I tested Lexan at Miami University with liquid nitrogen, dropping a steel block onto a 4x4 sheet of 1/8" Lexan after being soaked in the liquid nitrogen, and it didn't even crack.
Needless to say, we are pretty confident in the rigidity of our design.

It looks like 3/8" polycarbonate, so I'd guess that'll probably be plenty strong for your needs.
It
is possible, however, to break polycarbonate in competition; particularly by bending. While it's great at withstanding impacts, if something manages to grab between your timing pulleys and polycarbonate, it will break.
We know. We broke 1/4" polycarbonate last season.
