TIME SCALE HARDENING EFFECTS OF RUSAR ARAMID FIBER AT ELECTROMAGNETIC PROCESSING

The paper presents the preliminary statistical analysis of the hardening of Rusar aramid fiber depending on the length of the electromagnetic effects. The article shows that the effect of hardening quantitatively different for different clamping lengths in measuring the strength of filaments, and the processing time. The authors made statement about the formation of the strength properties as tensile of strength and modulus passes through some intermediate stage of state. An increase in the tensile strength by 11 % and modulus by 6 % were obtained on the clamping length of 20 mm. The statistically significant increase in the elastic modulus of 5,7 % was obtained on the clamping length of 40mm. These results are statistically significant.
