How do ceramic fibers affect the lifetime of materials in high-temperature environments?

Ceramic fibers significantly enhance the lifetime of materials in high-temperature environments by providing thermal insulation and resistance to thermal shock. They reduce heat transfer, which helps maintain lower operating temperatures within the material, thereby slowing down the rate of degradation caused by heat. Additionally, ceramic fibers can improve mechanical strength and structural integrity at high temperatures, preventing material failure due to thermal stress. Their chemical stability also prevents reactions with the surrounding environment that could lead to material degradation. Overall, the incorporation of ceramic fibers can extend the service life of materials in harsh, high-temperature conditions by protecting them from the damaging effects of heat and maintaining their structural properties.
