This work deals with the processing and abrasive tests in epoxy - Silica composites, and the evaluation of the possibility of their technological application in dimension stones polishing crowns - commonly made of magnesian mortar (named SOREL) - SiC.. In this sense the composites were processed at the compositions epoxy - (70-75-80-85-90) weight % SiO2, by mixing and curing. The composites were submitted to wear tests, simulating a dimension stone polishing operation. Comparing the results obtained from the processed composites with those from the SOREL-SiC - commercial crowns, it was observed the technical feasibility of using the polyester-SiC composite in the dimension stone industry.
