Abstract

Ceramic fiber spinning is critical to the manufacture of fibrous monolith ceramics, and understanding the interactions between the polymer matrix and ceramic particle filler is necessary to predict the flow properties of these systems. In this study, poly (methyl methacrylate) (PMMA) was filled with octadecanol-coated St6ber silica, and the rheological behavior of the filled polymers investigated at various filler volume fractions. The rheological behavior of these materials was studied in both dynamic and steady-state experiments. The time required for filled PMMA to reach steady-state behavior under constant shear stress was found to be long, on the order of an hour. The steady-state viscosities increased as expected with filler volume fraction, but did not correlate well with existing models. This is hypothesized to be a result of matrix-filler surface interactions, and will be investigated further in future work.
