Abstract

This research work has been focused in combination of the new method of severe plastic deformation (SPD) on hybrid composite materials to the accuracy of the simulation results in the process of making aluminum alloy reinforced Al2O3/SiC ceramic. Usually using conventional processes. The latest method was developed by repetitive press-roll forming (RPRF) as a processing of ceramic-reinforced composite materials. The Simulations were carried out to validate the experimental results. Supported by the results of the strength testing conducted for composites with the hybrid reinforcement by having Ultimate Tensile Strength (UTS) values that correspond to 123 N/mm2, 130 N/mm2, and 124 N/mm2 for the hybrid composites of 2 layers, 4 layers, and 6 layers respectively. This is the best result among processes that have been developed, such as accumulative roll bonding (ARB). The experimental results prove that the SPD kind of RPRF process can significantly increase the UTS and hardness values in aluminum matrix-based composites type AA1100/5052. Samples with SiC reinforcements have the highest mechanical properties compared to the other reinforcements (Hybrid and Al2O3), with the resulting UTS value of 163 MPa and the resulting hardness value of 46.42 HV. The application on this experiment is a matrix of plate that is affixed where the surface of the face is sprinkled with ceramic Al2O3/SiC material as a reinforcement
