FABRICATION OF CARBON FIBERS FROM COMMERCIAL WET SPIN POLYACRYLONITRILE FIBERS
Carbon fibers are fabricated from different materials such as special polyacrylonitrile (PAN) fibers, cellulose fibers and pitch. But PAN fibers are recognized as the most widely used precursor for the present-day manufacture of carbon fibers. The process of fabrication carbon fibers from special PAN fibers is composed of two steps including oxidative stabilization at low temperature and carbon...
متن کاملMultiwall Carbon Nanotube Reinforcement of Polyacrylonitrile Fibers
Aligning multiwall carbon nanotubes (MWNTs) with the direction of load is desirable for maximizing tensile reinforcement in composites. This has been accomplished by spinning composite fibers containing MWNTs[1]. The shear and elongational flow fields inherent to fiber processing cause the MWNTs to align with the fiber axis. Efficient stress transfer from the matrix to the MWNTs is also a cruci...
متن کاملDrawing dependent structures, mechanical properties and cyclization behaviors of polyacrylonitrile and polyacrylonitrile/carbon nanotube composite fibers prepared by plasticized spinning.
Drawing to change the structural properties and cyclization behaviors of the polyacrylonitrile (PAN) chains in crystalline and amorphous regions is carried out on PAN and PAN/carbon nanotube (CNT) composite fibers. Various characterization methods including Fourier transform infrared spectroscopy, differential scanning calorimetry, X-ray diffraction and thermal gravimetric analysis are used to ...

متن کاملFlexural Behavior of Cementitious Composites Reinforced by Synthetic Fibers
The application of fibers to reinforce cementitious materials is a well-known subject. At first, asbestos fibers are used in industrial process to produce fiber reinforced cement sheets. Thereafter, various types of synthetic fibers are produced and used as asbestos substitutes. The aim of the present work is to evaluate the effect of synthetic fibers on the flexural behavior of cementitious co...
