Abstract

The stress-strain curves of glass-fiber reinforced silica aerogels (GRSA) are obtained by carrying out the quasi-static and split Hopkinson pressure bar (SHPB) experiments. The dynamic compression process of experimental materials are precisely controlled with the "frozen strain" method, and the effects of relative density, diameter and strain rate on dynamic compressive mechanical properties are discussed. Then the compressed samples are observed with scanning electron microcopy (SEM). Considering the Sherwood-Frost constitutive relation and contribution of gas to the strength of the material, the macroscopic phenomenological constitutive relation of this material is developed.
