Every year since 2006 I have found some component of the robot that could benefit from a composite material and lead the team on it's construction. Do we have to use composites - NO. We do it to expose the students to them. As far as doing a whole frame or chassis, this would require expertise and considerable experience. If a team does not have this, don't attempt it. Start off with some smaller lay ups. There is always fiber glass pulltrustions to work with. Done right composites can can be wonderful. Done wrong you have some expensive trash.
