Carbon pre-preg

So I have this roll of carbon pre-preg. Is there any way to use this stuff in some skis?
It is some carbon from Hexell corp. It has not been kept frozen, but it looks normal in every way.
So I need an opinion from somebody who knows about this stuff, can it be made to bond in a layup? Its just woven carbon and epoxy.
I have re-epoxied a ski that completely seperated and it held up fine. I just sanded both surfaces and re-pressed it.
Can I just sand it? I hate to think that all this carbon is useless.

is it still wet?
If so, yes if not how would you unroll it?
How old is it?
Most carbon prepregs call for a 300F cure or more to get 100% results but it will cure mostly at 180F if left for long enough.
What weight and weave?
Hexcel makes some super stuff.

keep it in the freezer until you use it...

Sadly I don't know how old this stuff is, it looks like a fairly heavy weave but it doesn't say what it is.
It is fully cured so keeping it in the freezer wouldn't do any good.
The roll is 40' long by 40" wide so I really hope I can save it.

If its cured in a roll, how would you unroll it?
Shit is toast.
See if a carbon recycler will pay shipping to send it to them or something.
If it was in sheets maybe but you would have to heat it past the glass trans temp to get it to flatten and bond in a ski IMO which is prolly pretty high temp for a prepreg.
