The behavior of a heat-protective ceramic composite material based on ZrO₂ fibers in a concentrated solar energy flux under conditions of a strongly nonequilibrium temperature and light field is demonstrated. A change in its structure and morphology depending on the heat treatment temperature is displayed. During an experiment the maximum surface temperature of a specimen based on ZrO₂ fibers reaches 1600°C, which is significantly lower than the operating temperature of materials based on ZrO₂. As a result of a concentrated flow of solar energy on heat-protective material based on ZrO₂ fibers, sintering, shrinkage, deformation, and fracture effects are observed, and the material loses its physical, mechanical and heat insulation properties.

证明了基于 ZrO ₂纤维的隔热陶瓷复合材料在强非平衡温度和光场条件下在集中太阳能通量中的行为。显示了其结构和形态随热处理温度的变化。在实验过程中，基于 ZrO ₂纤维的样品的最高表面温度达到 1600°C，明显低于基于 ZrO ₂材料的工作温度。由于太阳能集中流在基于 ZrO _{2 的}隔热材料上 纤维，观察到烧结、收缩、变形和断裂效应，材料失去其物理、机械和隔热性能。
