The fiber degradation in the kneading disk region of co-rotating twin screw extruder was studied, with a closed single stage mixer of co-rotating twin screw extruder as a model for the analysis.
In the previous paper, we explained that the stress in the kneading zone was proportional to the screw torque. In this experiment, we measured the fiber length distribution and the average fiber length, under various compounding conditions.
Consequently, it was found that the fiber length distribution was determined by the shear stress and the total number of rotations, and if the average fiber length was equal, the fiber length distribution was also equal.
Key words: Co-rotating intermeshing twin screw extruder / Kneading disk / Fiber length distribution / Shear stress / Total rotation
