It's more than just that. Simple vibrations will crack the acrylic where the bolts go through to mount it to your backing. Acrylic is not acceptable for a FIRST robot under any circumstances. If I won't use it in my computer for waterblock tops (where there is negligible vibrations and no movement), you definitely shouldn't ever use it on a FIRST robot.
Theres a few companies (Thermaltake) that used to make waterblocks with acrylic tops and meager 10°C changes to the acrylic along with the pressure the barbs put onto the threadings to maintain a watertight seal caused many of these blocks to crack and leak water over the users video cards and motherboards.
