Abstract: 

The impact of the content of heat-resistant organic arcelon fiber on the thermophysical properties of aromatic polyamide phenylone C-1 in the temperature range of 323 to 548 K is considered in the article. It has been determined that the introduction of 5-10 wt % of the filler leads to the positive effect. It contributes to the increase of coefficients of thermal conductivity and thermal diffusivity 1.5-2 and 1.8-2.9 times respectively. It has been shown that with the same content of the filler, we can observe the reduction of specific heat discontinuity and temperature coefficient of entropy by 40-65 % and 23-65 % respectively in the comparison with phenylone. This is due to the interaction of the filler with a polymer matrix: structure formation at the "polymer-filler" interface by straightening and aggregation of the part of phenylone macromolecules in the interfacial layer.
