Overview

This investigation highlights the mechanical properties of epoxy composites using spent coffee ground and coffee husks as natural fillers.

Key Points

  • The best mechanical properties were observed with 10 wt.% spent coffee ground, with tensile strength reaching 19.58 MPa.
  • Analysis revealed that coffee husk at 30 wt.% yielded the highest hardness value of 50.33 HRB among tested samples.
  • Microscope analysis indicated strong interactions between the matrix and fillers, affecting overall composite performance.
  • Increasing concentrations of natural fillers showed varying effects on the mechanical properties of the epoxy composite.
