Cassin, I. Appelqvist, N. Bossu, I. T. Norton]  In this article, experimental evidence for the influence that steric interaction and orientational coupling have on the orientation of cellulose fibre dispersed in a particulate matrix is given. The filler coefficient of the fibre suspension is used as a probe to follow the average fibre orientation. It is shown that the fibres do not order into a nematic phase after numerous shear stress steps. From the evolution of the filler coefficient as a function of the time the stress was applied, a rate constant for reorientation was determined. Even in the dilute regime, its value depends on the fibre volume fraction. Results obtained with various fibre and particle sizes have been scaled onto a master curve, where it is shown that the rate of reorientation increases with the fibre-particle size ratio.
