“…To this day a lot of polymers have been successfully electrospun and the resulting nanofibers were employed as reinforcements in different polymeric matrices. 10,[15][16][17][18][19][20][21][22][23][24][25][26][27] According to these studies, the properties of the polymer matrices can be improved by incorporation of electrospun polymer nanofibers. In general, the most common reason for using nanofibers in polymer matrices is not to enhance the mechanical properties of the polymer matrix, but to improve optical, electrical, and chemical properties.…”

“…23,24 There are also cases that indicate the use of nanofibers with the aim of improvement or preservation of the flexibility and toughness of the polymer matrices. [25][26][27] In our previous research, 27 we employed a hot press method to fabricate composites with PE as the matrix and electrospun PA6 nanofibrous mats as reinforcement. The melt processing method was selected due to its eco-friendliness and easy processability, being the potential method for the large-scale production of polymer composites.…”

The importance of polymer-polymer thermoplastic composites is increasing due to ease of recycling. This work investigates the effects of remolding temperature and thermal annealing on the properties of polyethylene (PE) composites containing PA6 and GO/PA6 electrospun nanofibers. Nanocomposite samples were prepared by sandwiching several layers of PA6 or GO/PA6 electrospun mats and PE films in a hot press and subsequently were remolded at varying higher temperatures in a range of 180 to 210°C. Furthermore the remolded samples at 200°C were then annealed at 100°C for 10 h. SEM and DMTA results of the developed samples showed that the application of higher remolding temperatures, close to the melting point of PA6, improves wettability and interfacial strength in the composites. The DSC results of the samples revealed a slight increase in PE crystallinity due to the induced crystallization on the surface of nanofiber mat. It was also observed that an increase in the remolding temperature increases the tensile properties of the composites with the best properties obtained at a remolding temperature of 200°C. Increasing the remolding temperature beyond 200°C decreases the tensile properties of the composites due to melting and geometry degradation of the nanofibers. The results revealed that the annealing of the samples at 100°C for 10 h increases the degree of crystallinity and tensile properties. The highest yield strength, 16.4 MPa, and modulus, 277 MPa, were obtained for the composite containing 10.5 wt% of pure PA6 nanofibers. The elongation and toughness of this composite compared to those of pure matrix were increased by 61% and 83%, respectively. In the remolded and annealed nanocomposites, a crystalline region, as thick as 20 microns, grown on the surface of the nanofiber mat or nanofiber rich region, so called transcrystalline region, was observed by polarized reflected light microscopy.

“…4 After that, the high performance carbon fiber reinforced polymeric composites have been fabricated for various technical industries like aerospace, automotive, and construction industries. [5][6][7] The carbon fibers may form weak interfacial adhesion with the matrix. 8 Consequently, the carbon fibers may have poor wettability and interactions with the polymers.…”

The carbon fibers have been employed to form the high performance composites. The use and compatibility of carbon fibers have gained research interest. Incidentally, the nanocarbon nanostructures such as carbon nanotube, graphene, nanodiamond, and fullerene have been deposited on the carbon fiber surface to increase the interfacial linking with the matrices. Various physical and chemical methods have been used to deposit the nanocarbon on the carbon fiber surface including the chemical vapor deposition, electrospraying, electrophoretic deposition, etc. This review basically highpoints the prospective of the formation of the polymer/fiber composite and polymer/fiber/nanofiller nanocomposite for the advanced structures. The effect of the addition of the nanocarbon on the properties of the polymer/carbon fiber materials have been observed. Specifically, the morphology, strength, toughness, storage modulus, thermal stability, and other physical characteristics have been observed. Moreover, the interfacial adhesion and resulting interfacial features of the polymer/fiber/nanofiller nanocomposite have also been perceived.
