摘要

Detailed understanding of the response of confined energetic materials to different stimuli is critical to their design. This paper presents an experimental investigation of ignition mechanisms in Detasheet (a polymer-bonded explosive) when confined between copper plates and impacted at normal incidence with copper plates at velocities up to 600 m/s. High-speed photography and optical fibres are used to detect points of ignition and consequent reaction history. PVDF stress gauges are used to relate velocity of impact with pressure generated in the explosive A Hugoniot curve for detasheet has been plotted.
