Abstract：
The dispersion of short PA66 fiber in silica sol slurry was studied by means of ultrasonic vibration and mechanical stirring.The kinematic viscosity of silica sol slurry was measured and the influence law of its kinematic viscosity was analyzed.The results showed that short PA66 fiber dispersed well in silica sol slurry by ultrasonic vibration and mechanical stirring.With the change of nylon fiber content from 0%to 0.8%,the kinematic viscosity of silica sol slurry first increases and then decreases,reaching the maximum value of 525 MPa•s when reaching 0.6%,with the increase of short PA66 fiber length,the kinematic viscosity of silica sol slurry increases in a nearly linear manner.
