Carbon Fiber
 

I'm building a duck hunting layout boat, and it will probably face alot of
dragging across dirt/gravel. I'm thinking of doing the bottom in carbon
fiber.

anyone have a cheap source for carbon fiber?

anyone have a better idea?

Thanks,

Marc

Marc,

Please do some serious research and consider your
alternatives. Corbon fiber is very light, very strong and
not very abrasion resistant. Kevlar is more abrasion
resistant (as I Recall).

Think you will find carbon is on allocation and it ain't cheap.

Try double bias glass and epoxy.

Kevlar for the hull, carbon fiber for the mast, on a sailboat.

For abrasion resistance carbon is definitely the right material. Neither
is Kevlar. Kevlar fuzzes up and carbon fiber is not flexible enough. Best
to use is a tight weave e-glass cloth and fill the weave with epoxy with a
large addition of powdered graphite. That is a pretty standard bottom for
McKenzie style drift boats.

Yeah, use Kevlar instead of carbon.

Thanks guys,

I've decided against the carbon fiber and to go, instead, with the
glass/epoxy/graphite option instead

Did you look at plywood with a glass-epoxy skin... I'm willing to bet
that in comparable panel strengths as compared to an all fiberglass
hull, this will be lighter and cheaper... LOWES has exterior Luan ply,
5.1mm, for roughly ten bucks a sheet... I just finished building a 7.5
foot dink this way and you can pick it up with one hand...

Quite a while back someone from Oz described how they finished the keels and
skegs of their kayaks with epoxy laden with Silicon Carbide, the stuff one
grinds telescope mirrors with. I quote "The ramp doesn't mark our boats.
Our boats mark the ramp."

A thick graphite/epoxy mix, spread liberally on the bottom, is really good.
Put it on as a finish coat, NOT to wet/fill the glass.

Even better, the dories stored on cobble beaches of Grand Manaan Island are
sheathed with UHMW plastic panels. They just slide them down over the
rocks to launch, winch out. The problem is that this stuff doesn't adhere
to anything, and must be mechanically fastened.

What glass are you describing?

You mean, "dense"?
