Currently, bio-thermoplastic polymers are widely used as matrix reinforced with different kinds of natural fibers, because these bio-polymer are biodegradable, eco-friendly and nontoxic. Moreover, the natural fibers are one of the sustainable material for making composites for lightweight materials, which can deplete the use of man-made synthetic materials and reduce greenhouse effect. In this view, the use of waste bio-fiber as a reinforcement material in biobased composites for ecofriendly semi-structural applications. This research studied the extraction and characterization of waste fibers from water hyacinth plants and also fabrication of bioepoxy based ecofriendly composites from chemically treated water hyacinth fibers (WHFs). As far as we know, no work on this concept has been published so far. Water hyacinth is as an invasive and free-floating perennial aquatic plant known as Eichhornia crassipes. Firstly, raw and chemically treated water hyacinth fibers were characterized by various techniques such as chemical analysis, XRD, FTIR, TGA, DTG, SEM and AFM. The raw, NaOH and silane treated WHFs reinforced bioepoxy based composites are manufactured by casting method. Then, tensile, flexural, impact, hardness, thermal, dynamic, and surface morphology tests were carried out on composite specimens. This study confirmed that the WHFs can be used as a reinforcement material with bioepoxy polymer to develop fully biobased ecofriendly composites for production of lightweight structures.

目前，生物热塑性聚合物被广泛用作由不同种类的天然纤维增强的基质，因为这些生物聚合物是可生物降解的，生态友好的且无毒的。此外，天然纤维是用于制造轻质材料的复合材料的可持续材料之一，这可能会耗尽人造合成材料的使用并降低温室效应。根据这种观点，在生物基复合材料中，将废弃的生物纤维用作增强材料可用于生态友好的半结构化应用。这项研究研究了从风信子植物中提取废纤维的特性，并从化学处理的风信子纤维（WHFs）制备基于生物环氧树脂的环保复合材料。据我们所知，到目前为止，尚未发表有关该概念的任何文章。凤眼莲。首先，通过化学分析，XRD，FTIR，TGA，DTG，SEM和AFM等各种技术对未经处理的化学风信子纤维进行了表征。原料，NaOH和硅烷处理的WHFs增强生物环氧基复合材料是通过铸造方法制造的。然后，对复合材料试样进行了拉伸，弯曲，冲击，硬度，热，动力和表面形态测试。这项研究证实，WHF可以用作生物环氧聚合物的增强材料，从而开发出完全基于生物的环保复合材料，以生产轻质结构。
