Description

This study examined the effects of the epoxidized castor oil (ECO) and Al2O3 content on the thermal stability and fracture toughness of the diglycidylether of bisphenol-A (DGEBA)/ECO/Al2O3 ternary composites using a range of techniques. The thermal stability of the composites was decreased by the addition of ECO and Al2O3 nanoparticles. The fracture toughness of the composites was improved significantly by the addition of ECO and Al2O3 nanoparticles. The composite containing 3 wt % Al2O3 nanoparticles showed the maximum flexural strength. Scanning electron microscopy (SEM) revealed tortuous cracks in the DGEBA/ECO/Al2O3 composites, which prevented deformation and crack propagation
