Sounds solid. Map the loads first, then do a quick stress‑to‑density check on carbon‑fibers, maybe some glass‑reinforced polyimide, and compare with the latest aluminum alloys. Cut out anything that gives you a margin less than 2‑3%. Keep the layers thin and stagger the fibers so the composite breathes under low pressure. The key is to get the high‑strength fibers at the right angles where the stress peaks. Once you’ve nailed that, the weight will follow. Need help crunching those numbers?
