Abstract: The article presents the results of a study of the behavior of a composite material, a matrix based on an organic polymer filled with fibers of partially stabilized zirconium dioxide, under exposure to air at temperatures above $2000^{\circ}$C. The discovered phase and structural changes lead to the formation of a new, lowtemperature phase, while the fibrous structure of the material was maintained. The study makes it possible to evaluate the use of a composite material with an organic matrix reinforced with refractory zirconium oxide fibers under conditions of short-term exposure to extremely high temperatures.
