As evidenced by Raman spectra, stretching during melt spinning promoted the interfacial tt-tt stacking interaction effectively and realized the interfacial enhancement in composites., finally resulting in a great improvements of mechanical properties of fibers. The additives were also shown to restrain the ability of polyamide 6 for crystallization. The highly oriented skin thickness is the most important factor in determining the tensile properties of the sample. dtnqF5ZkOtrGxhY0Hc107jqxodqB8vyBS9ZYzE/nLrKnNL9XWOsDbydplrd/tEx4BLqpPiyS97H7 A notable increase of the d.c. electrical conductivity in 7 orders of magnitude is observed for the CFT-metal laminates with respect to the neat PA6. Because of the chemical similarity of the composite components, good bonding at the fiber-matrix interface could be expected. Polyamides (PAs) are one of the most important engineering polymers; however, the difficulty in dissolving them hinders their applications.
