FUNCTIONALLY GRADED POLYMER NANOCOMPOSITES (FGPNCs) FILLED WITH NANO SIZED FILLER

摘要

A novel FGPNCs has been developed using polymer matrix (polyisoprene) and nanomaterials (amorphous carbon). Its performance is evaluated for structural application through storage modulus, loss tangent, tensile strength, modulus, hardness, hysteresis loss, tear strength, SEM, etc. The functionally graded nanocomposites show better properties i.e., modulus, tear strength, hysteresis loss and strain energy density compared to homogeneous composite at the same percentage of nano filler loading. As for examples, 20, 35 and 40% improvement in modulli at 50, 100 and 200% elongation with respect to homogeneous composites are observed where the average nanomaterial is 30% by weight.
