详细
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 SiO2 structures.
