Abstract

The process of destruction of a polyamide composite with different porosities under dynamic loading has been studied. Graphical dependences of pressure in polyimide with varying degrees of porosity on mass velocity are obtained; impact adiabats of the same polyimide samples in D-u coordinates are calculated. It has been established that irreversible physico-chemical transformations of matter at the shock wave front occur in the polymer composite under extreme conditions.

Keywords

Polyamide composite, dynamic pressure, Gruneisen function, impact adiabatic.
