Hello Gardner   Why do you assume that it can't bend like fiberglass ?  You should not assume but make test of section you plan to build.  I would  expect it would bend just like fiberglass but possibly slightly stiffer.   The price on the E bay carbon tow is way too high !   Take a look at ; http://www.solarcomposites.com/composites/compositespools.html   It is only $18 /lb.  The E-bay is $68 for 1.6 lb.($42./lb)   It may be easier to work with if you used Uni carbon tow and carbon cloth but if you are building elementary just purchase plans and go with what Rob recommends.  That is what you are paying him for, his experience!     As I recall I only paid around $15/lb.for some I purchased a your or two ago.though a purchase that Rob organized directly  from Zoltek when they wore a sponsor of his  Solitary and he had plans to race it that never materialized.   Happy sailing, George Kuck Chestertown, Md. --- On Sat, 3/6/10, Gardner Pomper <gardner@networknow.org> wrote: From: Gardner Pomper <gardner@networknow.org> Subject: [harryproa] Carbon tow? To: harryproa@yahoogroups.com.au Date: Saturday, March 6, 2010, 9:06 PM   Hi, Can you post again what sort of thing I should be looking for in carbon fiber tow? Is there a simple term that I need to be looking for? Right now I am just thinking about the crossbeams for a elementarry type proa. I was going to try the folding method that rob is using on Solitarry, but I figure that we probably can't use carbon cloth, because it won't bend. I was planning on 17oz fiberglass cloth, with carbon tow running lengthwise. Anyway, I found this on ebay, and it had some specs, so I thought someone could tell me if this is the type/weight of tow that I should be looking for:  ebay carbon tow - Gardner
