Abstract: This study deals with the brass debris which is obtained through matte smelting and refining of brass or different machining process like grinding operation, to use as filler in epoxy-resin composites. The common uses options for brass debris are recycling, and production of value-added waste products. In this study random mixing processes to prepare (Epoxy / brass) composites done by using brass debris of three different grades with different grain size (600, 800 and 1180) μm as reinforcement in epoxy resin with different weight percentages (2%, 4%, 6% and 8%) respectively. Using tensile and impact test to evaluate the mechanical properties of the prepared composites. Results show that with coarse grain size of brass debris added to epoxy resin, it is very important to decrease the amount of weight percentage added to it, so as to improve the tensile or impact properties of (Epoxy / Brass debris) composites. On the other hand a very low weight percentage (2%, 4%, 6%, 8%) of metal brass debris which there is no significant improvement in toughness, noticed that can significantly reduce the impact absorbed energy (impact toughness) of the composite samples. The best value of the toughness can be obtained with the epoxy-BD600 and weight percent of 8%. This research includes processing procedure, and study of the mechanical behavior of grades of such brass debris filled epoxy-resin composites. This paper concluded that the possibility of utilize of brass debris as secondary filler element for the preparation of composite materials and producing the bras debris such as added-value products.
