Acrylic Sheets
Hi,
My team was wondering whether we could use Acrylite Acylic sheets on the robot. I found that Lexan and Acrylite were both thermoplastic sheets, but I was just posting here just to be sure. |
Re: Acrylic Sheets
I would never use acrylic on my robots. It's impact resistance is just not up to the abuse. I don't even allow it in the lab so it isn't mistakenly used on the robot.
Stick with polycarbonate (lexan.) |
Re: Acrylic Sheets
Seconded. Lexan can defiantly take much more abuse than the acrylic sheets. Lexan can take a full bore robot collision with minor damage while acrylic can be easily cracked if you even try to drill into it.

Re: Acrylic Sheets
Are you asking about FTC or FRC?

Re: Acrylic Sheets
Stick with Lexan as everyone has suggested. Just a note in forming it. If you "heat soak" it for a while at below thermoform temp, you force out trapped vapor, and eliminate bubbling in the sheet that occurs if it is heated too fast. Experiment and it's appearance will be maintained.:) ::safety::

Re: Acrylic Sheets
I vote for polycarb, over acrylic. No matter where it's used.

Re: Acrylic Sheets
FRC rules do not allow acrylic (Plexiglass (tm)). Stick with polycarbonate (Lexan (tm)) as it is impact resistant.

Also, he isn't in FRC, he is in FTC. Different rules. |

For either program, acrylic should never be used, except for some really obscure exception or something. Always always use polycarbonate. |

I can think of more than a few roles where acrylic would be suitably strong, such as concealed ball hoppers/dividers or decal backing. Just never use it for anything structural or might otherwise take any shock loads. |

Any "real" crab module will have zero acrylic in it, and I'm hoping my team's replacing the temporarily acrylic parts of the prototype rather than waiting for competition to build one that's strength testable... |
