Abstract:
This invention is directed to a novel fiberglass pole construction and the method for forming such. The pole is of composite construction and includes inner, outer and intermediate layers resin bonded together into an integral hollow elongated tapered form exhibiting lightweight and high strength characteristics. The intermediate layer includes individual sublayers in turn formed from a plurality of strips of non-woven, unidirectional glass fiber fabric. The strips of each sublayer are circumferentially staggered about the periphery of the pole and are disposed lengthwise therealong so that the orientation of the glass fibers forming such strips is parallel to the longitudinal axis of the pole. Several such sublayers are built up until the necessary strength characteristics have been imparted to the pole. An outer layer of generally spirally wrapped ribbon essentially completes the structure.
