  Abstract

Aramid fiber has superior tensile strength compared to existing organic fibers, so it is used in tire cords and aerospace fields. Because copolymerized aramid uses an organic solvent in the production process, it has great advantages in terms of process safety and manufacturing environment stability compared to the existing production process using sulfuric acid as a solvent. However, in the case of copolymerized aramid, a stretching rate 8 to 12 times higher than the stretching process is required for high mechanical properties. In order to stretch 8 to 12 times, a high temperature of over 400 to 600 degrees is required. CAE is utilized to optimize the thermal stability and flow of the ultra-high temperature stretching process. For high stretching of 8 to 12 times, a three-stage stretching chamber with a temperature of 500 °C or higher is used. Thermal analysis, structural analysis, and flow analysis were performed to maintain the thermal and structural stability inside the high temperature chamber above 500 °C and the flow stability of hot air. Through heat distribution and flow analysis, various problems that can occur in the stretching process are identified, and various stretching process types and process conditions are proposed to prevent them. Based on the proposed gap and air heater conditions, a high temperature stretching process of over 500 degrees can be produced and used to produce actual organic fibers.
