Randomized trial studied mechanical properties of biocomposites with coffee grounds, suggesting optimal processing for stronger materials.

The study aims to assess how mechanical and thermal fields impact the properties of biocomposite materials filled with coffee grounds.
Heat treatment of biocomposite compositions containing 190-200 wt. parts of coffee grounds at 150°C under 8-11 MPa pressure.
Evaluation of compressive strength and impact toughness of the materials using established testing methods.
Infrared spectroscopy analysis to investigate the structuring of the biocomposite materials.
Compressive strength of 200 wt. parts coffee ground biocomposite reached 75.8 MPa with a density of 1.17 g/cm3.
Dynamic load resistance improved by using 190 wt. parts of filler with a preliminary pressing of 8 MPa.
Optimal thermo-mechanical processing identified with maximum exposure of 2 hours in a thermal field.
