Does bias carbon tape exist?

I am somewhat flexible on the exact width (1" to 3"), but this would be a true tape (two selvage edges), not just slit, with the fibers running 45/-45. I will consider knits, weaves, or braids (preferred). I am considering doing a double stitch down a length of braided tubing then cutting it open to make my own! Any simpler solutions? Do A&P secretly make Bimax tapes?

Like so? http://www.sollercomposites.com/composites/carbon%20fiber%20uni-fabric.html#carbonbiaxialtape

When I worked in the USA I got some from www.braider.com

Soller, is right near us too! I assumed that was a tube because it gives changing width dimensions…

Did it have a fixed width, or was it adjustable like braided tubing?
