“…The research Fig. 7 Exhaust duct made out of PyroSic papers have shown that the linear ablation rate of Z C-Ph composite has reduced by 79 % compared with the un modified C-Ph composite [35]. The ablation surface though at higher temperature during ablation process the back surface temperature is found to be lower by 100°C as compared to unmodified composites.…”

“…The research in this field has shown that the ablative rate has been higher as compared to Carbon fibres in C-Ph composites. The ablative resistance properties have been improved by adding modified phenolics in the C-Ph matrix [34][35][36][37][38][39]. The modification is obtained by treating with boric acid or POSS (Poly Oligomeric Silsequioxanes), or H 3 PO 4 .…”

The chapter on High Temperature Polymer Nanocomposites mainly covers the advancements made in the research on varied composite materials and their novel innovations for high temperature applications. The chapter begins with a prelude on existing polymers of thermoplastic or thermosets and also a combination of the two to exploit the dual advantage of both high temperature thermoplastics and thermosets. The polymer composites are developed and implemented for varied temperature regimes in the range of 120-250°C, 250-350°C specially suited for aerospace applications. Further research work is under progress to explore the material suitable for temperatures above 350°C. The initial section explains on the applicability of polymer composites having matrices such as either liquid crystalline polymer, cyanates, polyimides or bismaleimides which are reinforced with either the carbon, glass or aramid fibres especially continuous fibre which provides improved material and physical properties. The polymer-composites are assessed for performance of the matrices and the composites not only for their strength or stiffness but also for their resistance to cracking, minimum loss of weight, brittleness due to cross-linking and other properties that may degrade the performance of the composites over the long period of high temperature applications. This section mentions on the literature reviews having come up with research in progress on other types of resins for high temperature applications namely the oligomers such as the acetylene terminated polyimides or the norbornene terminated polyimides. The second section is concerned with the polymer-nanocomposites for high temperature applications. In this section, the role of nanofillers in the enhancement of composite properties is discussed. The various forms of nanofillers are the nanoclay, nanofibres, carbon

“…Addition of various nanoparticles such as nanosilica, montmorillonite (MMT), nanoclays, and polyhedral oligomeric silsesquioxane (POSS) with surface functionalization acts as thermal insulative elements for improving char layer integrity and toughness. Three phase composite system with heterogeneous composition (fiber reinforcement, matrix, and nanofillers) exhibits complexity in its ablation behaviour [4]. The scientific insights into the ablation and decomposition behaviour of the composite materials lead us to a trustworthy analysis of the composite performance at high temperature working environment.…”

Composite materials have been steadily substituting metals and alloys due to their better thermomechanical properties. The successful application of composite materials for high temperature zones in aerospace applications has resulted in extensive exploration of cost effective ablative materials. High temperature heat shielding to body, be it external or internal, has become essential in the space vehicles. The heat shielding primarily protects the substrate material from external kinetic heating and the internal insulation protects the subsystems and helps to keep coefficient of thermal expansion low. The external temperature due to kinetic heating may increase to about maximum of 500 ∘ C for hypersonic reentry space vehicles while the combustion chamber temperatures in case of rocket and missile engines range between 2000 ∘ C and 3000 ∘ C. Composite materials of which carbon-carbon composites or the carbon allotropes are the most preferred material for heat shielding applications due to their exceptional chemical and thermal resistance.

Ablative composites are highly endothermic sacrificial materials, which undergo ablation wherein the outer surface of the material degrades to form a carbonaceous layer, which isolates the underlying material from intense thermal‐heat‐flux environs. Successful utilization of thermosetting resins modified with varied inorganic fillers to tailor ablative polymer composites for thermal protection systems has accelerated extensive research for the development of new contemporary materials for vast space and defense applications. This article discusses various types of ablative materials, polymer composite‐based ablative materials, ablation mechanism, and applications of ablative materials. Resorcinol formaldehyde (RF) resins, which have a similar chemical backbone to the phenolic formaldehyde (PF) resins, possess several advantages which make it a contender for the next generation of ablative materials. The synthesis, testing, and characterization of RF resin‐based ablative polymer nanocomposites have also been presented in this article.
