Well, someone did make a bamboo composite cat from the looks of it. Wonder how much it weighs...?
From bamboo surfboards hawaii website...
After over 10 years of bamboo board making, I would estimate that each layer of rotary bamboo veneer is roughly as strong as one layer of 4 ounce unidirectional fiberglass. Two layers of bamboo veneer with grains crossed, epoxy laminated and vacuum bagged uses less resin than a hand laid-up 8 oz. fiberglass. On bamboo NFC surfboard decks I use as many as five layers of bamboo in high stress areas. In the fin box area, up to three layers of bamboo are used.
