The one-piece CR-9 front wheel weighs 7kg (15.73 pounds), has a rim diameter of 19 inches, and attaches to metal hardware with a patented joint system under dynamic loading conditions. (Source: Carbon Revolution)
The only impossible thing is skiing through a revolving door.
If there's incentive enough, a chemist and the company backing him are going to be very rich.
You've forgotten carbon comes in several forms (cough cough diamond cough cough). It's clear, fiber's been black all this time. Surely there's some room in the middle for a bit of color. Maybe the fibers are carbon nano-tubes, and the interiors can be filled with a colored element.
I wish I had the capital. I see a mint in the making.
Sorry had to edit this. Browser I was using to reply left all the spaces out.
I look forward to it! I love technology, and I imagine there will be a huge safety factor put in. I just keep having visions of things like the time Kimi Raikkonen was on his way to win an F1 race and his rear wing let go. It put up with several G's down force--until it didn't--then it was instantly obliterated. Ductile metals have a forgiveness as they are over loaded they fail and stretch and deform until becoming unusable. Carbon fibre is so strong but past the yield point it seems its almost instant fail. In concrete we use rebar to offset the brittleness. Maybe this carbon fibre will have some stretchy/bendy fibres???
Sven, I think your concerns are real, but so is the crash-worthiness testing of carbon fiber made for high-volume automotive apps. Not all carbon fiber composites are made in the same way. Stay tuned for my upcoming September feature on this topic.
I wonder about true real world impact testing on a carbon fibre wheel.
See the old steel rims could take a curb or nasty detroit pot-hole and you could drive off with a dent in the rib. The tire might leak some air on the way home. A mallet or a torch and you could get it back into shape.
The aluminum wheels are usually pretty good, but occasionally I've seen a pot-hole crack the aluminum and the wheel is toast. I've seen people weld aluminum rims, after damage, but I'd stay away from that.
Carbon fibre is brittle and shatters. I envision hitting a curb or nasty pot-hole and having the entire wheel splinter into shards. Most of us have seen carbon fibre at the race track and what happens during impact.
Looks like a really important development effort. Not only does the wheel help with the lightweighting strategies of automotive OEMs, I'd say it's still pretty good looking. Given that style is such an important element of car selection, I'd say any kind of modifications to materials or appearance in the name of lightweighting vehicles still has to have an appeal to consumers and I think this example satisfies both.
The grab bag of plastic and rubber materials featured in this new product slideshow are aimed at lighting applications or automotive uses. The rest are for a wide variety of industries, including aerospace, oil & gas, RF and radar, automotive, building materials, and more.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
