摘要

目前的环境状况表明,迫切需要含有主要自然元素的可持续材料来制造复合材料。在复合材料中使用天然纤维可以显著降低温室效应和制造合成纤维基聚合物复合材料的高成本。因此,本研究旨在研究香蕉纤维(BF)基环氧树脂填充核桃壳粉(WNP)复合材料的物理力学性能。通过固定BF比例和不同WNP百分比(0%,5%,10%,15wt . %)的混合和冷压进行制作。研究结果表明,添加WNP作为填料可以提高BF/EP复合材料的力学性能。这是因为WNP填料占据了复合材料中的空间,这些空间弥合了香蕉纤维和环氧基之间的间隙;同时,核桃粉在BF/EP复合材料中的掺入也大大提高了其耐磨性。采用扫描电镜(SEM)对复合材料的微观组织性能进行了研究。

Physio-mechanical & wear performance of banana fiber/walnut powder based epoxy composites
The present environmental condition indicates the immediate need for sustainable materials containing mainly natural elements for composite fabrication. Encouragement of natural fibers in composite materials can significantly reduce the greenhouse effect and the high cost of manufacturing synthetic fiber-based polymer composites. Hence, this study aimed to investigate the physio-mechanical properties of banana fiber (BF) fiber -based epoxy (EP) composites filled with walnut shell powder (WNP). Fabrication was carried out by mixing and cold pressing with fixed BF proportion and varying percentages of WNP (0%, 5%, 10%, 15 wt. %). The results obtained in the study suggest the mechanical properties of the BF/EP composite were enhanced with the addition of WNP as a filler. This is because the WNP filler occupies the spaces in the composite, which bridge the gaps between the banana fibers and the epoxy matrix; also, the inclusion of walnut powder in the BF/EP composites greatly enhanced their wear resistance. The microstructural properties of the composites were examined by scanning electron microscopy (SEM).
