Ultra-high temperature ceramics are desirable for applications in the hypersonic vehicle,
rockets, re-entry spacecraft and defence sectors, but few materials can currently satisfy the …

Abstract Ultra-High-Temperature Ceramic (UHTC) materials, because of their high
temperature resistance, are suitable as thermal protection systems for re-entry vehicles or …

The reentry conditions endured by a vehicle entering the atmosphere from an Earth orbit or
from an interplanetary trajectory are the most critical phases for materials used as Thermal …

Some aspects of heat transfer upon the interaction between components with a sharp
leading edge and high-enthalpy high-speed flow of dissociated air have been considered; …

Abstract Zr-Ta-B-SiC multiphase coating was prepared on carbon/carbon composites by
pack cementation and slurry method. The (Zr, Ta) B 2 solid solution was found to be the key …

The ablation behavior is crucial to the application of carbon fiber reinforced silicon carbide
(C/SiC) composites in thermal protection systems of spacecraft to enter the atmosphere or to …

Various thermal protection materials exhibit obviously different and complicated thermal
response, oxidation and ablation behavior, which are very important for the appropriate …

In the present work, five kinds of UHTCs coatings (ZrC, ZrC-SiC, ZrB 2, ZrB 2-SiC, ZrB 2-ZrC-
SiC) were fabricated. The difference of ablation behavior between ZrB 2-and ZrC-based …

In order to satisfy the requirements for the thermal protection system to serve at ultrahigh
temperatures, carbon fiber reinforced silicon carbide-hafnium carbide (C/SiC-HfC) …

In this paper the microstructure and mechanical properties of two different C f/ZrB 2-SiC
composites reinforced with continuous PyC coated PAN-derived fibres or uncoated pitch …
