| 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. |
