摘要

Atmospheric reentry vehicles require materials for reusable heat-resistant structures and thermal protection systems. HOPE-X, the Japanese experimental spaceplane, also requires such materials. A nose cap and wing leading edge will be manufactured by C/C composites. The main structure consisting of Al alloy or carbon fiber/polyimide raisin composites (C/Pi) will be covered with ceramic tiles and flexible insulation as thermal protection systems. Those high temperature materials were installed on the Hypersonic Flight Experiment vehicle which was a precursor to the Japanese spaceplane and proved to be functional.rnIn the other hand, ceramic matrix composites (CMCs) has been expected recently to play an important role in the materials used in severe environment such as high temperature and oxidizing atmosphere. So, we have developed fabrication process and investigated mechanical properties of CMCs. It may be confirmed in this development that CMCs trial parts can be fabricated successfully and have reasonable mechanical properties as a result of structural tests on them.rnIn this paper, high temperature materials in Japanese experimental spaceplane and CMCs being developed now for future applications were mentioned generally.
