Abstract

High strain rate stress wave dissipation is essential for protecting personnel and structures from damage caused by shockwaves, which can lead to catastrophic failures in aerospace, defense, and automotive applications. Developing advanced materials capable of efficiently mitigating these dynamic forces is crucial for enhancing safety and durability. This study explores the development and evaluation of boronic ester crosslinked (BCN) gels for high strain rate stress wave dissipation. The BCN gels were synthesized through free radical polymerization and crosslinked via dynamic boronic ester bonds. These gels exhibit enhanced dissipation performance due to their unique ability to undergo reversible bond dissociation. The BCN gels demonstrate superior energy dissipation capabilities compared to conventional materials such as epoxy and polyurea, particularly at higher crosslinking densities. The gels possess self-healing and reprocessing abilities, adding to their versatility for long-term use and damage recovery. The results highlight BCN gels as a promising material for high-performance stress wave mitigation in dynamic environments.
