SiO2 aerogels have garnered significant attention for thermal insulation applications due to their exceptional hydrophobicity and resistance. However, the organic functional groups enabling introduce flammability concerns, limiting safe implementation in high-temperature environments. This study presents a novel TiO2 doping strategy (SA/TiO2) that simultaneously enhances safety while preserving material's intrinsic advantages. The optimized SA/TiO2 composite demonstrates remarkable fire resistance, achieving 44% reduction gross calorific value (GCV) 25.4% decrease total heat release (THR) compared conventional aerogels. Thermogravimetric analysis reveals substantial stability improvements, with incorporation elevating initial peak decomposition temperatures by 207 °C 167 °C, respectively. When integrated into fiber-reinforced aerogel composites, 10% TiO2-doped formulation achieves an ultra-low GCV of 2.75 MJ/kg maintaining superior performance (~18 mW/m·K). Notably, stability, retaining minimal conductivity 25.5 mW/m·K at 600 °C. titanium dioxide phase effectively attenuates radiation transmission matrix's nanoporous architecture, thereby synergistically enhancing both capabilities demanding operational
