The goals of this research work were to evaluate the influence of hybridization of natural cabuya fibers and glass fibers as well as the weight percentage of short cabuya fibers in polyester resin matrix composites, focusing on mechanical properties, such as impact energy. Physical characterization methods, including optical microscopy, were used to analyze the cross sections of the natural fibers and failure zones, as well as FTIR Fourier transform infrared spectroscopy to identify the functional groups of the cabuya fibers. The methodology followed a quantitative and explanatory approach, using different percentages of short cabuya fibers (20%, 25%, and 30%), and varying the hybridization between alternating type and sandwich type. The results revealed that the addition of cabuya fibers in polyester matrix composites, especially in sandwich hybridization, improved impact resistance, obtaining a maximum impact energy of 14.87 J with 30% fibers. This was close to composites with only glass fiber, which obtained a maximum impact energy of 15.82 J with 30% fibers. Greater adhesion was observed between the fibers and the polymer matrix, highlighting the significant role of hybridization in this aspect. Showing a substantial improvement in impact energy compared to alternating hybridization. Which obtained a maximum impact energy of 8.46 J with 30% fibers. This being much higher than the impact energy of composites with only cabuya fiber, 1.82 J with 30% fibers. This research concludes by highlighting the effectiveness of the hybridization of cabuya fibers and sandwich glass fibers as the weight percentage of addition of short cabuya fibers in polyester composites, highlighting its positive influence on crucial mechanical properties.
