Now-a-days, the solid wastes are used in many areas of manufacturing. But the utilization of these wastes in polymer composites has rarely been seen. Therefore, exploring new avenues for its application would be an exciting task as far as the materials recycle aspect is concerned. This article presents the fabrication and investigation of physical and mechanical properties of glass fiber reinforced epoxy composites with red brick dust (RBD). RBD is the waste or leftover powder, or the powder formed from deformed bricks in the process of their manufacturing. Bricks can be deformed while handling and the deformed bricks cannot be used for construction purposes; hence, they are dumped as waste. Hand lay-up technique is used for composite fabrication. RBD is varied from 0 to 30% by weight and physical and mechanical tests are performed on the composite samples. X-ray diffractography (XRD) is carried out in order to identify the phases present in raw RBD. This work shows that density, void content, hardness and impact strength of the composites increases with the increase in red brick dust content while the decrease in tensile and flexural properties are observed.
