Abstract

Biological materials are often viewed as composites, consisting of weaker components arranged hierarchically, leading to exceptional mechanical capabilities that are challenging to replicate in synthetic materials. Natural shape and structure develop through the process of striving for improved performance. This paper will provide a summary of observations from experiments conducted on a composite material designed to closely mimic a sophisticated multifunctional biological structure. The Split Hopkinson Pressure Bar (SHPB) was utilized to test strain rates ranging from 102 s-1 to 104 s-1, providing reliable and comprehensible data for analyzing the behavior of the composite material at high strain rates. The Split Hopkinson Pressure Bar (SHPB) device is frequently utilized for evaluating metals and other materials with high strength and mechanical resistance. This study will detail the changes made to a standard Split Hopkinson Pressure Bar (SHPB) apparatus for testing low impedance materials. An aluminum sample was seen to lose its specific stiffness as impact strain rate increased, but the produced material continued to improve.
