“…The blunt nose of a re-entry vehicle is protected by absorption of the aerodynamic heat, which generates from the vehicle exterior versus boundary layer frictional forces. The TPS material retains the heat on being subjected to aerodynamic heating until the melting point temperature of the TPS material is reached . Ablative TPS materials protect the aerodynamic surface and structures, and since they operate in a wide spectrum of hyperthermal environments, the heat-shielding solutions depend on specific applications.…”

“…The TPS material retains the heat on being subjected to aerodynamic heating until the melting point temperature of the TPS material is reached. 25 Ablative TPS materials protect the aerodynamic surface and structures, and since they operate in a wide spectrum of hyperthermal environments, the heatshielding solutions depend on specific applications. The heat flux under these conditions is primarily neutralized by mass transfer (sublimation and oxidation); which is broadly classified as ablation.…”

Ablative composites are highly endothermic sacrificial thermal protection materials that are indispensable to the aerospace industry. Polymeric ablatives are the most versatile and the largest class of thermal protection materials due to their capability to be to varied hyperthermal environments. Carbon/carbon composites have outstanding mechanical properties at higher temperatures but they are susceptible to oxidation. The oxidation is addressed by matrix modification, application of a coat of ultrahigh temperature ceramics (UHTC), or also by the use of nanostructure-toughened UHTC coatings as discussed in this article. The article presents a comprehensive review of the science and technology of four distinct groups of ablative composites (carbon/carbon, carbon/phenolic, carbon/elastomeric and carbon/ceramic). The selection of the best material formulations for a given environment is ratified by the testing techniques, which have also been reviewed along with a brief discussion on the composites recycling technologies and their environmental and economic impacts.
