A Technique for Analyzing Rheological Properties of Fast-Curing Aluminoborophosphate Binder Based on Test Results Using a Brookfield CAP 2000+ Viscometer

This paper deals with the problem of porous prepreg preparation using impregnation under pressure for the production of composite structures that includes obtaining and utilizing binder viscosity diagrams as functions of time and shear rate (kinematic characteristic of the velocity field in the binder). A technique of constructing rheological models of fast-curing binders is developed based on test results using a Brookfield CAP 2000+ viscometer. The established rheological properties of aluminoborophosphate binder (ABPhB) as an object of the research are of significant interest in creating composite structures with an inorganic matrix that possesses properties of thermal stability, incombustibility and ecological safety.
