Mold a frame stronger than carbon fiber?

Stronger to penetration with equal weight and cheaper, but not stiff enough to make a bike frame.

it claimed that a blend of 19% carbon fiber - 71% tegris had the same stiffness as carbon fiber. unless i read something wrong

 

[MadRhino]

Here it says that the more of it mixed with CF, the less flex resistance. If a mix with 43% CF and 57% Tegris makes for 50% loss of flex stenght, and a mix of 21% CF to 79% Tegris makes a loss of 82%, I don't see how any % of this mix could avoid weakening CF stiffness.

You also need heat and pressure to work with the stuff. Not something you can DIY easily. I'll stick with CF, too bad it's not cheap, or I would be building a frame.

im just wondering why it says "equal stiffness" comparison then

I think they mean head to head comparison. "Equal" may not be the best way to describe it.

This from gizmag

Snip...
One example is a carbon fiber/Tegris/carbon fiber sandwich that has equal stiffness to a carbon fiber-only structure, yet is 18 percent lighter, more damage tolerant and requires twice the energy to break. Another is an aluminum/Tegris/aluminum sandwich construction, which takes three times the energy to break...snip

Sounds like it would be great for bike frames.
