Thermally sprayed ceramic released from its mandrel by immersing ceramic part and mandrel in cryogenic liquid. Technique takes advantage of difference in expansion coefficients.
Need for lightweight materials as structural components for future space transportation systems stimulated development of systematic method for manufacturing a polyimide/graphite composite. Laminates manufactured by process are void-free, exhibit excellent thermo-oxidative stability up to 315 degrees C (600 degrees F) and are 40 percent lighter than aluminum. Process is precise, repeatable, and ideally suited for researchers and small-lot producers of composite materials.
