3D-Printed PEEK Heat Shields: NASA Tests Prove They’re Ready for Extreme Re-Entry 🔥🚀
Spacecraft re-entry is basically a 10,000°C inferno —and traditional heat shields (like CF/PEEK) often expand like balloons under pressure, risking mission failure. But researchers just dropped a game-changer. 🔧 Tested in NASA’s brutal arc-heated wind tunnels (think: 12.6 MW/m² heat flux —ouch!), it outperformed older materials by resisting deformation and staying stable. 🌌
