Özet

Linear viscoelastic properties of a model suspension containing hydroxyl terminated polybutadiene (HTPB) and glass beads with filler concentration up to 30% by volume were investigated by using a Haake parallel disk rheometer. For all the suspensions, it was observed that the rheological properties such as the storage modulus, G', loss modulus, G" and complex viscosity, eta* increases with the filler content, Phi. The relaxation spectra was calculated by using G' and G". The relaxation moduli, G(i)(lambda(i),Phi), decreased with the relaxation time, lambda(i) but increased with the filler content, Phi.
