Non-Newtonian Flow for Human Impact Protection.
Abstract
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.
