\n Aramid fiber molecules have strong covalent bonds along the direction of the aramid fiber. The orientation and arrangement of the molecular chains make the aramid fiber have highly oriented crystalline microdomains. At the same time, there are some defects and gaps. The existence of these defects and gaps is easy to The stress concentration points formed when the fibers are used determine the maximum strength that aramid fibers can achieve. Therefore, the stability and improvement of fiber properties depend to a large extent on the control of defects and micropore formation during spinning and fiber solidification. To this end, the Ministry of Science and Technology has set up the 973 project to conduct in-depth research on the formation mechanism, evolution rules and control methods of micro-defects in the fiber caused by various external conditions during the molding process of aramid fiber (project number 2011CB606103). Through the theoretical structure The simulation formed and the engineering inspection of the simulation process have achieved relatively obvious results, effectively promoting the improvement of my country’s aramid industry. \ufffd<\/p<\/p>\n
