[net.rec.boat] kevlar/carbon hull construction

ec120bgt@sdcc3.UUCP (ANDREW VARE) (04/06/85)

   I am interested in communicating with someone who either has
   experience in building boats with carbon fibre glass or kevlar, 
   or owns a boat built of same and can argue  the
   relative virtues of either. I know of the price-related factors
   involved but my engineering info is zilch and would like further
   knowlege of things like 
                       -life-cycle durability  
                       -documented materials-failure on real boats
		       -any current research on related topics
			
			THANKS!

Any builder or designer of larger racing boats will be familiar
with these materials. In San Diego, for example, is Reichel/Pugh
Design PO Box 6050 San Diego 92106.

I've worked with regular fiberglass and a bit with kevlar (all in
the course of repairing a Pearson Ariel).  Kevlar is very tricky.
It's hard to get the resin to soak into the fibers, and of course,
it's hell to cut.  Thus, there seems to be a much higher risk of
delamination.  Awfully strong, however--indeed, bullet-proof.
