Title:
SMART PADDING SYSTEM UTILIZING AN ENERGY ABSORBENT MEDIUM AND ARTICLES ABTAINABLE THEREFROM
Document Type and Number:
WIPO Patent Application WO2000046303
Kind Code:
B1
Abstract:
The present invention relates to an energy absorbent medium which is compliant and conformal in the absence of an applied force, and stiffens in proportion to the rate of an applied force to dissipate energy. A polymeric based material composition comprising the medium offers absorption and dispersion of impact energy that is directly proportional to the rate of force applied. The polymer composition medium comprises a blend of a polymer, a lubricant and a filler to produce a conformal absorbent which exhibits dilatant (shear thickening) characteristics under high rates of force or stress. The novel medium comprises a dilutent extended crosslinked viscoelastic polymer composition. The polymer has reformable sacrificial chemical bonds which are preferentially broken under a high rate of deformation and which reform under static conditions. Typical applications of this medium include absorbent for sports padding, athletic equipment, motor vehicle seats, bulletproof vests, medical equipment, industrial equipment, weaponry, and athletic playing fields.
