In recent years, there has been an increasing environmental consciousness and awareness of the need for sustainable development, which has raised interest in using natural fibers as reinforcements in polymer composites to replace synthetic fibers such as glass. Natural hybrid fiber, which consist of two relatively thin and stiff faces bonded to a low density core, offer many benefits such as high bending stiffness, good thermal and acoustic insulation properties, and high specific energy absorption. In this study, natural hybrid reinforced composites panels are made with Hemp fabric/glass fabric/Epoxy and Hemp fabric/carbon fabric/Epoxy 3mm thickness and composites are fabricated using Simple hand layup technique. Appropriate test methods as per standards and guidelines are followed to analyze mechanical behaviour of the composites. The physical and mechanical characteristics of the natural hybrid reinforced composites used for the fabrication of the sandwich panels are tested as per the ASTM standards. To characterize the tensile, compression and flexural properties of the natural composites, a series of tensile test, compression test and 3-point bending tests were conducted on the sandwich panels. A quantitative relationship between the Hemp fabric/glass fabric/Epoxy and Hemp fabric/carbon fabric/Epoxy has been established with varying thickness.
