本研究的主要目的是研究纤维悬浮液在牛顿流体和聚合物溶液中的黏性、弹性和毛细流动特性。所用的填充物是玻璃、碳、尼龙和维尼纶纤维。以甘油为牛顿悬浮介质，HEC和Separan溶液为粘弹性悬浮介质。用同轴圆柱旋转粘度计和平行板流变仪分别测量了粘度和一阶法向应力差。研究了纤维浓度、长径比、纤维直径和纤维柔韧性对纤维悬浮液黏性和弹性的影响。得到了甘油中纤维悬浮液的相对粘度和第一法向应力差的经验方程。第二部分讨论了这些悬浮液的毛细管流动。
The main purpose of this study was to examine the viscous and elastic properties and capillary flow of fiber suspensions in Newtonian fluids as well as in polymer solutions. The fillers used were glass, carbon, nylon and vinylon fibers. Glycerin was used as a Newtonian suspending medium and HEC and Separan solutions as viscoelastic suspending media. The viscosity and the first normal-stress difference were measured using a coaxial cylindrical rotating viscometer and a parallel-plate rheogoniometer respectively. The influence of the concentration, aspect ratio, diameter and flexibility of the fibers on the viscous and elastic properties of the fiber suspensions was investigated. Empirical equations were obtained for the relative viscosity and first normal-stress difference for the fiber suspensions in glycerin. The capillary flow of these suspensions is discussed in part II.
