“…To improve the oxidation properties of carbon fiber, SiC is coated on the carbon surface to be used for solar-cell ingot-growing containers. Currently, SiC fiber has a small market due to high cost, but can exhibit robust behavior under high temperature and oxidative environment conditions [ 139 , 140 , 141 ]. The main properties of SiC fibers are presented in Table 9 [ 142 ].…”

In the last decade, synthetic fiber, as a reinforcing specialist, has been mainly used in polymer matrix composites (PMC’s) to provide lightweight materials with improved stiffness, modulus, and strength. The significant feature of PMC’s is their reinforcement. The main role of the reinforcement is to withstand the load applied to the composite. However, in order to fulfill its purpose, the reinforcements must meet some basic criteria such as: being compatible with the matrix, making chemical or adhesion bonds with the matrix, having properties superior to the matrix, presenting the optimal orientation in composite and, also, having a suitable shape. The current review reveals a detailed study of the current progress of synthetic fibers in a variety of reinforced composites. The main properties, failure modes, and applications of composites based on synthetic fibers are detailed both according to the mentioned criteria and according to their types (organic or inorganic fibers). In addition, the choice of classifications, applications, and properties of synthetic fibers is largely based on their physical and mechanical characteristics, as well as on the synthesis process. Finally, some future research directions and challenges are highlighted.

“…Ratnayake et al 17 prepared boron-doped yttriastabilized ZrO 2 surface coatings on polyacrylonitrile-based carbon fibers and examined the thermal behavior. Typical preparation processes for these coatings include chemical vapor deposition, 9 chemical vapor infiltration, 14 precursor infiltration and pyrolysis, 8,10 and sol-gel 11,12,[15][16][17] methods. In contrast, the sol-gel method requires a straightforward preparation process, low cost, and high suitability for coating on different substrates, which is a potential method for development.…”

In order to solve the shortcoming of fiber oxidation in a high‐temperature environment and improve the antiablative performance, yttrium silicate is coated on the carbon fibers’ surface by the sol‐gel process. In the present work, investigations of the ablation resistance of carbon fiber composites with yttrium silicate coatings (YS‐CFs) prepared by different sol contents and sintering temperatures are reported. The results show that YS‐CFs exhibit excellent ablation resistance in the oxyacetylene test with a heat flow of 1.5 MW/m2. The surface coating of carbon fiber is composed of a mixture of cristobalite, yttrium monosilicate, and yttrium disilicate. The best ceramic coating could be obtained by dipping 20% silica sol and 14% yttrium sol in turn and sintering at 1300°C. In this case, the linear and mass ablation rates reach the minimum values of .667 μm/s and 2.975 mg/s, respectively. YS‐CFs could be used as reinforcements for thermal protection materials in high‐temperature environments.
