The most modern material used in ski pole production is carbon fiber. A patent has been filed on a biocomposite material that can be used for ski poles, but this design has yet to be manufactured. Axel Composites has a patent for carbon fiber ski poles dating back to 1975, however, inventor David P. Goode's improved design from 1989 became the first widely produced. The carbon fiber pole builds on the same qualities of the aluminum pole: lightness and stiffness while being extremely strong.
