Abstract:In order to achieve non-contact visual sensing of the blunt impact field for ballistic protection devices, a self-responsive bionic target was established. Mechanoluminescence material (ZnS∶Cu), was used as the force-sensitive material and compounded with silicone rubber to prepare a responsive bionic skin. This skin was then combined with the bionic adipose prepared from Kraton polymer (hereinafter referred to as Kraton-based bionic adipose) to form the self-responsive bionic target. Quasi-static mechanical tests were carried out on the self-responsive bionic skin and Kraton-based bionic adipose, and their mechanical properties were compared with those of biological skin and biological adipose. Finally, the impact characteristics of the self-responsive bionic target were studied. The results indicate that the elastic modulus of the designed and synthesized bionic skin (ZnS∶Cu-5,ZnS∶Cu-10) at a strain rate of 0.10 s-1 differs from that of the skin of the human forearm by 5.33% and 1.33% respectively within the low strain region. The elastic modulus of the Kraton-based bionic adipose is close to that of the adipose tissue of the sheep′s hip region, with a deviation of 5.53%. This demonstrates the rationality of using the "mechanoluminescence material-silicone rubber-Kraton-based polymer" as the bionic target. The target exhibits a significant mechanoluminescence response under impact loading, with the luminescent intensity linearly correlated with the peak value of the shock wave. When the impact air pressure is 0.3 MPa, the relative error of the initial peak pressure of the obtained blunt impact field shock wave is 13.7%, indicating high accuracy. This shows that the self-responsive bionic target has great potential in real-time visual testing of shock wave fields experienced by soft tissues. The research provides a new idea for ballistic terminal testing methods.
