Searched: how to repair Carbon Fiber Crack

[95gsrturbo]

I did a search here, honda-tech, youtube, and google, got nothing

I hit a bad bump and broke my CF front lip (not really broken but several cracks and scuffs

can anyone shoot me a tutorial on how to reapair these things- or is the lip shot an have to buy a new one?

i assumed i could use fiberglass from the inside to mend the cracks, then wet sand and clear the outer part to seal the outside (visible side)

im sure if you look close you could still see the cracks but at the front lower lip who would really see it?

Most carbon fiber finished parts (automotive applications, etc.) have a resin clear coat over the cured part. There a numerous clear coats used in various industries. Repairing a cracked or delaminated part is difficult enough. Getting the right clear coat and being able to apply a smooth layer that will match the part is best left to an expert.

My advice is to contact the manufacturer of the part and ask about having it repaired. If they don't perform part repairs, they may be able to recommend someone they use. Repairing CF parts is done all the time. Hope this helps.

It will only be a cosmetic fix that will crack again with any light impact. once the fibers are interrupted the part is garbage. i'd go back to oem, for obvious reasons. just .02

Many companies use a ton of gelcoat to cover their products. This can hide a lot of imperfections but it also make the surface very brittle. Generally surface scuffs can be sanded/buffed/top coated but cracks are difficult to repair. I have seen some good repair jobs but most of them come back. Many of the cosmetic parts are not made with enough reinforcement to support the part itself. Irt is to expensive to make them tat way. So they use the gelcoat to add strength. Once the gelcoat fails, even if repaired, the part will want to fail at the same place again.

I say just bond it and paint it, obviously doing so you won't see the CF but at least its a easy fix and you can save money from buying a new lip.

Give it a try, you have nothing to lose at this point. Fiberglass wont be as strong and will probably crack again, but it all depends on how much time you have.

Thats why I have an OEM lip, too many dips and steep driveways to contend with.
