It's actually Coroplast http://www.coroplast.com sheet material. The "plastic cardboard" that is used to make yard signs and that sort of thing. Lightweight, stiff, fairly strong, easy to work with. You can get it (or something similar) from most industrial plastic suppliers, or smaller pieces from your local sign shop. There is a ready supply of it at the school because they make vinyl signs in the same room as the robot. We've used it for all sorts of things over the years: guards, hoppers, sponsor/number boards, and even used to use it to mount all the electronics. It's not stiff enough to mount a cRIO though. It comes in a bunch of colors, too.
