Very nice design and amazing progress. My team is considering using fiberglass in our frame this year and I have a few questions. What is the tensile strength and impact strength of the fiberglass, and also where are you getting it? All i can seem to find is fiberglass with an impact strength of 25 ft.-lbs./in. and i would think that would shatter if the bot was hit. Thanks.

Hmmm I think I have seen this bot before. Oooo right I watched some of the building. It's looking really nice guys keep up the good work. Can't wait to see the end result.



P.S Keep pumping out the awesome tune

Creative Pultrusions sells structural fiberglass. It is plenty strong (if used wisely), it has a tensile strength of over 30 ksi (30,000 psi) in the longitudinal direction, and about 8 ksi crosswise. Bearing strength is over 20 ksi.

We used pultruded fiberglass for our frame the past 3 years, it's very tough...it won't get bent like aluminum, and it takes a lot to break it.

This year we're trying out plywood...partly because we ran out of the sizes of fiberglass we needed...partly because we want to try something new. Should be interesting!

Ok great, thank you. And they aren't that far away to boot.
