摘要
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.
