Abstract: A thermal protection system capable of withstanding impact loads without a detrimental effect to its main function, i.e. a protection of the vehicle from high temperature during re-entry or flight in the atmosphere. The system consists of the outer ceramic matrix composite shield, a ceramic tile sandwiched between the shield and the skin of the vehicle and fasteners joining the system and the protected structure. The ceramic matrix composite fasteners are capable of working in the same high-temperature environment as the rest of thermal protection system. They are also strong and stiff due to the presence of ceramic fibers. Cracks in the outer shield produced by impact cannot propagate into the ceramic tile since the shield and tile materials are discontinuous along the interface. The tile cannot disintegrate from the vehicle since it is pressed to its skin by the outer shield. The system can easily be disassembled for inspection and/or repair.
