Thermoplastic PVC matrix was reinforced with waste fiber portion of Citrus Maxima (CM) fruit for making composites. The CM fibers were separated, dried at 50-60 °C for 24 h, coarse ground and sieved. PVC/CM fiber composite film with different fiber loading (10-70 wt%) were cast using solvent casting method. Sheets were cast in large petri dish using tetrahydrofuran (THF) as solvent and dried in an oven thoroughly at 50-60 °C. The evaluation of mechanical properties was done as per ASTM D882; stereo image of the fractured specimen and FTIR was used for the study of morphology and microstructure of the composite. Incorporation of fibers into PVC made the material stiff, leading to significant increase in Tensile Modulus, Breaking Strength and Yield Stress at higher filler loadings. Uniform distribution of the fibers in the microstructure of PVC matrix led to the formation of cross-ply structure and improved the mechanical properties. These results indicate that the fiber portion from CM can be effectively used as an eco-friendly reinforcing additive to form PVC composites.
