Chris, if you decide to use the carbon, laying multiple layers at 90 degrees to
one another is fine. If you were laying up this way over a wing for example, it
would be stronger than using bidirectional cloth. When fibers are woven in and
out to form bidirectional cloth, the fibers are actually not as strong because
they are not in straight lines. They end up with tiny kinks, up and down as the
weaving process leaves them. Unidirectional fibres are the strongest.

I need to make a canopy frame, what I am intending to do is mount the canopy,
make a frame from foam and fit while the canopy is in place, and glass over
with carbon fibre cloth. Bi directional Carbon cloth is about $60 -$70 per
metre, so I was going to use some unidirectional cloth for about $12 per metre
and alternate the weave at 90 degrees to each other, Any problems or flaws in
using the cloth in this way? any better methods?
