The combination of rigid fibers in soft matrix can lead to new materials with outstanding mechanical properties, covering the advantages of both fiber and matrix. The natural fibers are environmental friendly and also solve the issue of polymer degradation to some extent. The properties and geometries of fiber determine its performance within a fiber-reinforced polymeric composite system. Therefore, this work investigated into the effects of fiber aspect ratios on mechanical properties of pineapple leaf fiber (PALF) reinforced unsaturated polyester biocomposites. The diameters of the fibers were measured using scanning electron microscopy. The various fiber lengths used were 5, 10, 15, and 20 mm with fiber diameter of 42.65 μm and weight of 30%. Summarily, the study indicated that fiber aspect ratio significantly influenced the mechanical properties of various PALF-reinforced polymeric biocomposites.
