Bio-reduction of composite materials is the modern approach to facilitate the researchers to avoid toxic chemical exposure during reduction process. In this study, the green reduction of graphene oxide using Abutilon indicum (Tamil name: Thuthi) plant leaves extracted from various solvents were used as green filler material (0.3, 0.6 and 1 wt.%) in glass fibre epoxy composite. Compression moulding process was adopted to fabricate bio-reduced graphene oxide (BGO) filler incorporated polymer matrix composite. Tensile, flexural, toughness, impact test and fracture surface morphology analysis have been conducted over developed composite. Flame retardancy behaviour was studied based on UL94 standard. Outcome of the study revealed that Abutilon indicum act as the better reducing agent to reduce graphene oxide. XRD, FTIR results depicts the proper distortion of graphite flask. Addition of BGO in polymer matrix improvises the tensile, flexural and impact strength of matrix material up to 28%, 55% and 80%. Herein addition of 0.6 wt.% of BGO showcase better fracture toughness and flexural strength, further increment in BGO show negative effect in strength. Occurrence of delamination failure was notified in fracture surface morphology.

复合材料的生物还原是促进研究人员在还原过程中避免有毒化学物质暴露的现代方法。在这项研究中，使用从各种溶剂中提取的Abutilon indicum（泰米尔语名称：Thuthi）植物叶绿色还原氧化石墨烯被用作玻璃纤维环氧树脂复合材料中的绿色填充材料（0.3、0.6 和 1 重量％）。采用压缩成型工艺制造生物还原氧化石墨烯（BGO）填料掺入聚合物基复合材料。对开发的复合材料进行了拉伸、弯曲、韧性、冲击试验和断裂表面形态分析。基于UL94标准研究阻燃行为。研究结果表明，Abutilon indicum作为还原氧化石墨烯的较好还原剂。XRD、FTIR 结果描绘了石墨瓶的适当变形。在聚合物基体中加入 BGO 可将基体材料的拉伸、弯曲和冲击强度提高 28%、55% 和 80%。在此添加 0.6 wt.% 的 BGO 显示出更好的断裂韧性和弯曲强度，BGO 的进一步增加显示出对强度的负面影响。分层失败的发生是通过断口形貌来通知的。
