effect on the strength of FRP because the strength of FRP mainly depends on the strength of fiber. The direction of applied stress of FRP is different from the kinds of insulators. In this study, inner part of FRP rod was made unidirectionally by pultrusion method and outer part of FRP rod was made by filament winding method. Compressive strength and stress of FRP rods were simulated according to the winding orientation of glass fiber. Simulated value and real evaluated compressive strength were compared each other.
