CRANE-84945
Determining the penetration potential of munition projectiles into human tissue is very common but the existent methods does not replicate the significant resistance that human skin provides. Common testing materials include animal skin, cling wrap, and natural rubber. These substitutes are unhygienic, too weak to simulate human skin, or the properties vary within one sample.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed, designed, and patented a skin and tissue simulant for munitions testing that replicates the significant resistance that human skin provides to prevent munition projectiles from penetrating into human tissue. This technology includes a gelatin composite block and an ether based cast polyurethane sheet. The gelatin composite block acts as the tissue simulant and the sheet acts as the skin simulant to determine the potential a given munition projectile has for penetrating skin. This new and improved skin and tissue simulant is an advancement over old testing materials because it adds the resistance that is naturally present in a human body.

Advantages:
-Superior simulant with valid penetration evaluation
-More hygienic than typical simulants
-Consistent or with less variations in raw materials

Potential Applications:
-Medical testing
-Veterinary
-Hunting
-Weapons testing
