Episode notes
Picture-Frame Carbon Design Peels Under Vibe
- Wesley tried an ultralight carbon-fiber picture-frame approach and pushed it beyond structural limits in vibration tests. It failed by peeling the carbon face sheet off the frame, forcing heavier fixes and a rethink toward sandwich panels.
Carbon Fiber Adds Hidden Electrical Risk
- Carbon fiber introduces conductive microscopic fibers that raise arcing risk near EP systems, forcing insulating layers like Kapton and adding mass. That partially offsets the weight gains from carbon and affects material choices.
Choose Procurement-Ready Panel Tech
- Evaluate rollouts, sandwich, and PCB-backed panels against procurement lead time, efficiency, and production volume needs. Prioritize solutions you can source reliably at scale rather than bleeding-edge tech with long lead times.
