This analysis reveals the mechanical properties of epoxy composites with wood dust and crumb rubber fillers, suggesting optimal fractions for enhanced performance.
Key Points
The composite with 5% crumb rubber achieved the highest tensile strength of 15.52 MPa.
Flexural strength peaked at 30.46 MPa with 10% crumb rubber in the composite blend.
Hardness was maximized at 75.9 HRC with 15% wood dust, indicating varying performance across filler types.
Fracture surface analysis showed wood dust agglomeration lowered mechanical performance, stressing the need for optimal filler selection.
