Make your own carbon fiber hood?
�
�
I know its possible to buy fiber glass to mold/design with but can you do the same with carbon fiber? If so is it worth the exspense and where could I get it?
| BillyD | 04-14-2005 10:57 PM |
I HIGHLY doubt its a DIY. They cost money for more than just the raw materials... you need equipment, not to mention lots of trial and error as you get the mold right. I'd leave a CF hood to the pros. But, I suppose it could be a nice project!
| dabigmooish | 04-15-2005 12:33 AM |
why I have no illusion that it will be easy,but I don't think it will impossible either. I've seen people do custom fiberglass. I can't imagine it would be much harder.

Fiberglass has got to be a lot cheaper than carbon fiber though. Any mess up is going to be big $$.
| wil69 | 04-15-2005 01:03 AM |
carbon fiber comes in soft cloth-like rolls. pull off a sheet then u cut it to the shape u want, mold it and bake it. i think thaz the process, loosely.
| nomadtw | 04-15-2005 04:48 AM |
aren't most hoods out there that are CF overlay on fiberglass just normal resin cured not actualy autoclaved...
| SLIGHTLY | 04-15-2005 05:17 AM |
The hardest part of doing CF is getting the weave even and strait.
| andrew12 | 04-15-2005 06:54 AM |
wow... ok you need a lot of special equipment for this. it is not like fiberglass at all, its not like you can just sand and buff out any mistakes. plus carbon of fiber must be baked and cured using a special over that gets to very high temperature... good question but it's not really possible to do it.

I have seen people lay small pieces of carbon fiber without baking them.
| inchoate | 04-15-2005 08:24 AM |
check out aircraft spruce. they have lots of CF supplies.
| azimiut | 04-15-2005 12:02 PM |
you do not need to bake it. it can be done just like fiberglass. however like said above, getting the weave right is really hard. so, if you do it, expect to paint it.
| bunot | 04-15-2005 12:06 PM |
it can be done. it's called overlay. you lay over the CF cloth on the stock hood. i recommend painting the hood black so it's harder to see imperfections when the weave is imperfect. also, get a 2X2 twill or 4X4. the better the weave quality, the lesser chance of screwing it up. i've done a lot fo reading on this as i plan on pursuing the same project.
if you need more info, head on to the fibreglast site. they have a forum where actual CF manufacturers can help you.

You need to have a lot of expensive equiptment and a good facility. A vacum must be ran for like 7 hours for the epoxy. The carbon fiber itself is expensive.

My buddy makes for an aerospace manuacturer that makes specifically carbon fiber parts. Its true that there is no [B]need[/B] for expensive equipment. However, that is also dependent on the proposed use for the material as well as the reasons for going to carbon fiber in the first place.
There are many types of carbon fiber just as fiberglass, one main type is prepreg which can be molded but then must be baked. Depending on your goals you need to determine what type you should get.
If all you want is the look I think you would be better off waiting a couple months as I think it was at SEMA or something where a company debuted a carbon fiber tape that is actual carbon fiber that lays flat with the weave oriented correctly and can be placed and smoothed over objects (eg hood, dash, wheels :huh: whatever). That would probably be the most cost effective way to go.

working with CF is actually quite easy...I just laid down a carbon fiber seat using nothing more than a few cheap/easy garage tools. this seat is going to be used on a FSAE car...you can also vacuum bag using a shop vac, but be sure not to pull too much vacuum
| team_orion | 04-15-2005 01:50 PM |
To do it right it will cost mor ehten buying it.
That is to do it right, you can do it wrong for cheaper but it will be obvious this was done.
Carbon fiber is a different animal all together then fiberglass also remember the heat that the epoxy's you use will be subjected to on the hood of the car I have seen a lot of homade jobs warp/melt cloud up delam all at the attempt of saving very little money.
Best method get pre-preg CF and use a vacum mold in an autoclave or use resins that create there own heat.

Hahaha... the amount of ignorance here and assumption run amuk is hilarious. Working with CF is just like fiberglass, just a lot more expensive. Same epoxies can be used, same mold styles, and it's really not hard to do. Just hard to do well. Getting the weave to look right and making molds correctly to get good pars out is not easy, but not hard. If you put some time into it and don't mind messing up a few parts, anyone can do it.
| skunkfifty | 04-15-2005 01:58 PM |
odd, i just came on to look around for information on how to make a carbon fiber rear diff skid plate. anybody ever done that? should be easy enough (compared to a hood) and who cares about looks
| CBRDSpeedfactory | 04-15-2005 02:00 PM |
working with carbon isnt easy....
especially not to do well, you really need to atleast use vacuum bags to do it nicely, if u dont have an autoclave

Hahaha... wrong!
I have worked in a couple different industries first hand designing and manufacturing with both FG and CF (SnowSki, Automotive, Robotic) and can tell you with out a doubt though they share some main characteristics however they are not the same when working with them.
Unless you consider working with denim and silk the same? (My minor in college was fashion design so we can go there too.)

Curious about how they give it a "dry carbon" look. Anyone have any info?
| team_orion | 04-15-2005 04:26 PM |
One cheap way is to simply hit it with a scotch bright pad but that is if you want to make a glossy finish look matte.
Depending on how it was made also has a lot to do with it.

Well, I see not only do I not need expesive equipment, but its really hard to do, requires expensive equipment and its easy to work with :rolleyes:
I'll stick with the Honda tech article. It seems to have answered my question

That's actually not a bad assesment. Making structural parts (things that see alot of load) are a lot harder to make and require the expensive equipment to ensure the part is uniform and properly cured. Using prepreg (the epoxy is already in it) requires vaccuum and baking the part (autoclave = very very expensive $10,000 per use at my school!), ends up turning out way nicer than hand laying dry carbon. Laying up dry carbon using fiberglass techniques can make nice parts (a little less strong) depending on who's doing it. The most time consuming part is making the mold which is a total PITA! Using a vaccuum on this stuff can help eliminate bubbles and make a nicer part but NOT required. The heat required to cure a part all depends on the epoxy, some need it some don't. Just follow the directions!
IMHO..... If your making something some other company already makes, just buy it. It's usually fiberglass with a pretty top layer of carbon. :rolleyes: Carbon is extremely expensive when you try to buy a little bit. Some of that stuff has shelf life so getting some of it that is expired for cheap is possible and usually still good. But if you want something custom have at it!

The whole "IBcarbonfiberishardtodamage" thing is a joke, dude. Don't go laying up your own underbody armor.

it really would be as bad as you think, all you would need is mold of a hood(the hardest part) then just order the carbon fiber rolls and lay it on and put on the epoxy. ive made small little carbon fiber things before. its alot of fun
