Abstract
::
Fiber reinforced polymer (FRP) composites are considered to be potential alternatives to the many conventional materials in structural applications due to their superior properties such as high specific strength, high resistance to corrosion, lightweight, and ease of tailorability. While FRP composites have proven superior in-plane properties, considerable doubt in the out-of-plane properties is still present. Incorporation of nanofillers like carbon nanotubes (CNTs) and carbon nanofibers (CNF) into a polymer matrix is a very attractive way to combine the mechanical and electrical properties of individual nanofillers with the advantages of polymer. The superior properties of these nanofillers offer exciting opportunities for new nanocomposites, but the important limitation for some potential applications of CNTs/CNFs come from the fact that difficulties in dispersion, formation of weak physical bonds with the matrix, low wettability with most of the polymers and due to their random orientation in the polymer matrices have exhibited substantially lower mechanical and thermal properties than expected. With optimization of process parameters and use of functionalized CNTs was observed to produce better properties than the pristine CNTs. Furthermore, successful alignment of CNFs in vinyl ester (VE) polymer was achieved using electrical current. Alignment of CNFs surpassed random CNFs in terms of tensile strength and showed ~29% increment, as more number of CNFs were loaded along there length.
