Abstract

Abstract:

In recent years, the supercritical fluid microcellular foaming technology has gained much attention in the polymer material processing. Much research has been done on the foaming mechanism and the polymer material processing. The change of foam structure parameters, the sorption and diffusion of supercritical CO2 in propellants and the burning behavior of foamed gun propellants are studied according to the foaming mechanism. Combined with the burning behavior of foamed propellant, the application of foamed propellant in the charge technology is prospected, and the development direction of supercritical fluid foaming in the preparation of the foamed propellant is also put forward.

Key words: ordnance science and technology, supercritical fluid, sorption, diffusion, foaming, gun propellant, burning
