Can we use Fiber Glass?

[waialua359]

depending on the thickness, you can vacuum form it, and heating allows some pliability if you know what you’re doing.

Cool I didn’t know that. Thanks for the comment

What exactly is lexan?

Polycarbonate (a type of plastic)

Team 104 used fiberglass pultrusions for the arm in 2004 and 2005. Pultrusions are readily available and can be cut and drilled like wood. A piece of 1/4" birch plywood with a layer of glass laminated on both sides makes a very ridged and strong panel. Mixing some epoxy and some chopped glass fibers allows the casting of couplers and other parts. I would strongly suggest that if you use fiberglass cloth and epoxy you spend a little more money and use S-2 cloth. About 30% more strength for the same weight. The pultrusions are easy. Laying up composites takes allot more skill. If you don’t have someone experienced with composites I would recommend not going with it this year. Do your research and practise in the off season next year.

Is epoxy legal???

Personally, I prefer Tuffak over Lexan. Pretty much the same thing, but I have had better experiences with Tuffak…(probably just a luck thing)

PS Hereis some random info about different Polycarbonate types.

We used an epoxy clay in our front wheels to reduce traction and let our 4WD turn. The inspectors at both VCU and Nats had no problems with it. Although the guy at nats had serious issues with our wiring and a piece of tape that wasn’t holding anything on.
