  • In order to investigate the effect of different polymer materials as energy gathering tube tubes on energy gathering blasting, Uniaxial compressive experiments on different polymer materials under quasi-static conditions were conducted using an electro-hydraulic servo press and a 50 mm diameter Split-Hopkinson Pressure Bar. The static and dynamic mechanical properties, longitudinal wave velocity, energy dissipation and the deformation characteristics were studied. The results show that the maximum difference in wave impedance and quasi-static uniaxial compressive strength between different polymer materials reaches 42.5% and 312.3%, respectively. Under the impact load, the stress-strain curves of different polymer materials exhibit rebound phenomenon at the end of the curves, and the peak stress of PVC material is relatively higher among the six polymer materials under different impact pressures. From the analysis of energy transmission, dissipation rate and unit mass dissipation energy, PVC material has the highest energy transmittance among the six polymer materials, while energy dissipation and unit mass dissipation energy are the lowest. From the perspective of rock blasting, the absorption impedance ratio and incident energy are introduced for fitting analysis. The correlation coefficient between the fitting curves of PVC and PC materials is relatively high, which is more in line with the description of energy transfer during explosive explosion. Finally, based on all the analyses, it is believed that PVC material is the most suitable polymer material among the six types used in the experiment as a pipe material for energy gathering tubes.
