Compósitos poliméricos com utilização de pó de serra como agente de reforço

Abstract

The increasing demand for high-performance materials with low environmental impact has driven the use of natural fillers in polymers. In addition to providing lightness and strength, these fillers are ecological alternatives compared to synthetic fibers. Sawdust as a reinforcement filler in polypropylene enables the creation of composites with greater stiffness and tensile strength, which can meet the needs of industries such as construction, automotive, and electronics. This study aims to analyze the mechanical properties of polypropylene composites reinforced with sawdust, a byproduct of the wood industry with potential for sustainable reuse. To evaluate the influence of different wood powder concentrations on the composite's strength and elasticity, tensile tests will be conducted, allowing an assessment of its feasibility for industrial applications requiring durable and sustainable materials. Furthermore, by proposing alternatives for sawdust utilization, this study seeks to reduce the waste of this residue, which often faces logistical and financial challenges for transportation and storage. Thus, this research aims to contribute to the development of materials with lower environmental impact, promoting a more sustainable approach and exploring the advantages of composites reinforced with plant-based fillers.
