Natural fibers derived from plants are gaining attraction for its low-cost production, excellent mechanical properties, eco-friendly nature and availability. They act as an effective replacement of synthetic materials, makes them suitable for industrial applications. In this work, natural fiber derived from the Pineapple leaf fiber (PLF) and powder derived from  Prosopis Juliflora  (PJP) plant as the filler was utilized as an effective reinforcement for polymer matrix composites. PLF has high cellulose content, makes it suitable for the achievement of high tensile strength, whereas the porous nature of the fiber surface enhances bonding with the polymer matrix. The low cost and wide availability of the fibers make it a suitable alternative for the harmful synthetic fibers. Semi-crystallinity of the fiber allows reduction in water absorption. The PJF belonged to gelatinous or mucilaginous type. PLF was chemically treated with NaOH to remove the wax content on the surface and to improve its mechanical properties. Composites were fabricated by using compression molding machine with 30 weight percentage (wt.%) of untreated PLF and PJP, 30 wt.% of treated PLF and PJP, 40 wt.% of treated PLF and PJP, 50 wt.% of treated PLF and PJP. The remaining wt.% attributes to the epoxy matrix addition. In the fiber wt.%, equal weights of PLF &amp; PJP were taken. The untreated and treated fiber composite samples are tested for their tensile, impact and flexural strength. SEM images of the PLF, PJP and mechanical tested samples were analyzed. Water absorptivity test was carried out to identify the absorption level of fibers in the composite. The test results suggest that the Pineapple leaf fiber and  Prosopis Julifora  powder reinforced epoxy reinforced composites would be a low-weight, low cost and higher strength material appropriate for industrial applications.
