Dataset on mechanical properties of natural fiber reinforced polyester composites for engineering applications

This dataset comprises the mechanical properties of sisal, sorghum bicolor and coconut coir reinforced polyester composites. The mechanical dataset illustrates the tensile, flexural, impact and hardness strength of natural fiber composites by varying the weight percentages from 5 to 25 wt.% of sorghum bicolor and coconut coir. The composites samples were fabricated by hand layup process. The mechanical properties were determined from in-plane tensile, flexural, impact and hardness of the natural composites. The dataset here helps the readers to understand the important properties of the natural fibres reinforced polyester composites. However, it is revealed that the addition of sisal and coconut coir fiber can enhance the properties.
