In this study mechanochemical devulcanized ground rubber tire powder (GRT) was used to prepare the composites of epoxy by varying the GRT content from 1-12 phr. The structural characterization of the composites was done with FT-IR. Thermal characterization by DSC and TGA was carried out for all the compositions. The increased thermal stability of these composites with increase in GRT content was observed with dynamic thermogravimetry in air. The fractured surfaces of these cured composites were examined by scanning electron microscopy (SEM). These studies reveal good dispersion and interaction of GRT in the epoxy matrix
