Carbon fiber exhaust sheild???

[brassnuts911]

I see that some eclipses are burned on the bumper from the exhaust gases, and i was wondering if someone like me with quite abit of experence with fabrication, can create a carbon fiber "hole cover" that comes up 6 inces and curves with the exhaust outlet hole like you see on evos. Can i get carbon fiber that flexable and will stand heat? and can i rivet it to the bumper? Ive looked and i just dont know what to call this piece and my searces have beed unsuccecfull. And are there any pictures?
Thanks B-nuts.

386-customs makes them.

I'm not 100% sure if a carbon fiber shield would stand up to the high temps without warping. A sheet metal reinforcement of some sort would give it an added rigidity and would help to reduse warping.

I agree and plus I haven't heard great things about 386 recently. I believe they go under another name now, even another website.

I think it would be neat to get one with an exhaust delete. That way those of us with side exit / open downpipes don't have a gaping hole in the rear fascia.

If I'm not mistaken the "burn" mark is just smoke residue from running rich? I see that crap a lot on hondas and I'm sure they aren't running high exhaust temps

The way to do this is take a mold of that section of your rear bumper. This will give you the proper shape you will need. When the mold is done you lay in the carbon add resin and if you want vacuum bag it down. They make resins that are made for high temps and will hold up no problem to the exhaust at the back of the car. I would rivit the part on when done. It's actually a pretty easy part to make and when you are done you will have a mold so you can make a bunch more for friends or whatever. I would also spray it with a automotive clear to protect the resin from turning yellow.

^Agree, byt you don't need high temp. resin just the right resin. I use WEST SYSTEMS epoxy which is good to somewere in the 400-500 degree range for engine bay stuff and it has held up fine. You can use high temp. clear coat also. It just doesn't like direct contact or flame heat.

I always liked west systems stuff. We used it for a long time. We just switched back from us composites brand for the latest set of world challange car bumpers we are doing. Forgot how nice it was.

what do i make the mold out of?

I know same here. I really want one but not willing to take the risk.

 

[gixrman]

what do i make the mold out of?

Fiberglass and wood.
If I was'nt so busy with the new baby I would make the mold and make these damn things. I have a garage full of supplys and no f-ing time. So much for becoming a freelacer this year.

 

[brassnuts911]

Ok so i make an exact replica out of wood? Then waht>?

Then you put down mold release and lay up carbon fiber onto it. Wait for it to harden, pull it off, and there you have it.

or if you want to make several go here and learn how:

They have great tutorials on making just about anything automotive related in composites.

It's not the carbon fiber that can't take the heat, its the resin.
The carbon fiber is formed under extreme heat/pressure, it can take almost anything you throw at it.
