I'm looking at retrofitting another commercial trailer frame with a floor to make it useful for cargo hauling. I've used 1/4" thick HDPE sheet before and it's been bombproof, as well as completely uncaring about weather and road salt. However, it's
HEAVY. Does anyone have a suggestion for a material that has as good or better stiffness than 1/4" HDPE, still is completely unaffected by the weather, yet weighs less?
Yes, I realize I could spend a million dollars and make a honeycomb-core carbon panel. No, I'm not willing to do that.
