“…In addition, the usage of lightweight materials is becoming more popular since they are easier to produce, take up less room, need fewer components during assembly, look better, and ofer superior protection against corrosion assault. Tese reasons have inspired the present generation of developers to produce novel composites, which are currently produced in vast quantities and to exacting standards [14][15][16][17][18]. Te bulk of the structural loads are carried by fbrous reinforcement, which provides macroscopic stifness and strength.…”

The fabrication of the Al2219 + Si3N4 composites was done by means of stir casting process. The specimen was subjected to microstructural studies. The density of Si3N4 employed in the fabrication of the composites has been evaluated. Generally, the density of the composites increases as the weight percent of Si3N4 increases. TGA and DTA were performed at temperatures ranging from 30°C to 800°C, with some mass loss noted as well as the thermal stability of an AA2219 matrix improved. Under various parameters of applied load, operating duration, and speed, the wear behaviour of the produced aluminium matrix composite (AMC) was examined. Corrosion behaviour was examined using potentiodynamic polarization curve data, and it was discovered that the rate of corrosion decreases with increasing Si3N4 content, adding to the AA2219 matrix. The research work is intended to produce a totally new composite material with various compositions of reinforcement and to investigate their mechanical properties and a result of simulation.
