Abstract
Abstract—The relationship between the Nb–Si–Ti matrix and single-crystal α-Al2O3 fibers with a W barrier coating at the interphase matrix–coating–fiber boundaries is studied. It is established that at 1300°C the bending strength of the composite material reinforced with fibers with a coating is 2 times higher than that of the matrix and is 1.3 times higher than the strength of the composite material reinforced with fibers without a coating.
