Hi!

Hey Kylle,

that looks like standard 200g 2/2 twill carbon to me, to repair it I woudl go to chop out the rough cracked areas with a dremel and then sand the area for about an inch arond the hole and cut some peices of profinish cloth (i'd use profinish so it doesn't fray on the cut lines) and carfully laminate over the area, i'd guess you'd be best using the high temperature epoxy resin, about 2 or 3 layers would be enough i'm sure, then when it's cured sand it down smooth and apply another thin coat of resin to seal it and give it a gloss. this sort of repair won't be invisable (I don't think you can make an invisable repair on carbon) but it should be strong and look neat.

It's not a aesthetically repair that I looking for.  the repair patch doesn't stay visible....

well what i do when i repair an exaust is i lower the area where i want to add the carbon  so i sand the surface and cut it with a sharp knife usually i prefer square cut   , 1st i use a polyurathane foam from the stores and to tell you the truth i buy the cheapest ( all r same) i put some in the hole that was cut and  leave it for the second day , what will happen is that the foam will make u a surface and then flatten it by cutting the excess and sanding it a little lower  ,(at the same thickness of the carbon layer plus the resin).

i take a larger part than it needs and i clear coat it a little or i use a wide scotch tape on a layer so i can get a perfect cut and  i cut it with the scisor to perfectly match the area im going to put it in(weave will line up on all 4 sides) , then i use the overlay method , adding a black resin to the area covering the outside area with paper tape so it wont be touched and then stick the part i cut when its tacky , and i put 2 to 3 layers of resin and sand it to 2000 and polish it which i recommend to your part or clear coat all the part .

hope this is useful to u or at least ,may some of it give you a better idea to be done .

tanks;

but I tink I will disassembly the whole thing and start working from the inside. After renforcing the inside, i will do was U said in the outside but without the foam,... theres a big crack that isn't visible on the picture....
