The hybridization effect of sisal/cotton interwoven fabric backed by paper roving with jute woven material isinvestigated in the presence of polylactide (PLA) matrix. The biocomposites (five) were produced through varying different(100/0, 75/25, 50/50, 25/75, and 0/100) proportions of sisal/cotton with jute woven fabrics respectively in the laminates. Afterthe successful reinforcements, mechanical properties were investigated in terms of tensile and flexural tests. Moreover, thewater absorption, thickness swelling, and moisture content tests were also examined for assessing the physical anddimensional stability of developed hybrid composites. The water absorption and thickness swelling tests were carried out inthe presence of water after 2 h and 24 h immersion. The highest mechanical properties were found in case of 100 % sisal/cotton reinforced composites whereas the lowest value was observed in case of 100 % jute fiber. The morphological views ofthe developed materials were also characterized using SEM (Scanning electron microscopy) to observe the surfaces beforeand after the tensile load. The SEM deployed EDX (energy-dispersive X-ray) linear scanning was applied to explore thepresence of different chemicals in the biocomposite systems. The reinforcement effects of different fibers loading incomposite systems were also tested in terms of regression analysis and found that sisal/cotton interwoven fabrics existsignificant influence in the composite systems to increase the mechanical properties.
