Chainsaw Repair

I've been doing quite a bit of research lately on carbon fiber. There's a U.S. company that makes and sells to the public C.F. plate in many different thickness and grades.
The stronger the lighter grades really jump up in price, but not crazy expensive what I was imagining it would be.
Highest grade is very stiff and light over a steel and aluminum.
With the right grade of C.F. I can  possibly see a competition guide bar can be cut and have a roller nose riveted to it. Only steel in the bar would be the nose.

Anyone have thoughts on this?
