Kevlar fibers have a very high tensile strength, but carbon fibers in an epoxy or thermoplastic matrix are much stiffer. This means you can make a much lighter boat for a given stiffness. Kevlar is also weakened by exposure to UV. As noted, the lightest and strongest race cars and military jets are made from carbon fiber. -- mike -------------------------- Michael Edelman http://foldingkayaks.org http://findascope.com *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
