ABSTRACT: The
paper presents the results of studying graphite plastics based on
heat-resistant polyamide by thermogravimetric analysis (TGA), as well as the
determination of mechanisms and kinetic parameters by the Koats-Redfern method.
Based on the results of the thermal analysis, the mechanisms and kinetic parameters
of the thermal destruction process were determined, namely: graphite injection
increases the heat resistance of graphite plastics by 2 (graphite content 10%
by weight) - 22% (graphite content 50% by weight) and reduces the activation
energy of the process thermal destruction almost 2 times. This makes it possible to improve the technological
parameters for the production of polymeric composite materials, which are
limited by a narrow interval between the flow temperatures and the thermal
destruction of phenylone C-2.
