abstract = "In recent years, reinforcements consisting of carbon
nanostructures, such as carbon nanotubes, fullerenes, graphenes,
and carbon nanofibers have received significant attention due
mainly to their chemical inertness and good mechanical, electrical
and thermal properties. Since carbon nanofibers comprise a
continuous reinforcing with high specific surface area, associated
with the fact that they can be obtained at a low cost and in a
large amount, they have shown to be advantageous compared to
traditional carbon nanotubes. The main objective of this work is
the processing of carbon nanofibers, using polyacrylonitrile (PAN)
as a precursor, obtained by the electrospinning process via
polymer solution, with subsequent use for airspace applications as
reinforcement in polymer composites. In this work, firstly PAN
nanofibers were produced by electrospinning with diameters in the
range of (375 +/- 85) nm, using a dimethylformamide solution.
Using a furnace, the PAN nanofiber was converted into carbon
nanofiber. Morphologies and structures of PAN and carbon
nanofibers were investigated by scanning electron microscopy,
Raman Spectroscopy, thermogravimetric analyses and differential
scanning calorimeter. The resulting residual weight after
carbonization was approximately 38% in weight, with a diameters
reduction of 50%, and the same showed a carbon yield of 25%. From
the analysis of the crystalline structure of the carbonized
material, it was found that the material presented a disordered
structure.",
