Resumen: The PMMA/Si acrylic casting dispersion is a composite used to substitute for many indoors household ceramics such as kitchen sinks. In these applications the components are submitted to thermal stresses, originating by severe temperature variations that occur when altemated flows of cold and hot water are applied. Therefore, failure can occur by thermal fatigue, in sorne critica! zones. In this paper it is presented a part of this study conceming a numerical analysis of the thermal stresses in two composites with different volume fraction of filler and particle size, which trade mark are Asterite and Ultra-quartz. The influence of the cold and hot water temperatures as well as the time of interruption of water flow in the transition between hot and cold water were performed using the Cosmos/M finite element method software. The thermal stress results, together with the results of fatigue and fracture tests, were used to predict thermal fatigue tolerance of defects in products manufactured with these composites.
