Abstract
Composites of chopped carbon fibers (CCF) or carbon nanotubes (CNT) with nylon 66 were prepared by melt-mixing followed by extrusion/drawing of filaments. The combined effect of composition and flow on morphology and crystalline orientation was studied by microbeam synchrotron x-ray diffraction. The highest degree of orientation was observed in filaments of CNT-nylon 66 at the highest draw ratio. Mechanical tensile testing showed that for 1wt.% of CCF or CNT the modulus of the composite filaments was improved by 15% and 30%, respectively, compared with neat nylon 66. The results indicate that the alignment of CNT-crystalline domains in the flow direction generate a strong reinforcing effect.
