Abstract

To protect space structures from debris impact, the new types of shield using a self-sealing materials are suggested. A hole by debris impact on shield will be fixed with the self-sealing materials by melting, sealing and solidification. Time to seal impact hole was experimentally simulated. If time to seal impact hole was assumed to be about 5 s, viscosity of self-sealing materials should be about 0.5 Pa s. In addition, glasses with supercooled liquids at elevated temperatures were also suggested as candidate materials for sealing, because low values of viscosity were obtained below melting points. From these results, boride ceramics, high temperature polymer materials including a liquid-crystal and light metallic glasses were suggested as the candidate materials for the self-sealing system.
