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.
Using a 3D printer, CNC router, and existing powertrain components, a team of engineers is building an electric car from scratch on the floor of the International Manufacturing Technology Show in Chicago this week.
In November, a European space probe will try to land on the surface of a comet moving at about 84,000 mph and rotating with a period of 12.7 hours. Many factors make positioning the probe for the landing an engineering challenge.
NinjaFlex flexible 3D printing filament made from thermoplastic elastomers is available in a growing assortment of colors, most recently gold and silver. It's flexible and harder than you'd expect: around 85A (Shore A).
