A carbon nanostructure CNS composed of highly branched and entangled carbon nanotubes CNTs is grown on a fiber surface and used as a carbon-enhanced reinforcement CER in a nylon matrix. A majority of the masterbatch CER material research is focused on electromagnetic shielding applications however, the CER system, with the CNT network fixed to the host fiber, provides a novel approach of minimizing CNT agglomeration. Tensile specimens are injection molded with varying weight percentages of CER to evaluate effect of the reinforcement on the mechanical properties. Tension testing showed that the introduction of CNS increased the modulus and yield strength of the nanocomposite but reduced its fracture toughness.
