The present study is on the production and characterization of untreated and treated Urena lobata (U. lobata) fiberreinforced polypropylene (PP) composites. The untreated and treated U. lobata/PP composites were produced bycompression moulding at varying weight percents of the fibers (5, 10, 15, 20 25, 30, 35) wt%. The followingcharacterizations were carried out on the treated and untreated U. lobata/PP composites; X-ray diffraction (XRD), FourierTransform Infra-red spectroscopy (FTIR), and Scanning electron microscopy (SEM). Due to enhanced fiber-matrix adhesion,attributed to increased fiber roughness and crystallinity, the alkaline treated U. lobata composites showed enhancedmechanical, structural and morphological properties over the untreated U. lobata reinforced composites. Furthermore, the30 wt% fiber loading, gave the best combination of the mechanical properties, as improvement in tensile strength (2-22 %),percentage elongation (5-26 %), and impact strength (2-19 %) was observed for the treated fiber reinforced compositecompositions. Consequently, the 30 wt.% Urena lobata/PP composite is recommended for the development of PMC basedautomobile components.
