Quasi-carbon fibers and the composites

The aim of this report is to study the properties of quasi-carbon fibers (Q CF) prepared from the PAN fiber precursor by pyrolysis at a temperature bet ween 400 degrees C and 1200 degrees C. The resistivity of QCF with differen t heat-treated temperature (HTT) was investigated by a Hall-35 testing syst em, and the flexural properties of the result composites (QCFC) are also di scussed. In addition, the scanning electronic microscope (SEM) was utilized to observe the surface morphology of QCF and the fracture section of QCFC obtained from flexural testing.
