ABSTRACT:
An improved fiber/resin composite tapered ski pole shaft and a method for making it. The shaft is hollow and is formed from a fiber/resin composite in which the resin is a thermoplastic material capable of being reheated and reformed. A straight, non-tapered, preformed shaft is heated at the lower end until the thermoplastic resin becomes workable, and then pressure is applied to taper the lower end of the shaft toward the tip. The shaft is held at a constant length during the tapering step such that the displaced thermoplastic material increases the wall thickness of the lower end of the shaft uniformly toward the tip. The rate of taper can be such that the tip becomes solid.
