Abstract : Sorbothane, a high density polyurethane material with unusual displacement properties, is presently used extensively as a cushioning material for the human body in medical and sporting applications. This study was undertaken to consider possible packaging applications for this unique material in providing cushioning and shock isolation for Air Force equipment. Various structural configurations of the material were subjected to dynamic cushioning evaluation. In addition the material was evaluated for its shear strength characteristics for possible use in shear mount type shock isolators. Results of this evaluation indicate that dynamic cushioning characteristics of Sorbothane are only slightly better than some commonly used materials. The high density and cost of Sorbothane makes this material quite impractical as cushioning material in comparison with the commonly used materials. The low shear strength of Sorbothane and its tendency to tear under shear loading makes it unsuitable for use in shock isolators. (Author)
