I don't know about graphite over Dynel.

I did a little looking around the web for you as penance, and because I like helping and was interested in the answer also (but doing it for penance is a more interesting storyline). Anyways, from what I have been able to glean from my research there is no problem using epoxy/graphite with dynel. Dynel does absorb more epoxy than regular glass so keep that in mind. I"ve seen people using 50-50 epoxy to graphite by volume mix or as low as 90-10 epoxy to graphite. A few have even added cabosil in a 50-35-15 (epoxy - graphite - cabosil) by volume.

Here's a couple of the links I found that I thought applied to your question best.

Here's a thread that Bill started that gives some good info on using Dynel.

Of the two alternative fabrics I personally like Xynole. While you will need to use multiple coats of resin to fill the surface after your original wet out, its pretty darn tough as it relates to abrasion resistance. Its next to impossible to sand. So pick your wet out times so that you can continue on with your wet out in the green stage. We have done tests on the products with a solid conclusion of weight versus strength. You can then graphite the surface if you wish when your fabric is filled.

Xynole is a light weight open weave cloth made out of polyester instead of glass fibers. It is very drapable and easy to wet out and as well does not have the fiberglass itch. It is often called the poor man's kevlar because it has very good impact and abrasion resistance. It has good stretch before failure and it makes a good covering over wood hulls and decks as it will stretch and bend with wood's tendency to swell or bend. Remember, do not use for stitch and glue or to hold things together because of its stretch. Use fiberglass instead for strength applications. Lastly if you do not quite fill in the weave it will make a good non skid surface. Call and we will be happy to explain more.

Thanks, xynole is one I was also trying to remember.

Thanks for those Articles Joe they were helpful in getting my memory jogged again. I plan to buy my Epoxy products from Larry down there at Raka Marine Epoxy.

Oyster thanks for remembering Xynole to us.

I have a confession. Last night I've decided to build another boat altogether and from another designer. My basement is all I got right now and so 14' is about all that I can build there. i plan to build it unglued and get it all cut out and accounted for and when spring is here I'll drag the pieces up and screw/glue it together and paint it. I choose this design because it is a glue and screw with no glass work. I've done lots of glass work before and want as little a part of it as possible for this bang around boat. I'll likely cover the bottom with Carbon sheathing and the rest will be sealed with epoxy, sanded and painted or varnished as appropriate.

I can hardly wait to start.
