CARBON PLASTIC BASED ON ALIPHATIC POLYAMIDE

Abstract

The influence of the processing temperature on the thermal, thermophysical, physico-mechanical, and tribological properties of carbon fiber based on aliphatic polyamide PA-6.6 was studied. It was established that the optimal complex of operational characteristics has carbon plastic pressed at a temperature of 518K. Reinforcement of PA-6.6 with carbon fiber material allows to significantly improve the thermal and thermophysical properties of the polymer. Carbon fiber has high values of heat resistance and thermal conductivity (0.74-0.94 W/m ⋅ K), good strength indexes, and almost 6 times lower temperature coefficient of linear expansion compared to the original polymer. The low coefficient of friction and high wear resistance and the PV performance criterion of the developed material make it possible to recommend it for use as a material for structural purposes in the field of mechanical engineering.
