Method & Evidence

AimTo investigate the mechanical and physical performance of laminated composite panels made from waste jute and recycled polyester fibers in a polypropylene matrix for packaging applications, and to assess their disintegration behavior under simulated composting conditions.
MethodExperimental investigation and material testing
ProcedureEight different laminated composite panels were fabricated using varying ratios and stacking sequences of waste jute and recycled polyester fibers within a polypropylene matrix. The panels were subjected to tensile, flexural, and impact strength tests, as well as physical property assessments including density, water absorption, thickness swelling, and moisture content. A simulated composting burial test was conducted over four months to evaluate disintegration behavior.
