THE STUDY OF RHEOLOGICAL PROPERTIES AND KINETICS OF THE CHEMICAL NETWORK FORMATION IN THE HIGH ENERGY SYSTEMS

摘要

Physical mechanical characteristics of high energy condensed systems (ECS) are specified in the first place by the properties of a polymer base, namely by the three-dimensional network of chemical bonds. Destruction of the ECS polymer base takes place eventually at long storage, due to the stresses existing in a charge as well as the hydrolysis conditioned by a residual moisture of the components and various uncompleted side reactions accompanying ECS curing. At present there is a number of technological approaches for stability of mechanical properties of the high energy condensed systems favoring the increase of the charge shelf-life up to 12... 15 years to be attained. The development of the ways of a new ECS class creation with a shelf life 30...40 years will result in a qualitative increase of the performance characteristics of existing and prospective objects of defense technology.
