“…One feasible and effective strategy to promote the reinforcement of composites is through chemical functionalization of nanofillers [20][21][22]. Among chemical functionalization methods, grafting molecules and/or polymer chains onto the surface of graphene sheets was studied for many polymers [23][24][25].…”

Catastrophic breakdown that occurs during the flight of supersonic vehicles demands more focused research in the insulation of rocket engines. At present, optimization of polymeric ablatives as viable insulation for solid rocket motor casing has a prominent role in the successful mission of rockets. Among polymers, elastomer serves an imperative part. Comprehensive investigations were disclosed, especially in the elastomeric heat shielding materials with various reinforcing agents. In this paper, research progress of mostly used elastomers is reviewed, and a circumstantial understanding about the features of ablation and insulation has been validated. 2-4 Therefore, to protect the vehicle from miserable failure of spacecraft, some design features are added to cope with the aerodynamic heating. 5Thermal protection system (TPS) materials impart heat shield to protect the structure, aerodynamic surface and the payload of missiles, and those vehicles interacting with the hypersonic environment. 6,7 Polymeric ablative materials serve to effect as TPS that defends space vehicles and probes during the atmospheric entry; they are effective to produce passively cooled rocket combustion chambers 8 and to render insulation to the solid rocket motors (SRMs) at high temperature. [9][10][11] Although some nonpolymeric materials such as inorganic polymers/ceramics or metals have been used as ablative TPS, polymeric ablatives represent the most flexible category of ablatives. In contrast to the inorganic polymers, polymer ablatives have more inborn benefits: high-heat shock resistance, lower density, good mechanical strength, and thermal insulation capabilities. 12The broad range of heat shielding materials (HSMs) for rocket motor casing is produced from reinforced thermosets or elastomers. [13][14][15][16][17][18][19] The most assuring material for the HSM for rocket motors is the elastomers, which can be produced as rubbers, foamed rubbers, or fiber-reinforced composite materials. On the grounds of lightweight, low thermal conductivity, stability in the mechanical and thermal stresses during the operation, elastomeric HSMs (EHSMs) can find relevance in the insulation of SRM casing where thermal insulation is a prime necessity. They do not possess the ability to form cokes without the introduction of special additives due to the linear chain structure of elastomers, thus no solid carbonic residue on thermal decomposition.Also, elastomers have high elongation at break and the capacity to withstand the mechanical and the thermal stresses during the manufacturing and in use. 20This review puts the elastomeric materials as ablative insulators for SRM into frame and would confer the readers the progress that has been attained in developing relatively low surface eroding and ablative insulating systems for SRM. These systems can be used to manufacture variety of ablative TPS systems for rocket motor casing application and would provide an idea regarding the composite system that would behave elastomeric as well as ablative.

“…Since the first observation of carbon nanotubes (CNT) in 1991 by Iijima [7] and the identification of their distinctive mechanical, thermal and electrical properties, the approach of using CNT/polymer composites to improve the polymers' functions has been popularly taken [8][9][10][11][12]. However, carbon nanotubes frequently aggregate into bundles due to their inherent van der Waals interactions among the CNTs.…”
