The Study on Electrical and Mechanical Impact of Snail Shell Reinforced AA6061 Matrix Composites

There is a demand for lightweight and low-cost engineering materials with enhanced strength especially in automotive, aerospace, and structural applications in this modern age’. This study focused on developing an aluminium matrix composite using the stir casting method with snail shells of particulate size 75µm with varying proportions (4%, 8%, 12%, 16%) in order to enhance the properties of the composite such as tensile strength, hardness etc. The aluminium composites were studied and analyzed using the Brinell hardness tester for microhardness properties, UTM SM1000 for ultimate tensile strength behavior, scanning electron microscope equipped with energy dispersive spectrometer were used in studying the surface morphology and the elemental identification of the composite, X-ray diffraction was also used to categorize the crystalline phase of the composite. The results showed the XRD micrographs of the produced composite revealed the presence of calcium and hydroxyapatite derived from the snail shell on the aluminium composite. The diffractive pattern revealed a large number of reinforcements with stable intermediate phase Ca10(PO4)6(OH)2, Ca2Al3SIO4, and Ca2SIO4 and so on. The electrical properties increased in conductivity due to the presence of the snail shell particulate within the composite from 31.9693Ωm-1 to 34.6500Ωm-1, thus increasing the capacity of the composite to conduct electricity. Furthermore, the ultimate tensile strength showed a significant change of 35.8% with the maximum tensile strength of 98.89MPa, achieved at 8% wt. snail shell. The hardness increased proportionally from 55.2HRB to 63.5HRB. Based on the outcome of experiments, this research has shown the possibility of using snail shell particulates as reinforcement in aluminium metal matrix composite and will help to improve the productivity and reliability of component made of AA6061 + 8% snail shell at 75µm.
