Multiscale Mechanical Characterization of Biomimetic Gels for Army Applications
Abstract
Ballistic gelatin often serves as a tissue surrogate for impact testing. Unfortunately, this material exhibits issues such as mechanical instability at room temperature and is difficult to structurally modify. A material system that is not as sensitive to these issues is styrene-isoprene triblock copolymer gels. In this work, two such copolymer gels were compared to ballistic gelatin via mechanical behavior evaluation using both macro-scale and micro-scale measurements. Both copolymer gels were found to have a greater degree of thermal stability than ballistic gelatin, and results based on mechanical evaluation show that the copolymer gels may be suitable as a replacement for ballistic gelatin.
