Résumé : |
A porous state-change material has been developed as part of a reconfigurable tooling system. The primary form of this material consists of hollow glass microspheres suspended in a water based blinder. The material is hardened by applying vacuum and elevated temperatures to the liquid slurry, leaving a thin binder layer between microspheres that holds them together. Mechanical and thermal characterization data for this material has been previously reported for relatively low temperature applications. There is interest in using this tooling system for the fabrication of the polymer composite structures that require processing temperatures in the range of 400°C (750°F). The material must withstand the thermal-mechanical loading experienced during the fabrication process, including the thermal cycling. Compression and flexural mechanical properties and coefficient of thermal expansion are determined at temperatures up to 400°C (750°F). Room temperature properties of the material are also determined after thermal cycling up to the same temperature. |
