Sapphire fiber's abstrcat

Sapphire fibers have garnered significant attention due to their exceptional mechanical, thermal, and optical properties, making them promising candidates for various high-temperature applications. In this study, we present a comprehensive characterization of sapphire fibers, focusing on their microstructure, mechanical strength, thermal stability, and optical performance. We employ scanning electron microscopy (SEM) to investigate the microstructural features of the fibers, revealing their crystalline structure and grain boundaries. Mechanical testing, including tensile and flexural experiments, is conducted to evaluate the strength and flexibility of the fibers under high-temperature conditions. Thermal stability is assessed through thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), elucidating the decomposition and phase transitions of sapphire fibers at elevated temperatures.
