“…SiC is an inert and very high melting point material; hence, the direct deposition of SiC by electron beam, laser, plasma, or thermal on a substrate are extremely challenging, and hence the precursor route was followed using chemical vapor deposition technique to coat SiC on a desired substrate including a carbon nanotube . We followed a solution-based coating technique to deposit a very thin layer of soluble SiC prepolymer, PCS on the surface of nanotube, and then annealed under an inert atmosphere and elevated temperature to convert the PCS to SiC.…”

A scalable process has been demonstrated for the controlled functionalization and positional controlled buckling of multiwalled carbon nanotube (MWCNT) by selectively masking the nanotube surface with chemically inert and thermally stable ceramic material. A uniform thin layer of soluble ceramic precursor, polycarbosilane (PCS), was first coated on MWCNT by the modified solution-based coating technique. The discrete silicon carbide (SiC) islands were then produced on nanotube surface during annealing at high temperature. The size and distribution of SiC islands on the surface of nanotube could be topologically regulated by controlling the thickness of PCS layer on MWCNT. The modulated surface of MWCNTs was then exploited for the site specific functionalization by guiding the incoming functional groups to the exposed surface. By optimizing the openings of the exposed surface of MWCNTs, the degree of chemical modifications could be tailored make. The controlled screening of nanotube surface has also been utilized for the physical modifications like selective buckling of tube walls by impinging high-energy ions on MWCNTs where the position of bending under irradiation fluence could be customized by the degree of passivation of the nanotube surface.

“…Nanostructures if reinforced into a carbon matrix lead to improved fracture toughness and interfacial bonding of C/C composites via toughening mechanisms, delamination, bridging, and crack deflections. − Additionally, tailoring the carbon matrix with nanostructures enables significant improvements in ablation and oxidation of C/C composites . Results of carbon/phenolic composites dispersed with carbon nanotubes show improved shear strength and flexural strength at room temperature .…”

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.
