abstract


The subject of research is the methods for measuring the rheological and tribological properties of materials processed by extrusion.

Methods for measuring the coefficients of external and interparticle friction, the coefficient of lateral pressure, compaction, viscosity, the pressure of the flow of a medium through a cylindrical capillary, and structural strength are considered. The set of equipment for studying the technological properties of materials, a capillary viscometer for determining the rheological properties of plastic materials, a plastomer with a conical indentor for studying the structural strength of materials are considered. 

Described methods, devices and equipment allow obtaining reliable experimental data necessary for calculating the shape and dimensions of the screw and forming head, and determining the modes of extruder operation. Given results can be used in the design of specialized equipment for screw extrusion of products made of composite materials.
