Abstract :The article discusses the increasing interest in natural fibers as a substitute for synthetic fibers in the development of composites due to the depletion of crude oil reserves, environmental concerns and regulations targeting the reduction of carbon emissions. The mechanical properties of natural fibers are closely linked to their chemical composition and structure, which can be influenced by various factors such as harvesting time, growth conditions, storage practices, extraction techniques and pre fabrication chemical treatments. The article also explains the finite element analysis steps for a sandwich structure created using hemp fibers with a 3 mm diameter and 20 mm spacing between two carbon prepreg layers for a 3-point bending test.Finally, numerical analysis outputs of sandwich structures created with hemp fibers at intervals of 10 mm, 20 mm, and 30 mm, and diameters of 2 mm, 3 mm, and 4 mm, are presented graphically to demonstrate the effects of changes in hemp fiber spacing and diameter on stress.
