Description

Soft tissue injuries have made a significant impact on almost every contact sport played and age group in the United States. Lesser publicized soft tissue injuries also occur in the growing U.S. elderly population. Limiting force, rotational acceleration, and momentum transfer is critical to reducing injury and trauma during these low to medium velocity (1 m/s to 12 m/s) impacts. The next generation of impact mitigating materials requires the optimization of material properties, rate sensitivity, and architecture across a broad range of strains and strain rates. A new material measurement framework is required to guide design and evaluate performance on a level playing field. NIST is developing novel metrologies to characterize the dynamic behavior of impact mitigating polymers, elastomers fibers, and composites under multiaxial loading. This project will couple concepts in energy dissipation, force transfer, phase transitions to models and materials by design concepts to produce new materials and architectures to protect the body from blunt injury.
