Abstract Scope |
The search for sustainable materials has gained prominence in industry due to the need to reduce carbon emissions and develop materials with suitable properties for diverse applications. Coffee husk, an abundant agro-industrial residue in Brazil, presents potential as reinforcement in polymer composites. This study aimed to develop biocomposites using polystyrene and coffee husk at weight ratios of 60:40, 50:50, 40:60, and 30:70, respectively. The composites were produced by thermopressing at 120 °C for 30 minutes. Mechanical tests (tensile and flexural) showed the best performance for the 40% coffee husk formulation. In addition, the materials were characterized by thermogravimetric analysis (TGA/DTG), Fourier-transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The results indicate that coffee husk can significantly enhance the mechanical behavior of polystyrene composites, while offering an environmentally friendly route for waste valorization. |
