Today, with the increasing use of composites in various industries and the degradability of these materials in the environment, it is of concern to researchers. This has led environmentalists to reduce consumption of conventional synthetic fibers and replace them with biodegradable natural fibers. Of the most used products, are fiber composites widely regarded for their lightness and durability. Among these composites, the use of glass and carbon fibers is common because of their availability and desirable mechanical properties. In the past decades, the use of natural fibers as renewable resources and biodegradable materials in polymer composites has been increasing. These composites are known as green composites. In this study, we tried to use jute fibers with different volume fractions in order to reduce the use of synthetic fibers in common 3D-fabric composites woven with glass fibers. The variables for this type of sandwich structure are the jute yarn positioning in the direction of the yarn and the three-dimensional fabric weave with different volume fraction. This sandwich structure was subjected to 4-point loading test, edgewise compression test and flatwise compressive test. Data analysis of variance showed that there was no difference between the glass-jute hybrid composites and the control sample. Finally, a 4-point bending model was simulated using finite element analysis modeling(abaqus) and it was found that the results of this simulation are in good agreement with the 4-point bending experiment.
