For several years now we have been using 4mm or 1/4" Baltic birch plywood laminated with a layer off 5.7 oz plain weave carbon on both sides. The panel is a structural member of our frame. S2 glass or Kevlar cloth could be used if the conductivity of carbon bothers one. It has not been a problem for us. Last year a sponsor laser cut the panel including mounting holes. We do not laminate the practice bot panel and it does not have the durability or stiffness of the carbon panel. Each year it ensures that the team receives some experience in composite construction.
