Abstract:
Hot-spot temperature in shock compression of a mixture of epoxy resins with glass hollow microspheres is estimated. The obtained hot-spot temperature of 3200 K at a shock pressure of 20 GPa significantly exceeds the temperature of shock-loaded homogeneous epoxy resin, which at this pressure is in the range of 1100–1400 K. The time characteristics of the radiation generated during viscoplastic compression of a monolayer of hollow microspheres in an epoxy matrix at a pressure of 9, 20, and 29 GPa were determined by an optical pyrometer. Experimental data are shown to be in good agreement with estimates based on the viscoplastic deformation model.
Keywords:
