The fragmentation of liquid sheets produces a collection of droplets. The
size distribution of the droplets has a considerable impact on the coating
efficiency of sprays and the transport of contaminants. Although many processes
commonly used particulate suspensions, the influence of the particles on the
spreading dynamics of the sheet and its subsequent fragmentation has so far
been considered negligible. In this paper, we consider experimentally a
transient suspension sheet that expands radially. We characterize the influence
of the particles on the dynamics of the liquid sheet and the fragmentation
process. We highlight that the presence of particles modifies the thickness and
reduces the stability of the liquid sheet. Our study suggests that particles
can significantly modify the dynamics of liquid films through capillary
effects, even for volume fractions much smaller than the maximum packing.
