Abstract
The time and shear rate dependent extrudate swell behavior of a blow molding grade Nylon 6 incorporated with glass fibers was investigated under isothermal conditions where gravity effects were absent. The extrudate reached its equilibrium swell value immediately upon exit from the capillary and the swell behavior was not significantly affected by the shear rate in the capillary. Microstructural analysis revealed the presence of a skin layer with a high degree of fiber orientation in the flow direction and a matrix-rich core zone with a lower than expected fiber packing density.
