INFLUENCE OF FULLERENE ON THE RHEOLOGICAL CHARACTERISTICS OF MELTS OF THE POLYAMIDE COMPOSITE FORMING THE STRUCTURE OF A SEMI-INTERPENETRATIVE POLYMER MESH

摘要

The time change in the melt viscosity of the polyamide composite forming at the final stage a polymer with the structure of a semi-interpenetrative polymer mesh has been investigated. To impregnate with the composite melt the carbon fiber for forming carbon-filled plastics, it is necessary to preserve the low viscosity of the melt for a long time. This is achieved by preliminary heat treatment of the composite and introduction of fullerene into it.
