Abstract
Abstract A strong, lightweight, flexible ski pole and a method for making it. The ski pole comprises a filament-reinforced, resin-matrix composite shaft with anti-splinter material to prevent filament splinters from protruding from the outer surface of the shaft. In one embodiment, the shaft comprises a filament-reinforced, resin-matrix composite hollow outer shaft continuously integrally pultruded about a core member. In another embodiment of the invention, the shaft comprises a filament-reinforced, resin-matrix solid pultruded body. In both embodiments, a polyester veil is wrapped around the filaments within the resin matrix to prevent filament splinters from protruding from the outer surface of the ski pole shaft. Cut lengths of the ski pole shaft are fitted with a basket adaptor, a basket, a tip and a grip to make a finished ski pole.
