Improvement over Carbon Fiber?
There's a new material for frames set to come out, but I'm sure it won't be available at your LBS anytime soon; nonetheless, it will be interesting to see if this becomes the new THING in frames.

Innegra Technologies makes a hybrid composite called Innegra that combines carbon fiber with a high molecular-weight polypropylene plastic. Both fibers are lightweight. The carbon fiber provides stiffness while the Innegra fiber is resistant to impact damage. Moreover, if the carbon fractures, the Innegra can help hold the structure together so that a frame or component doesn’t suffer a catastrophic failure.

Wonder how asplosive it is.

Oh Lord, he said carbon fiber is fragile. Here we go.

For those who might actually have an interest in materials...

university materials science engineering departments is a good place to start..
Aerospace, and military applications come first, developed with tax payer money , privatized,
then some trickle-down to consumer goods..

that's called a new resin
The first composite bicycle was built in 1894 (using natural composite)

Looks promising to me in terms of impact performance. I don't think it helps with improving resistance to clamping/crushing forces, though. Still, I like the idea.

Yep, that's been in the local news a little. Nice to see some investment.

You can accomplish the same thing with a layer of Kevlar. My avatar bike has a layer of Kevlar on the inside. It might crack but it won't asplode. This new stuff might be lighter, though.

Until they come up with a material that heals itself whenever it gets damaged, I'm stickin' with steel.

Looks to me like a cheaper way to produce the same old carbon fiber.
30 years ago most consumers could only afford a fishing pole of the stuff. Now we can buy a bike. Next up, a car. This looks more evolutionary than revolutionary to me.

I read that crabon fiber is the best all around material. All things considered.

Given that they haven't been around that long, we shouldn't be at all surprised to see CF composites continue to evolve. This material is part of that, but isn't the only thing out there, nor will it be the last.
One of the more immediate changes involves the resins, some of which have more tolerance to flexing.
Love it or hate it CF is new and evolving very quickly.
Of course, after they take your money, they can come back two years later and tell you about issues and how new versions address them better.
BTW - steel is evolving also, so I'm sure we'll still be debating steel vs CF for decades to come.

Artisinal hand made steel frames are better than a mass produced carbon frame spit out of a mold.
Get in the queue for some of the in demand builders with a multi year waiting list.
Richard Sachs , its about 10 years.

All carbon fiber frames are made by hand. Look it up. There are currently no robots that can layer carbon fiber. The "molds" are used in the final stage of processing to hold the integrity of frame when the final epoxy coat is applied.

yea the layup is done with hands , and seeking lowest cost those hands are not in Aspen Colorado.
Post carbon era is when the Nukes have been dropped and all consumerism is up in smoke and buried in the Rubble.
You building Yachts in Florida?

This "improvement" will just become known as a higher grade of carbon fiber.

And what the hell does post carbon area, nukes and yachts have to do with this discussion?
Here's a video that might interest you and other readers. Draw your own conclusions. Modern bikes are carbon fiber composites.
