Estudo comparativo de diferentes cargas adicionadas ao polipropileno para aplicação na indústria automobilística

Abstract

The automotive market, in search of lighter and more efficient solutions, has increased the use of polymers in the production of parts. Polypropylene, due to its cost-benefit and variety of applications, is a promising choice. The addition of reinforcing fillers such as fiberglass and talc can significantly improve the thermal and mechanical properties of these materials. This work aimed to carry out a comparative analysis of the rheological, mechanical and thermal properties of polypropylene compounds reinforced with glass fibers and talc. Where it was observed how each load affected the properties of the injected parts. The results demonstrated that the glass fiber reinforced material has higher tensile strength, elastic modulus and softening temperature, while talc reinforced compounds have higher elongation, impact resistance and fluidity. These findings have important implications for the application of reinforced polypropylene in the automotive industry, optimizing material performance and efficiency.
