An experimental investigation on the effect of lithium and alkali resistant glass fiber on aluminum AA5383 fabricated by the stir-casting process

Abstract

The purpose of this experimental research is to investigate composite materials that could be utilized in shipbuilding application. These materials are fabricated by employing bare material such as aluminium 5383 alloy and are then reinforced with lithium and alkali resistant glass fiber (ARGF). Lithium, which is known for its strong ductile and malleable properties, can be added to aluminium alloy 5383 in order to bring about a reduction in the overall weight of the materials. ARGF used as a reinforcement material with aluminium 5383 to empower the more resistant to corrosion. In the course of this experimental study, four samples will be manufactured by adjusting the percentage of ARGF used. The following tests were carried out in order to optimise the chemical composition of composites: the brilnell hardness test, the tensile test, the charpy impact test, the double shear test, and the sodium chloride (Nacl) corrosion test. From the results, it was discovered that S4 had a maximum brinell hardness value of 123 BHN, the tensile strength of the sample S4 had a maximum value of 372 MPa, the highest impact strength of the sample S4 was found to be 10 KJ/m2, and the maximum double shear strength of the sample S4 was found to be 96 MPa. Add to that, S4 had good corrosion resistance qualities. The study may provide insights into the sample S4 have a potential applications of the composite material in various industries, such as aerospace, automotive, and manufacturing. The incorporation of reinforcing materials such as lithium and ARGF into metal matrices can potentially improve their mechanical and corrosion properties, which may lead to the development of new materials with improved performance characteristics.
