Abstract
The study of interlaminar shear in flexion of hybrid composites of sisal (Agave sisalana) and cana-brava (Gynerium sagittatum) were performed experimentally through the short beam test. The objective was to study the incorporation of finely chopped cana-brava fibers as an intermediary element to ensure greater interfacial mechanical coupling between sisal mats and polyester matrix, thus increasing stiffness and shear strength. The results haves shown good mechanical properties for hybrid composites in compared to sisal mats, expressed by the increasing on 12% of short beam resistance. The combination of sisal and can represent technical and environmental relevant parameters on composite materials, since they are natural resources with greater potential of exploitation and reutilization, especially in the most vulnerable regions in the state of Bahia.
