Re: Working with Lexan

We're a rookie team, though, and since we don't have any experience in how rough things might actually get, or how much the polycarb would cost...
As a rule of thumb about lexan/polycarbonate:
load bearing or going to take hits 1/8" or larger

non load bearing plates for numbers and such 1/8" or smaller.

The uses of lexan in FIRST basically come down to how flexible you can accept during use because even with the forces involved in robot collisions i have seen very little polycarbonate break. So the thicker it is the less flexibility you have and vice versa....Plexiglas is another story all together.
