The energy absorption characteristics of a number of dilatant suspension systems were evaluated using a modified pendulum impact tester. Two systems which were found to have superior impact energy absorption properties are 50 corn starch 2 SPAN 20 in a concentrated 26.5 NaCl solution and 70.5 glass microbeads 29 mu in water. The impact properties of all the dilatant systems were found to be significantly better than currently available ejection seat cushion materials. A qualitative correlation between the impact parameters measured in this investigation and the forces experienced during simulated ejection tests was made.
