In the present work, punica granatum (Punica granatum L) straw discarded from the punica granatum cultivation has been explored for potential reinforcement to form green polymeric composites. To adjust the lignin content, the punica granatum straw fibers (PGF) were dissolved in an aqueous solution of sodium bicarbonate (10 %w/w) for different duration (1 day, 5 days and 10 days) at room temperature. The statistical parmeter associated with the fiber morphology was determined for different fiber conditions. The relationship between tensile properties and fiber transverse dimensions was investigated through mathematical model. Moreover, the bio-epoxy composites reinforced with punica granatum straw fibers were fabricated and characterized for static mechanical properties. The optimal composite composition was determined using TOmada de Decisao Interativa Multicriterio (TODIM) methodology. PGF-5D reinforced green composite with 30 wt% fiber loading was identified as the optimal composition. Finally, micromechanics evaluation was carried out to quantify the critical parameters playing a major role in controlling the structural-property relationships of the fabricated composites.

在目前的工作中，石榴（Punica granatum L已经研究了从石榴籽栽培中丢弃的秸秆，以潜在增强其形成绿色聚合物复合材料的能力。为了调节木质素含量，在室温下以不同的持续时间（1天，5天和10天）将石榴皮草纤维（PGF）溶解在碳酸氢钠水溶液（10％w / w）中。针对不同的纤维条件确定与纤维形态相关的统计参数。通过数学模型研究了拉伸性能与纤维横向尺寸之间的关系。此外，制备了用石榴皮草秸秆纤维增强的生物环氧复合材料，并对其静态力学性能进行了表征。最佳复合材料成分是使用TOmada de Decisao Interativa Multicriterio（TODIM）方法确定的。具有30 wt％纤维负载的PGF-5D增强绿色复合材料被确定为最佳组合物。最后，进行了微力学评估，以量化关键参数，这些参数在控制复合材料的结构-特性关系中起着重要作用。
