This paper describes achievements of the All-Russian Scientific Research Institute of Aviation Materials in the field of creating high-temperature heat-shielding, ceramic and metal-ceramic composite materials. The advantages and prospects of applying the developed materials in the manufacturing of structural elements of aircraft and friction joints are discussed. The synthesis features and basic properties of metal-ceramic composite materials based on light alloys, refractory metal matrices, ceramic composite materials for use in heavily loaded structural elements of modern aircraft are presented. The main achievements in the field of heat-shielding materials based on refractory oxide fibres are presented, along with their properties and application in new-generation aircrafts.

“…The ceramic matrix composites (CMCs) [2] reinforced with different types of fibers [3], including carbon ones, more often find their application in structures operating at high temperatures, an aggressive environment, multiple heat cycles, and high mechanical stresses [1].The fiber surface is usually modified to improve the physicochemical and physicomechanical properties of composites based on carbon fibers. For example, the coating deposited on carbon fibers can increase their physicochemical properties, such as thermal oxidation resistance [4].…”

The formation of a ceramic interfacial coating (IC) on carbon fibers by the polymer infiltration and pyrolysis (PIP) method with the use of polycarbosilane and oligovinylsilazane as the preceramic polymer precursors is discussed. It is shown, that the use of a preceramic polymer concentration higher than 3 wt % results in the formation of clumps with an uneven distribution of the ceramic matrix. The use of a preceramic polymer concentration lower than 3 wt %, an inert atmosphere, and time-temperature regime treatment, calculated for a steady heat release and mass loss, results in the formation of a uniform IC and leads to a high level of oxidation resistance of carbon fibers. The oxidation products of carbon fibers with the deposited IC are hollow SiO 2 structures.

“…Owing to high decomposition temperature, good mechanical characteristics, chemical inertness and the highest oxidation resistance among refractory carbides, SiC is the main and the most important component of many composite and ceramic materials for high-temperature applications [1][2][3][4][5][6][7][8][9]. Silicon carbide is used for production of wear-resistant parts due to its high hardness [10,11].…”

High-porous SiC ceramics (density 0.50-0.58 g/cm 3 , porosity 82-84 %, compressive stress at break 3.7-6.3 MPa) was prepared by means of polymeric technology and natural raw material (diatomite powder, ''Biosilica'' grade) at the temperature of carbothermal synthesis (1400°C). It was shown that the main phase was silicon carbide with a small (\5 %) impurity of FeSi; SiC crystallite size was found to be 23-30 nm. Using scanning electron microscopy, X-ray computerized microtomography, and dynamic light scattering in aqueous suspensions of powders obtained at ultrasonic exposure, it was shown that SiC nanoparticles in the samples were aggregated to a great extent. The degree of aggregation strongly depends on SiO 2 -C ratio in the starting samples.
