3 to 5oz fiberglass will do nicely. You can use the 30 minute epoxies, but my experience is that they don't harden as well as a true laminating epoxy.

Steven,

I'll have to go with 6 oz cloth and at least one hour pot life epoxy. I've found simply that the shorter the working life, the less strength the fiberglass will have. The laminating epoxy that Jake is talking about that at least 12 hours (or longer) to completely cure. Just remember that more epoxy does NOT mean a stronger joint... what you are looking for is simply to wet out the cloth, not make puddles in it.

good luck with your project..

Go with lighter cloth and more layers. One layer of 6 oz cloth is the same in weight as 2 layers of 3 oz cloth or 3 layers of 2 oz cloth BUT the more layers of cloth you use the stronger the part will be. You can get them all wet and applied at the same time, just put the first layer in and wet it out then stick the second layer on top and wet it out continue until you have all layers in and wetted out. It wil go transparent when wet and this shows you any dryspots.

the more layers the more crossed fibers hence strength resin alone is brittle the fibers give it strength. I like Matt instead of cloth

sorry but I must dissagree Matt & cloth are TOTALLY different being from that industry. Cloth is like a silk material where the threads are woven togather in a pattern. Matt is fibers bound togather in every which way Like in chop. never seen matt outside of industry, always cloth in LHS.

I was using the term in the broader sense of being fabric. Go be pedantic elsewhere.
