| Abstract | ||||
| This study investigates the effect of micro-glass fillers on the mechanical and thermal properties of natural rubber (NR) composites. Micro-glass particles, derived from recycled glass bottles, were incorporated into the NR matrix at varying concentrations (0%, 10%, 20%, 30%, 40%, and 50%). The composites were prepared using a two-roll mill and vulcanized under controlled conditions. Mechanical properties, including tensile strength, elongation at break, and hardness, were evaluated, along with thermal stability using thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The results indicate that micro-glass fillers significantly enhance the mechanical properties of NR, with optimal performance observed at 30% filler content. At this concentration, the composite exhibited an elasticity modulus of ~ 54 MPa and tensile strength increased from 4.6 MPa (pure NR) to 8.7 MPa at 30% micro-glass. However, higher concentrations led to reduced ductility and potential agglomeration. Thermal analysis revealed improved heat resistance with increasing filler content, making these composites suitable for applications requiring enhanced mechanical and thermal performance. | ||||
