Abstract

The thermal behavior of vinyl ester (VE) resin matrix composites filled with mechanochemical devulcanized ground rubber tire powder (GRT) was studied with thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). Decreased thermal stability of composites was observed with increase in concentration of GRT.  The flexural properties such as the flexural strength and flexural modulus of these composites were evaluated by varying the GRT content from 1-12 wt%. Continuous increase in modulus was observed while flexural strength decreases with increase in GRT concentration.
