“…To provide overcoming of speeds of five and more machs by aircrafts, the urgent problem of protection of promising super heat-resistant carbon-carbon composites (CCC) and carbon-ceramic composites (CcC) against high-temperature oxidation and erosion loss has to be solved. There are several lines of protection, such as inhibition of composite material matrices by antioxidants [1][2][3][4] or deposition of heat-resistant coatings onto the reinforcing fibers [5][6][7][8]. However, deposition of coatings onto the work surfaces of parts contacting with oxidizing media [9][10][11][12][13][14][15][16][17][18][19][20][21][22] seems to be the most efficient.…”

The authors present the results of investigations of degradation processes that occur in the structure of heat-resistant coating of the Si-TiSi2-MoSi2-B-Y system in hypersonic flows of air plasma. It is found that coating operating capacity at surface temperatures Tw ≤ 1820÷1830°C is provided by the structural-phase state of its microcomposite main layer and formation on the coating surface of a heterogeneous passivating protective film. It is based on borosilicate glass reinforced by rutile microneedles. The mechanism of coating destruction at Tw ≥ 1850÷1860°C is erosion loss of oxide film as well as generation and growth of gas-filled cavities at the "coating main layer–oxide film" interface. As the pressure of saturated vapor of gaseous oxidation products (SiO, CO, MoO3 and B2O3) exceeds that of the ambient, the oxide film integrity is disrupted and oxidation process becomes active. The rates of erosion loss and sublimation grow as operating temperature increases and ambient pressure decreases.

“…In regard to sizing, in the presence of fibres, retardation of the main crack and an increase in fracture work because of the debonding of fibre and matrix pull out can be possible due to the dissipation mechanism of main energy under mechanical load [35]. It is important to ensure good adhesion of coating onto fibre (in this limiting case; chemical bonding) for resisting the fibre oxidation, otherwise the chance of fibre getting deboned and pull out from the matrix will be higher [15,[36][37][38][39][40].…”

Carbonaceous Materials Coated Carbon Fibre Reinforced Polymer Matrix Composites

Carbon fibre reinforced polymer composites have high mechanical properties that make them exemplary engineered materials to carry loads and stresses. Coupling fibre and matrix together require good understanding of not only fibre morphology but also matrix rheology. One way of having a strongly coupled fibre and matrix interface is to size the reinforcing fibres by means of micro- or nanocarbon materials coating on the fibre surface. Common coating materials used are carbon nanotubes and nanofibres and graphene, and more recently carbon black (colloidal particles of virtually pure elemental carbon) and graphite. There are several chemical, thermal, and electrochemical processes that are used for coating the carbonous materials onto a carbon fibre surface. Sizing of fibres provides higher interfacial adhesion between fibre and matrix and allows better fibre wetting by the surrounded matrix material. This review paper goes over numerous techniques that are used for engineering the interface between both fibre and matrix systems, which is eventually the key to better mechanical properties of the composite systems.

“…Currently, there are various methods to protect CCM from exposure to oxygen-containing environments, including: − management of carbon structure and use of its various modifications [11][12][13]; − inhibition of composites matrix by antioxidants [14][15][16][17][18][19]; − application of heat-resistant coatings on reinforcing fibers [20][21][22]; − application of coatings on surfaces in contact with oxidizing environments [21,[23][24][25][26][27][28][29][30][31][32].…”

Modern approaches to the creation of single-layer and multi-layer high-temperature coatings for the protection of heat-resistant carbon-containing composite materials from oxidation and erosion in the high-speed fluxes of oxygen-containing gases are analyzed. Particularly have been outlined the heat-resistant coatings, the main components of which are either super refractory transition metal borides (ZrB2, HfB2, TiB2) with the addition of carbides (SiC, ZrC, HfC, TiC, TaC), silicides (MoSi2, TiSi2, ZrSi2, TaSi2, WSi2) and nitrides (HfN, ZrN, TiN), or refractory oxides (HfO2, ZrO2), or more complex synthetic compositions based on oxide ceramics. The results of fire gas-dynamic tests of coatings of perspective compositions are presented. The potential architecture of ultra-high-temperature coatings with high efficiency of protective action is justified.
