Sustainable bio-based PET hybrid composites reinforced with organic waste and basalt fibres with antibacterial addition.

ABSTRACT: This study presents the development and characterization of novel hybrid composites based on a bio-based polyethylene terephthalate (bioPET) matrix reinforced with natural and waste-derived fillers-mollusc and eggshell particles, basalt fibres, and titanium dioxide (TiO₂). The composite specimens were produced using the injection moulding technique. The incorporation of these eco-friendly additives aims to enhance the mechanical performance, sustainability, and functionality of the composites. Mechanical tests including tensile, bending, Charpy impact, and low-cycle fatigue experiments were conducted. The addition of basalt fibres significantly improved tensile and flexural moduli, as well as impact resistance. Organic fillers contributed to increased stiffness but often led to brittleness
