Experimental investigation on mechanical properties of a fiber-reinforced silica aerogel composite

► Mechanical properties of fiber-reinforced aerogel were investigated by experiments. ► Compression tests were performed at both room and evaluated temperature. ► Temperature has great influence on compression behavior at strain above 0.5. ► Stress Relaxation Tests were carried out at both room and evaluated temperature. ► Stress relaxation mechanisms analyzed by Scanning Electron Microscope.
