Carbon Fiber

Below point notes highlight key differences between Aluminum and Carbon Fiber qualitatively, according to this article.

Extra Notes About CF Composites

This is a cool video that shows the difference between steel’s ductile and CF composite’s brittle failure modes. Notice how under torsion, CF breaks pretty cleanly at 45 degrees while steel twists (doesn’t snap).
