NSWCDD Report: Mitigating Blast and Shock Using Advanced Materials

The Naval Surface Warfare Center, Dahlgren Division (NSWCDD), in collaboration with Naval Surface Warfare Center, Carderock Division (NSWCCD), and Naval Undersea Warfare Center, Division Newport (NUWCDIVNPT); conducted experimental and analysis research to produce layered polyurea/woven crimp-graded composite panels optimized for blast and fragment impact protection.

NSWCDD’s Shock Physics Facility, shown in Figure 1, consists of a single stage 40mm bore gas gun with associated hardware and electronics that uses helium or nitrogen gas to accelerate objects to speeds of 60–975 m/s. The facility provides a multipurpose experimental capability used for a variety of applications including characterizing and optimizing materials and components that must perform in intense mechanical impulsive environments such as projectile, armor, and explosive ordnance applications; shockwave equation-of-state measurements on materials (for computational design and simulation); and precision impacts over a wide range of impact speeds into full-scale target configurations to measure deformation, penetration, and reactive energy release.

Naval Surface Warfare Center, Dahlgren Division, is collaborating with Naval Surface Warfare Center, Carderock Division, and Naval Undersea Warfare Center, Division Newport, to produce layered polyurea/woven crimp graded composite panels optimized for blast and fragment impact protection. The intent is to develop blast and impact resistant elastomeric coatings and woven fabric-reinforced polymer composites for use in numerous structural and survivability applications as well as applications where improved lightweight blast and impact protection is a necessity. This report documents the NSWCDD light gas gun experimental portion of this effort.
