Abstract

This study explored coconut shells in developing Al-Cu-Mg based nanocomposites for fabricating mould parts. The aim is to engineer alternate way through which income can be generated from agricultural wastes and recycling of industrial waste like aluminium cans. Al-Cu-Mg based nanocomposites were produced and characterised. Effects of carbonised and uncarbonised coconut shell nanoparticle (UCSNP) additions on properties of Al-Cu-Mg nanocomposites were compared. Maximum tensile strength was obtained at 10%vol uncarbonised coconut shell nanoparticle additions to Al-Cu-Mg. Increase in tensile strength and elastic modulus were noted with carbonised coconut shell reinforced Al-Cu-Mg nanocomposites against the decrease in the elastic (Young’s) modulus of the UCSNP/Al-Cu-Mg nanocomposites. Despite highest tensile strength of 10%volUCSNP/Al-Cu-Mg, 10%volCCSNP/Al-Cu-Mg nanocomposite is ranked as the best material in this study due to its optimum combination of properties including tensile strength, elastic modulus, tensile strain, impact energy and hardness values. Hence, it has been selected for fabricating open die mould parts to be used in compression sheet forming process for fabricating polymeric standard samples for tensile flexural analyses. Keywords: Al-Cu-Mg, Coconut, Shell, Nanoparticles, Mould fabrication

椰壳颗粒增强铝铜镁纳米复合材料在型腔模具零件中的应用

本研究探索了椰子壳在铝铜镁基纳米复合材料制造模具零件中的应用。其目的是设计另一种方式，通过这种方式可以从农业废物和铝罐等工业废物的回收中产生收入。制备了Al-Cu-Mg基纳米复合材料并对其进行了表征。比较了碳化和未碳化椰壳纳米颗粒(UCSNP)的添加对铝铜镁纳米复合材料性能的影响。在Al-Cu-Mg中添加10%体积的未碳化椰子壳纳米颗粒获得最大拉伸强度。碳化椰子壳增强Al-Cu-Mg纳米复合材料的拉伸强度和弹性模量增加，而UCSNP/Al-Cu-Mg纳米复合材料的弹性(杨氏)模量下降。尽管10%volUCSNP/Al-Cu-Mg纳米复合材料的抗拉强度最高，但由于其抗拉强度、弹性模量、拉伸应变、冲击能和硬度值的最佳组合，10%volCCSNP/Al-Cu-Mg纳米复合材料在本研究中被评为最佳材料。因此，它被选择用于制造开模模具零件，用于压缩片材成型工艺，用于制造用于拉伸弯曲分析的聚合物标准样品。关键词:铝铜镁，椰子，壳，纳米颗粒，模具制造

期刊介绍： "International Journal of Engineering Research in Africa" is a peer-reviewed journal which is devoted to the publication of original scientific articles on research and development of engineering systems carried out in Africa and worldwide. We publish stand-alone papers by individual authors. The articles should be related to theoretical research or be based on practical study. Articles which are not from Africa should have the potential of contributing to its progress and development.
