Compósitos híbridos reforçados por fibras de juta e vidro: uma revisão de estudos recentes

Abstract

The study and development of materials are essential to correctly and safely meet the most diverse applications that society demands. Currently, there is a great interest on the part of the academic and industrial sector for the creation of materials that meet the necessary properties associated with minimal damage to the environment and human beings. In this scenario, the aim is to replace composites reinforced with synthetic fibers with hybrid composites reinforced with synthetic and natural fibers, being verified in several situations as an excellent change since the hybrid reinforcement can meet the applications’ requirements for environmental preservation interests. The present work organizes several studies about hybrid composites reinforced by jute and glass fibers in chronological order, modifying several parameters, such as, for example, the resin, the sequence of the layers, the properties evaluated, the manufacturing processes, among others. The results of the tests of traction, bending, impact, hardness and compression are synthesized in order to verify the possible improvements in the mechanical properties resulting from the hybridization process of natural and synthetic fibers. Furthermore, changes in morphological, thermal, dynamic and tribological properties are presented. By gathering this information, it's concluded that the hybridization of glass and jute fibers for reinforcement of composites with different matrices presents itself as an excellent means to satisfy economic and environmental parameters, in addition to the necessary properties for different applications.
