Elastomeric Polymer-by-Design for Blast-Induced Shock-Wave Management



The essence of this research is to mitigate shock through material design by both small-scale heterogeneity and anisotropy.  This work seeks to develop and verify rules and tools for creating elastomer-based composite materials with optimally designed nano-, micro-, meso-, and macro-scale compositions and characteristics to manage black-induced stress-wave energy over broad ranges of frequencies and amplitudes in order to:

  • Shield the interior of a chamber (e.g., helmets, vehicles) against harmful effects of blast-induced pressure-shear stress-waves
  • Eliminate and/or absorb these waves by:
  • Trapping and dissipating their kinetic energy
  • Pressure to shear conversion
