“…An ablative composite material was used with zirconia fibers due to its significant mechanical properties and resistance to high-temperature ablation. It revealed that with 30% of zirconium fiber content composite material showed 19.33 MPa of bending strength; also at the higher temperature over 1400 °C, due to eutectic melting reaction, a ceramic protective layer forms which offers bending strength of 13.05 MPa [235].…”

Composites have been found to be the most promising and discerning material available in this century. Presently, composites reinforced with fibers of synthetic or natural materials are gaining more importance as demands for lightweight materials with high strength for specific applications are growing in the market. Fiber-reinforced polymer composite offers not only high strength to weight ratio, but also reveals exceptional properties such as high durability; stiffness; damping property; flexural strength; and resistance to corrosion, wear, impact, and fire. These wide ranges of diverse features have led composite materials to find applications in mechanical, construction, aerospace, automobile, biomedical, marine, and many other manufacturing industries. Performance of composite materials predominantly depends on their constituent elements and manufacturing techniques, therefore, functional properties of various fibers available worldwide, their classifications, and the manufacturing techniques used to fabricate the composite materials need to be studied in order to figure out the optimized characteristic of the material for the desired application. An overview of a diverse range of fibers, their properties, functionality, classification, and various fiber composite manufacturing techniques is presented to discover the optimized fiber-reinforced composite material for significant applications. Their exceptional performance in the numerous fields of applications have made fiber-reinforced composite materials a promising alternative over solitary metals or alloys.

“…Depending on the hyperthermal environment in which these materials must work, many types of formulations have been developed. Up to now, a wide range of fibers, , powdered fillers, − and nanosized reinforcements − have been added to the neat matrix to improve the ablation and oxidation resistance of these materials. In most cases, attention was focused on the influence of specific fillers on the ablation performance of composites.…”

Ablative materials will behave differently when cruising under different hyperthermal environments. Herein, liquid silicone rubber-based composites were employed as a model system to investigate the response behavior of ablative materials under different hyperthermal environments. The computational fluid dynamics simulation was used to examine the flow field of oxyacetylene flame under different heat fluxes. Results indicated that oxyacetylene flames with different heat fluxes have almost identical temperature distributions when the ratio of O2 and C2H2 is fixed, but the scouring force of the gas flow increases significantly with increasing heat flux. The ablation performance decreased when the heat flux increased from 1 to 5 MW/m2, and the ablation mechanism is mainly attributed to the hybrid coupling between mechanical denudation and oxidative erosion. The ceramization reaction to form SiC tended to occur under an inert atmosphere. In addition, the carbon fibers locating on the periphery of the core region tended to assume an orientation state with the progression of the ablation process. This work elaborated the influence of heat flux intensities on the ablative behavior of liquid silicone rubber composites, which also served as a reference to developing other types of ablative materials.

“…Carbon/Carbon (C/C) ablative materials are well known non-charring ablators which are often employed in the nozzles of rockets [13]. Charring ablative materials consist of an organic resin and one or more reinforcement phases and they guarantee an efficient heat removal thanks to several mechanisms: for phenolic resins, when temperature reaches about 300 °C, the endothermic pyrolysis reaction takes place guaranteeing energy absorption [14][15][16][17]; pyrolysis gasses are produced during the reaction and they absorb part of the heat by warming up themselves and, because of a pressure gradient, they flow in the boundary layer forming a barrier against convective heat exchange, this phenomenon is called blockage effect [2,[18][19][20]]. An ablative thermal protection system needs to satisfy different requirements: i) it has to protect the structure of the reentry vehicle and the payload from overheating; ii) the total required mass need to be as low as possible; iii) the recession of the shield has to be controlled in order to have predictable variations of the mass and shape of the vehicle [21].…”

Ablative materials represent a widespread solution for shielding space vehicles from overheating during a reentry phase in atmosphere where the high heating fluxes and the consequent high temperatures cannot be compatible with the vehicle structure and with the safety of the payload and/or the crew. In this work, two different kinds of carbon-phenolic ablators with a density of 0.3 g/cm3 were manufactured and their mechanical and thermal properties were experimentally evaluated. The thermal protection performances of the developed ablators were assessed in a hypersonic plasma wind tunnel facility, setting representative enthalpy and heat flux conditions (6 and 13 MW/m2), consistent with atmospheric reentry missions from high energy orbits. Data of the experimental tests were compared with the results obtained by a finite element model built up for these materials with the commercial software SAMCEF Amaryllis. All results enlighten the good performances of the ablators under severe heat flux conditions and outline their operating limits.
