ABSTRACT:
A novel tubular composite structure for transmitting substantial forces comprising a metal tubular core having a layer of structural metal adhesive on the exterior thereof. On top of the structural adhesive layer are alternating laminae of resin impregnated unidirectional reinforcing fibers and of woven fiberglass, beginning with a layer of woven fiberglass followed by a lamina of resin impregnated unidirectional reinforcing fibers and continuing in alternating fashion but ending with a final layer of resin impregnated continuous unidirectional reinforcing fibers. All fibers are disposed at a predetermined angle of orientation with respect to the longitudinal axis of the tube. The number of layers disposed along the length of the tubular core varies such that the core thickness along the length of the tubular shaft has its greatest thickness at the mid section of the shaft.
