The rheology of colloidal suspensions depends on many physical variables including particle shape. Our goal is to develop an understanding of how particle shape affects suspension rheology for both dilute and concentrated suspensions. A model system of cubic aluminosilicate zeolyte particles (PQ corporation) is suspended in glycerol and characterized by light scattering, SEM, and dilution viscometry. Stable suspensions are prepared up to a concentration of 55%wt and characterized by rheology. In the highly concentrated regime, the suspensions exhibit both shear thinning and shear thickening. Comparison to suspensions of spherical particles of comparable size show the cubic particle suspensions show less shear thinning at low shear rates, behaving similarly to suspensions of rod-like and clay-like particles (Egres, JOR 2005). The onset of shear thickening is studied as a function of the particle concentration. Various measures of the effective volume fraction are explored to compare the shear rheology of these suspensions to those of spherical particle dispersions. Because the higher concentration dispersions exhibit significant shear thickening, concentrated suspensions are intercalated into ballistic fabrics to explore their efficacy as stab and ballistic protective materials. The results are compared to previous work on fabrics intercalated using spherical and clay-like particle dispersions (Decker, Comp. Sci. Tech. 2007).
