Research on reaction kinetics of MC polyamide 6/Kevlar fiber composites

The reaction kinetics of MC polyamide 6 and MC polyamide 6/Kevlar fiber composites was obtained by differential equations of nonisothermal kinetics and modified by considering the temperature field.The reaction activation energy of MC polyamide 6 and MC polyamide 6/ Kevlar fiber composites changed from(90.3 kJ/mol) and(102.4 kJ/mol) to(72.9 kJ/mol) and(80.1 kJ/mol) after modified,the frequency factor changed from 1.76×10~9 and 4.02×10~(10) to 1.26×10~7 and 9.18×10~7 accordingly,both of the treating activation energy and frequency factor were closer to the real system.KF could increase the value of activation energy and frequency factor for MC polyamide 6.The reaction orders of MC polyamide 6 and MC polyamide 6/ Kevlar fiber composites are approximately first-class.
