Energy absorbing composition and impact and sound absorbing applications thereof

摘要

A substantially non-elastic incompressible composition, which substantially does not quickly self-level under standard operating conditions, includes: a suspending agent which reacts substantially as a solid when subjected to forces below a critical force, and which becomes substantially flowable when subjected to forces above said critical force. Aspects include compositions comprising one or more of ceramic microparticulates, flexible-walled microparticulates, celled macroparticulates, and fibers dispersed within the suspending agent, and energy absorbing applications thereof. Another aspect comprises thin-walled macrospheres containing a substantially non-elastic incompressible composition.

1. A substantially non-elastic incompressible composition which substantially does not quickly self-level under standard operating conditions, the composition comprising
a suspending agent having fibrous material dispersed within the suspending agent, wherein, upon being subject to incident energy, the fibrous material frictionally interact thereby imparting to the composition behavioral characteristics of a Bingham fluid such that the composition reacts as a solid when subjected to forces below a critical force, and which becomes flowable when subjected to forces above said critical force, and the composition absorbs incident energy.
