Abstract
Composite utility pole core systems wherein at least one core member fits within, but is not bonded to, the composite pole. The core systems provide increased bending strength in a hollow composite pole by preventing collapse of the cross section of the pole, the normal precursor to failure in bending of a tubular structure. The core members may be separately manufactured, and used individually or in plurality, being spaced equally along the length of the pole, or spaced unevenly, using closer spacing in the lower regions of the utility pole where bending stress are likely to be the largest.
