Ismail, Ahmad Fauzi and Rahman, M. A. and Mustafa, A. and Ng, B. C. and Hasbullah, Hasrinah and Rahaman, M. S. A. and Abdullah, M. S. (2006) Effects of residence time on the characteristics of PAN-based fibers and its fabrication through solvent-free coagulation process. In: 2nd National Carbon Fiber Conference 2006, 6th-9th June 2006, The City Bayview Hotel, Langkawi.
The paper reports the fabrication and characterizations of PAN fibers fabricated using residence time in the range of 2 â€“ 5 s in the solvent free coagulation process. The PAN fibers were characterized using SEM, FTIR-ATR and tensile testing machine. The SEM photographs revealed that the cross-section of PAN fiber, for all sample was free from large void. A residence time of 3 s was found to be the most suitable residence time for fabricating the PAN fibers in the solvent-free coagulation bath. FTIR-ATR data suggested that the PAN fibers possess better molecular orientation and exhibited the highest Young's modulus of 2.55 GPa.
