Energy absorbing composition and impact and sound absorbing applications thereof

A substantially non-elastic incompressible composition which substantially does not quickly self-level under standard operating conditions, the composition comprising:

• a suspending agent which 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
• particulates dispersed within said suspending agent;
• wherein the composition absorbs incident energy.

A method of manufacturing a substantially non-elastic incompressible composition which substantially does not quickly self-level under standard operating conditions, the method comprising:

• mixing glycerin with water at high shear to form a first interim mixture;
• adding an aqueous solution of acrylic acid polymer and hydrocarbon distillate containing ammonium hydroxide to said first interim mixture while mixing at low shear to form a second interim mixture;
• adding celled macroparticulates to said second interim mixture while mixing at low shear to form a third interim mixture;
• and
• adding ceramic microparticulates and flexible-walled microparticulates to said third interim mixture while mixing at low shear to form said composition.

A system for manufacturing a substantially non-elastic incompressible composition which substantially does not quickly self-level under standard operating conditions, the system comprising:

• means for mixing water with glycerin at high shear;
• means for mixing an aqueous solution of acrylic acid polymer and hydrocarbon distillate containing ammonium hydroxide with said water and said glycerin at low shear;
• means for dispersing foamed polymer particulates in said water and in said glycerin at low shear;
• and
• means for dispersing ceramic microparticulates and flexible-walled microparticulates in said water and in said glycerin at low shear.
