Poles of this invention have an annular body with a wall structure comprising a number of fiber reinforced resin layers, which can be positioned to form an inside and/or outside portion of the wall structure. A portion of the layers are oriented longitudinally within the wall structure, and the wall structure also includes radially-oriented fiber reinforced resin layers. The pole includes one or more layers or a core of a composite material or polymer mortar disposed within one or more locations of the wall structure, e.g., as an intermediate layer and/o...
1. A method for making a fiber reinforced resin pole having an annular body defined by a wall structure, the method comprising the steps of: forming an inside wall structure of the pole by depositing a number of fiber reinforced resin layers onto a rotating mandrel, wherein a portion of the fiber reinforced resin layers are oriented longitudinally along a length of the pole and parallel to an axis of the mandrel;depositing a polymer mortar material onto the inside wall structure to form a pole intermediate core, wherein the polymer mortar material compri...
