Effect of High-Shear Mixing on Alignment of Carbon Nanofiber/Epoxy Nanocomposites
Abstract: AbstractOne of the major technological issues limiting widespread use of epoxy polymer nanocomposites containing carbon nanofibers is processability, where the dispersion or alignment of the nanofibers is crucial to performance of the composite. Poor dispersion of the nanofibers can lead to deterioration in properties, while aligning them affords the opportunity to maximize properties in a given direction. The authors have recently investigated the effect of high-shear mixing as a potential …
