Metal matrix composites are in high demand for various applications in the industrial sector and engineering firms. Therefore, new materials with enhanced mechanical and ecologically favourable characteristics must be designed and produced. This study focuses on the possibility of developing an aluminium matrix composite using agro-waste materials as reinforcement in preference to other industrial chemicals and materials. The morphological analysis carried out on the AA6061 + 15% snail shell at 100 μm showed the formation of homogenous particle size with stepped crystals. The micrographs of the developed composite were obtained using XRD (X-ray diffraction analysis), which indicated the presence of calcium and hydroxyapatite from the snail shell on the aluminium composite. Electrical analysis performed on the developed composite showed an increase in the conductivity from 32.03 Ωm⁻¹ to 34.59 Ωm⁻¹ as the snail shell reinforcements were increased, thus improving the capability of the developed MMC to transfer electricity due to the occurrence of the snail shell particulate within the composite.

AA6061/蜗牛壳复合材料的力学和电学性能研究

在工业部门和工程公司的各种应用中，金属基复合材料的需求量很大。因此，必须设计和生产具有增强的机械和生态有利特性的新材料。这项研究的重点是开发一种铝基复合材料的可能性，该复合材料使用农业废料作为增强材料，而不是其他工业化学品和材料。对 AA6061 + 15% 蜗牛壳在 100  μ下进行的形态分析m 显示形成具有阶梯状晶体的均匀粒度。使用 XRD（X 射线衍射分析）获得开发的复合材料的显微照片，这表明铝复合材料上的蜗牛壳中存在钙和羟基磷灰石。对开发的复合材料进行的电学分析表明，随着蜗牛壳增强材料的增加，电导率从 32.03 Ωm ^-1增加到 34.59 Ωm ^-1，因此由于蜗牛壳的出现而提高了开发的 MMC 的导电能力复合材料中的颗粒。
