I wondered how long it would take; whether it is the future or not . . . who knows.

how strong is that ?
and what about dents can it be molded back into shape
It won't dent. It will just break. Carbon fiber has a relativly weak shear strength.
I wonder what the weight difference is ?
Carbon fiber has been used in bicycle rims for awhile. It is a great material but not really suited for this application. I think it's a pipe dream at best.
You may see it in F1 or IRL racing, but I would expect that to be the end of it.
proburlay end up being some hybrid conpound like carbon fiber/titanium/aliminium and other stuff prob cost moocho's denero's
Carbon fibre is basically a plastic. The main considerations would be rigidity (resistance to flexing) and impervious to leaks. It is almost inevitable wheels will eventually be made of this.

Being a senior engineering student, I was wondering if DSMowner or anyone else could explain why shear strength is an issue in a wheel ?? The only possible shear strain situation I can think of is during sliding of the car and even then most of the strain will act on the tyres and not the wheels.
DSMowner, r u an engineer of some sort ??
Sorry. Just let me know which ones Im allowed to post on.Originally posted by guyt_x

I like you you can post where ever you want
Yes, I am an engineer. Any time a car is turning, there will be shear stress on the wheel. The axle will be wanting to push the wheel the opposite direction than the tire, which is why tires fold under when turning fast. Also, anything such as gravel and pebbles hitting the wheel would have a better chance of puncturing it than aluminum or steel. Although, I wasn't saying carbon fiber was too weak to use for wheels, someone asked it would dent and be molded back into shape, and I was answering that question.Originally posted by Misho

Ridgidity wouldn't be an issue with carbon fiber. It's much more ridgid than aluminum or steel. Saying something's "basically a plastic" is a very broad statment, there's many different types of plastic, some stronger and more heat resistant than steel, some like the kind your milk jug is made of.Originally posted by crisis

Hey Dweeb your family's lookin' fer yu...
Is your past catchin' up with you? .......
A pox - a pox I say -
a pox on all those that cling to the use of the oil-burning horseless carriage and pollute the King's highways and byways.
Try to make sense.Originally posted by ozexige
