Creep behavior of particle filled acrylic composite materials become a major concern when they are used at elevated temperatures. Therefore, for elevated temperature finite element simulations any constitutive modeling requires time— temperature dependent material properties. Unfortunately, this type of data is very difficult to come across in the literature, due to a very long time needed to conduct creep testing. In this study, the creep properties of acrylic casting dispersion PMMA/ ATH were obtained experimentally and the observed characteristics of this material are presented with the experimental data. The underlying deformation mechanisms and the steady-state creep response are also discussed.
