|dc.description.abstract||Wet spinning of PAN solution is complicated process, which involves rheological and diffusional phenomena [1-3]. Solvent in PAN solution diffuses out into coagulation bath when PAN solution containing 80-90% of solvent come out through spinneret into coagulation bath with solvent/water mixture. Consequently, PAN solution is solidified, and fibers are formed. Therefore, PAN concentration and solvent diffusion rate should be controlled to obtain proper solid spun fibers. Technical parameters for solvent diffusion rate are solvent ratio in coagulation bath, temperature of solvent/water mixture, and residence time of fibers. In a wet spinning process, washing baths, steam drawing, and winding are followed by extraction of solvent during coagulation. These make wet spinning of PAN solution more complicated. In this study, an effect of wet spinning on tensile properties of PAN based carbon fibers was reported.||-|
