“…Phenolic impregnated carbon ablators (PICAs) are a subclass of polymeric ablatives, which were effectively used in a stardust probe as primary TPS material . As compared to conventional TPS ablators (SLA-561, Avcoat 5026, and FRPAs), both densified, and as well, standard PICAs offer greater weight saving.…”

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.

“…[15][16][17] For example, phenolic impregnated carbon ablator (PICA) is a typical lightweight ablative material developed by NASA Ames Research in 1990s. PICA, with low density (0.22 g/cm 3 ), low thermal conductivity and excellent ablation resistance properties, was used as the heat shield of "Stardust" to withstand the maximum temperature of about 1600 C. [18] However, the lightweight composite would be ablated significantly when subjected to long time, oxidative environment. [19,20] In order to improve the ablation resistance of phenolic aerogel, the modification of phenolic matrix has been concerned.…”

This article reports a novel lightweight integrated multifunctional composite (LIMC) with good thermal ablative and insulating properties for high temperature extreme environment. LIMC, which is an integrated woven carbon fiber preform reinforced phenolic aerogel composites, was prepared using vacuum impregnation and ambient pressure drying. The as-prepared LIMC consisted of a dense surface layer exposed to environment, and a lightweight insulation zone to manage the heat load. The influences of weaving parameter and resin structure of LIMC on thermal protection and insulting performance were investigated. The results demonstrated that LIMC exhibited excellent ablation and insulation properties, and the weaving parameter and resin structure can affect integrated thermal protection and insulating performance. The 3D orthogonal recession layer with dense aerogels can improve the ablation resistance, while the 2.5D layer-layer angle-interlock with light aerogels can increase the insulation behavior of LIMC. The novel LIMC presents wide application prospects in the field of thermal protection and heat insulation.

“…Along with the rapid development of deep space technology to the planetary exploration direction, the study of high temperature ablative thermal protection materials meet new challenge. The ordinary surface heat insulation materials under the environment of high heat flux can't realize the protection function, a series of research [2][3][4][5][6] at home and abroad were carried out. Therefore, in order to meet the strict requirements put forward to the thermal protection materials of the new high-speed shuttle which works under harsh aerodynamic heating environment, a kind of material which can maintain shape, stand high temperature resistant, absorb and dissipate heat is urgently needed.…”

To improve the heat absorbed and scattered properties of quartz fiber tile, porous phenolic resin impregnated quartz fiber tile composite for ablator and thermal insulator was prepared by impregnating the quartz fiber tile with ethanol solution of phenolic resin, and then drying and cured. The phenolic resin impregnated quartz fiber tile ablative composite is a new heat protection composite material with lower density, lower heat conductivity and low mass ablation. It can be used as the widespread thermal protection system of the aero craft in the high heat flux, high temperature and extreme condition. The thermal property and ablation property of the composites were studied respectively. The ablation property of PICA was evaluated by the oxyacetylene ablation experiment. The microstructure morphology of specimen before and after ablation was viewed by SEM. The thermogravimetric analysis of the ablator was taken from room temperature to 800°C.
