I took two weeks off from the Argie 10 in order to go and work on Ocean
Planet, in Portland, Maine.

Now that I am back, I have a piece of carbon fiber cloth to cover the
bottom of the dinghy with. Funds are real tight and I am afraid that
using epoxy to affix the carbon fiber will use too much of it up, and I
am contemplating using some polyester resin I have lying around from a
project some time ago. It is still good, I fixed another dinghy with it
this spring.

The fiber is just for scuff protection. Any thoughts pro or con?

Thanks,

Jonathan

Con on both from my viewpoint. Polyester and carbon do not mix well, IME.
Also, carbon is very bad in "scuff" mode, which is why it is usually covered
with Kevalr in areas where that may happen.
But... it was obviously free (ish) so what the hey! CAn't lose on that one,
but try to use epoxy as most carbon is not sized for polyester.

Hi there . carbon fibre is to be used for fairings on motorcycles some
expensive autos and other high end machines . It is not fire resistant or
abrasive or structural material. I have used it with epoxy and it does a
nice job in special applications. Do some research before you use it.

You have to bag that stuff to get it on right.

It might be more economical in the long run to purchase glass fibre for the
dingy and save the carbon fibre for a time when it would be needed.

Steve,

I understand it's not ideal for the application, but... the plywood is
only 6mm. I'll use epoxy...am I correct in believing that it's better
than nothing?

Wait..wait...I see some 4.24 oz glass cloth on ebay that I can afford,
would that be appreciably better?

Don't waste your time or your money.

A 50 yard roll of 6" boat tape is about $35 around here.

If you don't want to spend that much, find somebody that will sell a couple
of yards of glass cut from a roll.

Any of the following will work:

DB170, 17 0Z Double Bias
DB240, 24 0Z Double Bias
A 22 0z Triax, +/-45 & a 90.

$10 should cover the glass.

Have fun.

SFWIW, doing this same repair on a friend's 24 ft stink boat right now.

no need to buy a roll. you can buy it by the yard at automobile retail
stores and could try calling hardware stores. you might find an outlet
under "plastics" in the Yellow Pages who sells fibreglass cloth by
the yard.

Save your carbon for something else. Here is 9 oz 4" tape by the yard:
