I have placed a discussion on fluid friction on my web site http://home.ican.net/~735769/shape.htm ) so won't take up space here repeating it. As for carbon filled resin being more abrasion resistant I have seen no test reports to support that. My experience suggests that the resin hardness contributes more to abrasion resistance unless one uses a really hard filler like metal powder etc. Cheers, John Winters Redwing Designs Specialists in Human Powered Watercraft http://home.ican.net/~735769/ *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************Received on Mon Nov 09 1998 - 03:44:05 PST
