N2 - The dynamic behaviors of glass fiber reinforced silica aerogel and the Mg/aerogel composites are experimentally investigated using spilt Hopkinson pressure bars. For the purpose of comparison, dynamic responses of hydrogel are also investigated. Incident wave shaping experiments are designed to investigate the shaping effects of aerogel and Mg/aerogel structures. Results show that the fiber reinforced aerogel exhibits significant strain rate strengthening and strain hardening behavior. The strength of the investigated aerogel exhibits evidently size effect: strength of aerogel shows an increasing tendency with the size of sample due to the special nano-porous network structure of aerogel. The incident wave shaped by the composite structure of Mg/aerogel is obviously weaker than that of single magnesium alloy or aerogel, indicating a better protective capacity of Mg/aerogel composite structures.
