Abstract
The dynamic and physical properties of neat and glass fiber filled nylon 6 systems were examined. The dynamic viscosity of neat nylon 6 melt was well fitted to:
For the glass fiber filled nylon 6 composite systems, however, a modification of Eq. (1) was required to accommodate the viscosity data. Various types of rheological models are examined to describe the effect of glass fiber on the suspension viscosity, and respective constants of models were determined by a curve fitting. A silane coupling agent had a profound influence on the rheological and physical properties. It increased the dynamic viscosity of composite and yield value, but slightly decreased the activation energy of flow, particularly at high frequency range. Further, it increased the loss factor over the frequency range examined. Plot of storage modulus against loss modulus instead of frequency eliminated the effects of temperature and coupling agent. From the tensile fractured surface of coupling agent treated system, a fibrillar structure was observed.
