ABSTRACT

In order to advance the development of bio-composite materials, studies are being carried out on the potentials of using reinforcements from a natural origin in polymer matrixes. In this study, thermal conductivity, water absorption, and mechanical properties of calcined eggshell particles-treated sisal fiber hybrid reinforced epoxy composites were investigated in order to ascertain its potentials for use as structural materials. Calcined eggshell particulate (CEP) was obtained from chicken eggshell while treated sisal fibers (TSF) were obtained from the Agave sisalana plant. Both processed reinforcements were incorporated into an epoxy matrix using the hand lay-up method for the development of the bio-composites. Thermal, water absorption and mechanical behavior tests were carried out on the developed composites and the control sample. Analysis of the results showed that the presence of the bio-fillers in the epoxy matrix enhances the insulating, resistance to water uptake, and mechanical properties of the composites compared to the unreinforced epoxy matrix. It was concluded that these bio-fillers could be effectively used as reinforcements in a polymer matrix for the production of green composites.

改性植物纤维素纤维-动物废弃物杂化增强环氧复合材料的热稳定性、吸湿潜力和力学性能

摘要

为了推进生物复合材料的发展,正在研究在聚合物基质中使用来自天然来源的增强材料的潜力。在这项研究中,为了确定其用作结构材料的潜力,研究了煅烧蛋壳颗粒处理的剑麻纤维杂化增强环氧树脂复合材料的导热性、吸水性和机械性能。煅烧蛋壳颗粒 (CEP) 是从鸡蛋壳中获得的,而处理过的剑麻纤维 (TSF) 是从龙舌兰剑麻植物中获得的。使用手糊法将两种加工过的增强材料结合到环氧树脂基质中,以开发生物复合材料。对开发的复合材料和对照样品进行了热、吸水和机械性能测试。结果分析表明,与未增强的环氧树脂基体相比,环氧树脂基体中生物填料的存在增强了复合材料的绝缘性、抗吸水性和机械性能。得出的结论是,这些生物填料可以有效地用作聚合物基质中的增强材料,用于生产绿色复合材料。
