The mechanical properties of epoxy composites filled with non‐functionalized oxide nanoparticles is influenced by a number of factors. The development of sophisticated materials also necessitates a direct relationship between a material and its qualities from an industrial standpoint. This work describes the fabrication and testing of marble dust nanoparticle reinforced epoxy structural adhesive composites. The behaviour of composite structure after reinforcing with marble dust has been highlighted in this study. The marble dust in different wt.% (i.e., 0, 1.5, 3 and 4.5 wt.%) is incorporated into LY 556 epoxy and composites fabricated via casting method. The primary focus of this study was to evaluate the effects produced on the physical, mechanical and tribological properties with varying filler (marble dust) content. The results indicated significant improvement in hardness and wear resistance of the composite, whereas tensile strength and flexural strength show decrement behaviour with increase in marble dust content. Tribological behaviour of adhesive composites was examined by assessing the wear tracks via FE‐SEM. Results indicated presence of debris particles and mild abrasion caused by the hard marble dust particles in the matrix and could also be seen in SEM micrographs. Finally, TOPSIS is implemented to identify the best alterative from the developed epoxy adhesives based on physical, mechanical, thermal and tribological properties.
