Utilization of industrial waste is an important aspect in order to reduce the cost of disposal, environmental pollution, usage of natural resources and cost of production. In the present study, it is aimed to make use of various industrial wastes like Coal Dust (CD), Cement By Pass Dust (CBPD), Coal Fly Ash (CFA), Marble Powder (MP), mixture of Coal Dust and Coal Fly Ash (CDCFA), mixture of Coal Dust and Cement By Pass Dust (CDCBPD) and mixture of Coal Dust and Marble powder (CDMP) in the compositions of 0 wt%, 2.5 wt%, 5 wt%, 7.5 wt%, and 10 wt% along with E- Glass fiber at 50 wt% and Epoxy resin in proportion with the industrial wastes to prepare the hybrid composites slabs or laminates of size 300X300 mm2. These slabs are cut into specimens for mechanical characterization as per ATM standards. The Mechanical Characteristics like Tensile Strength, Flexural Strength, Interlaminar Shear Strength, Impact Strength and Hardness were determined. From the results it is observed that the composites filled with CDCFA at 10 wt% has exhibited the maximum Impact Strength of 2098 J/m and Hardness of 61H. The maximum Tensile strength is obtained for the composite filled with CDCFA at 2.5 wt%. The maximum flexural strength and Interlaminar Shear Strength of 857.22 MPa and 35.86 MPa respectively were observed in the composites filled with CDCBPD at 10 wt%. This study of mechanical characterization shows that addition of industrial wastes can enhance the mechanical properties compared to the composites prepared without fillers. The use of these industrial wastes in the large scales to prepare the composites can reduce the fabrication cost as well environmental pollution and disposal problems.
