Re-entry vehicle thermal protection.

Reusable launch and re-entry vehicles see surface temperatures swing from cryogenic soak to over 1000°C aero-heating on every flight, then back within minutes. A thermal protection layer has to hold dimensional and structural integrity through hundreds of these cycles without delamination or microcrack growth. Commercial low-expansion glass-ceramics ship at a fixed CTE chosen for a generic envelope; bond one to a CFRP or metallic primary structure with a different expansion rate and the interface accumulates stress every cycle until it fails. Off-the-shelf TPS tiles also force the vehicle design around the material's limits rather than the mission's. The real problem is matching expansion behaviour across a bonded stack that itself changes with temperature, and proving it survives the cycle count, not a single shock.

Strocera supplies the TPS layer as a ready-to-fire powder blend with CTE tuned to the structure it bonds to, anywhere from negative to near-zero across the 100 to 800 °C characterised range. Instead of designing around a catalogue blank, you specify the expansion curve of your primary structure and operating profile; the glass-ceramic formulation is adjusted so the interface stays near stress-neutral through the full thermal excursion. The system is validated against repeated 800°C to 20°C water quench cycles with structural integrity maintained and the events video-documented, outside the spec envelope of any commercial low-expansion glass-ceramic. Because it ships as powder, you form and sinter the geometry your vehicle needs in your own facility, closing the prototype loop in weeks rather than waiting on a finished-blank supplier's 12-18 month custom queue. The result is a reusable TPS specified to the airframe and qualified on cycle count.
