Carbon Fiber: Compensation or Retardation?

[speedminded]

dry carbon? lolol theres no such thing. carbon is carbon. the expensive hood you saw is actually made of CF, the cheap one is fiberglass frame with 1-2 CF top layers.

You've obviously never worked with or know anything about carbon fiber if you think there is no such thing as dry...

Quote from http://www.agemate.com.tw/carbon-in.htm

"Dry carbon fiber is made in a pre-preg and dry process which consists of vacuum forming sheet of carbon fiber into a mold at temperatures around 350¢K, this process allows carbon fiber to form into a strong and lightweight composite.

On the other hand, wet carbon fiber is formed by using hand laid carbon fiber sheets into a mold then mixed with resin (30% carbon fiber, 70%resin). This process may allow air pockets form inside, then makes the wet carbon fiber structure weak and also is susceptible to changes in temperature."

I was using my car as an example. My hood is like twice the size of an ordinary hood... plus the fenders are incorporated. you cant even lay it with a 60" sheet. (the biggest available IF you can find one) Supply costs have more then tripled for CF in the past 5 years, most of it going to the military naval and aerospace industries. Most mass produced molds will be a bit cheaper, seibon wanted over $5g a piece to run 10 hoods for the sky... its just rediculous when you can glass a hood for so much less.

Dry carbon is what has always been know as prepreg. When you receive prepreg it is cloth preimpregnated with frozen resin. It is like a roll of cardboard somewhat in consistency and workability. So its "dry" until you put it in your vacuum bag, pressurize it and heat it up and that frozen resin now flows in you mold, cures and you have a badass part. Wet layup is anything other than prepreg. That includes chopper gun, hand-layup, vaccumbagged wet layup, its all not prepreg.

jeez lol i already said i get it. i just know it as wet layup/prepreg

^^YOU need to stop stalking before you sound more like an idiot than you do now.

There are two different types of CF... impregnated and dry. Impregnated cf is what you generally see used in DOT hoods/exterior pieces. It is "impregnated" with fiberglass resin so that when it gets laid with a fiberglass frame and vaccuum formed, it will bind better to the fiberglass frame. It's also a bit easier to work and will give you a much glossier shine as the end result. 90% of the cf on cars you see is impregnated. Glossy, pretty, nice deep weave texture, but the problem is it's also heavier, since it has so much fiberglass in it. Usually an impregnated cf hood will weigh about as much as a fiberglass hood, sometimes more. Either way, impregnated cf hood you're looking at weighing about 27-35 lbs, where a metal hood will weigh 35-40+ depending on the car.

DRY carbon fiber is when you literally take a sheet of carbon fiber and use immense pressure and heat to form it. It's not as pretty, not as glossy, but is MUCH lighter. Like we're talking 9lb hoods. However, it is almost impossible to get DOT approval for dry CF, they're more expensive, and they don't have that trademark "bling" effect that impregnated does. However, you see dry cf used a lot in interior applications, since it forms around complex curves easier. It's then painted with high gloss clearcoat/laquer to make it look shiny.

i can talk all i want. i work with carbon on a regular basis and elan composites. i know what im taking about. there was just different terminology used that i hadnt heard before.

for one thing, no real carbon fiber hood has fiberglass in it. it might have a glass frame, but in the carbon itself? no. ALL carbon that you will ever see has resin in it. how do you think it stays in shape and is smooth?

I am actually quite anti carbon..
i find it useless to dish out hundreds to get a "look"
i may be indeed partial to unicolor paint schemes. but if you'd like a contrast in color why not paint parts a different color?
in many if not MOST cases people do the carbon thing for a look and its a complete waste of money.

[GSRTURBOTEG]

I have a car the the whole thing is carbon fiber and no I don't race it or even really drive it, but that is what I wanted and I can afford it so why not? Does a millionaire really have to have three or four homes, plus a yatch, an airplane, and 50 cars? No but that is what they wanted just like a carbon fiber integra is what I wanted...not really dogging your opinion but as I stated before opinions are like assholes evrybody has got one that does not mean we all want to see it.

We don't have a yacht or 50 cars. Not all millionaires live like rappers or athletes. Later, QD.

well said!! Everyone mods their cars for what they want it to look like. Whether you change your wheels, get anything CF, get your car painted, get a body kit, etc., its your decision. Carbon FTW!!!

[GSRTURBOTEG]

I did not paint mine either she is raw carbon and clear that is what I want

[Frög]

ya your right, its it must be "retardation"

here the company that now makes the most profit:





pics of the audi S8 please.. cabron fiber looks good.. End of it..

i dont like carbon fiber hood etc.. but come on..

[LiL PaKi]

i like the way it looks.. cf hood, cf lip, cf spoon mirrors.. and cf eyelids FTW

That's completely ugly. I love how the "CF" eyelids aren't even in unison with the hood. Later, QD.

i guess... i'm just not baller enough because i dont have carbon pieces

Carbon proves that your car is better and has more status when you spend all sorts of crazy cash to mod your vehicle

cause my name conatins CARBON also.

This same argument could be made for tucking wheels and extreme negative camber. People do carbon fiber for looks on a street car, not performance benefit. They may fool themselves into thinking that it has some great benefit, but it was still initially done because they like the way it looks.

All this thread proves is that some people like the way it looks and some don't.

[speedminded]

As for daily driven cars, since when has a lighter vehicle not been a benefit???!!! Ever driven a car that felt a little sluggish after filling the tank up with fuel or added a passenger or two? The performance aspect isn't the main benefit as much as gas mileage...

The problem is the current cost of carbon fiber and the additional labor to create it is [probably] not less than the gas saving acquired...in the long run i'm sure it is though. Ford build a carbon fiber Crown Victoria/LTD back in the 80's that saved nearly a ton of weight but it cost $250k to manufacturer, lolol.

painted CF if you have the money is okay, but showing it off is just stupid. I do think carbon fiber has a nice look as interior trim in small doses though.

On a side note, there is a guy in GA named Mike who had a 450 hp FD that was titled the fastest FD in the South East (184 mp/h).........until he wrapped it around a tree. Now he is in the works for a complete carbon fiber car down to the unibody. He is getting a wide body complete FD made with all carbon body panels. The final car should weight close to 1,400 pounds. That, I would never paint. He is going to fit 365 mm tires in the rear and 285mm tires in the front with a single turbo 13B, racing grade everything (exhaust, suspension, tranny, clutch, etc.) Needless to say, that'll be a beast, he hopes to take the title of the fasted FD in the world.

[speedminded]

Carbon fiber interior pieces are a joke but this ENTIRE dash weighs 2lbs!! I want it for my car but it's $999!

sounds like the car that won in its class at solo2 nationals a year or 2 ago...

This thread = recockulous. You don't want cf on your car, good.. don't put it on. Want cf on your car, good.. put it on. Does it really matter? I mean seriously.

People get their damn panties in a twist so easily.

^ says the person with his pink lacy panties in the biggest twist knot evar. You're hardly in a position to tell me what to do, thanks.

[green91]

The main purpose was to have a lighter weight material that is very strong. If you are able to use CF to shave a few pounds off of body panels, these weight savings alongside other weight reductions do provide a benefit even on street cars. its that simple.

[01CDMLUDER]

i bought a cf hood b/c someone fcuked up my stock hood and i got a cf one for cheaper. i also think it looks good.
