Additional incremental mandrels and additional layers of continuous, resin-impregnated filament reinforcement are successively wound as desired. Preferably all windings occurs prior to the curing of any previous winding. The ends of the mandrels and any cross winding across these ends form stabilizing members within the poles to counteract against compressive forces. The pole has a smooth outer surface when the additional mandrels are properly sized to mate with the wound ends of the previous adjacent mandrel.

This enables both inner and main layers to be brought together at a time when the interface between them is molten. A tie layer can be employed, when desirable, to enable the layers to be combined without melting the layer interface.
