             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
