Which is Better metal or composite materials for the chassis

[Simon Strauss]

I have never personaly used a composite material in any robot chassis but i do know that there are a handfull of teams who have been very sucessful using fiberglass frames. However, since you are a rookie team i suggest that you stick to the standard of aluminum, its light enough to not have to worry too much about the weight limit and due to its simplicity and versitility in fabrication using it will make your lives a whole lot easier than if you were working with another material.
