The goal of current research is to replace synthetic materials with natural, biodegradable, and renewable ones. A lot of study is being done on natural fiber composites because of its unique properties and environmental friendliness. Natural fibers are advantageous since they are easily accessible, manageable, and biodegradable. The goal of the current study is to evaluate the changes in the mechanical properties of polypropylene reinforced with chopped pineapple leaf and okra fiber. Additionally, the influence of the fiber's ratio, content, and chemical processing on its mechanical properties was examined. There are numerous sources of fiber in Bangladesh, including the fiber in okra and pineapple leaves. Chemically, okra fiber and pineapple leaf were both treated with 5% sodium hydroxide. Random and discontinuous pineapple leaf and okra fiber reinforced hybrid polypropylene composites were produced using compression molding. The ratio of okra fibers to pineapple leaf fibers ranged from 4:1 to 1:1 to 1:4. The percentages of fiber loading were 5, 10, 15, and 20%. The best set of mechanical properties were attained when polypropylene was reinforced with 5 wt% pineapple leaf and okra fiber at a ratio of 4:1. On the other hand, fiber reinforced composites that had been treated with sodium hydroxide treatment outperformed untreated composites in terms of their mechanical properties.
