The first work on the rheology of
anisometric particle suspensions (Jeffery, 1922) concerns ellipsoids.
The presence of highly oriented
anisometric particles combined with the orientation of either the amorphous or crystalline phase imposes considerable undesirable anisotropy in in-plane shrinkages, which, in many cases, can lead to warpage and part deflection.
Most
anisometric particles were detected in the blend compatibilized with SB1.
Considering the previous findings [5], [29], the stress overshoot could be attributed to network structure break down and the transient hydrodynamic stress induced by rotational motion and alignment of
anisometric particles.
The shear stress overshoot and the scaling of stress with strain have also been reported for suspensions with
anisometric particles and polymer liquid crystals (29), (30).
