<p>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/or as part of the wall inside and/or outside portion. The pole can include an outside surface resistant to ultra violet radiation.; Poles of this invention can be formed using a continuous process on a rotating mandrel, making use of differently positioned stations to form the different portions of the pole as the fabrication is moved axially along the mandrel.</p> |
