Abstract:
The growing impacts of climate change, combined with the high demand for environmentally responsible practices, have encouraged the scientific community and the industrial sector to seek sustainable alternatives for the development of new materials [1]. In this context, natural fiber-reinforced composite materials have emerged as a promising alternative to synthetic composites, not only due to their lower environmental impact but also because they offer economic and functional advantages in various applications [2]. The Amazônica region, rich in plant biodiversity, holds significant potential for the use of fibers extracted from native species in the development of sustainable composites. This contributes to reducing dependence on synthetic materials while also promoting the appreciation of the forest’s natural resources through responsible extractive practices [3]. The incorporation of these natural fibers into materials—especially in the construction sector—represents a significant step forward in the development of sustainable cities, while also promoting the growth of the regional bioeconomy, technological innovation, and local infrastructure [4]. In this study, polyester matrix composite materials reinforced with guaruman fibers were analyzed for their flexural mechanical properties. Test specimens were produced using silicone molds and sanded to meet the specifications of ASTM D790 for flexural strength testing. Specimens were fabricated with 10%, 20%, and 30% guaruman fiber volume fractions in polyester resin. The results were validated through ANOVA statistical variance analysis. The flexural mechanical results indicated a slight increase in the average strength. Regarding the flexural modulus, there was an increase in material stiffness as the fiber content increased. ANOVA indicated no statistically significant differences in the strength results among the composites. Although no significant differences in strength were observed, it is important to highlight the reduction in resin content required to produce composites with 30% fiber volume, without compromising strength.
