Thermal Stability, Moisture Uptake Potentials and Mechanical Properties of Modified Plant Based Cellulosic Fiber-Animal Wastes Hybrid Reinforced Epoxy Composites

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.

摘要

为了促进生物复合材料的发展, 人们对天然增强材料在聚合物基体中应用的潜力进行了研究. 本研究旨在探讨经煅烧蛋壳粒子处理剑麻纤维混杂增强环氧复合材料之热导率、吸水率及力学性能, 以确定其作为结构材料之潜力. 以鸡蛋壳为原料制备了煅烧蛋壳粉(CEP) 和剑麻纤维(TSF). 两种处理后的增强体均采用手糊法加入到环氧树脂基体中, 以开发生物复合材料. 对制备的复合材料和对照样品进行了热、吸水和力学性能测试. 结果表明, 与未增强环氧树脂基体相比, 生物填料的加入提高了复合材料的绝缘性、抗吸水性和力学性能. 结果表明, 这些生物填料可以有效地用作聚合物基体中的增强体, 用于生产绿色复合材料.
