“…The results show that the mechanical properties of the TSS-C sample are better than the other samples, with higher density and microhardness, which is of great significance for the application of metal matrix composite in the automotive and aircraft industries. Sachin [75] studied the mechanical properties and specific wear rate of aluminum alloy Al6061 reinforced with different weight percentages of silicon carbide (SiC). Metal matrix composite were prepared by stirring-casting, and two SiC particles with different weight percentages were added into Al6061.…”

Advanced composite materials have excellent performance and broad engineering application prospects, and have received widespread attention in recent years. Advanced composite materials can mainly be divided into fiber-reinforced composite materials, laminated composite materials, matrix composite materials, and other composite materials. This article provides a comprehensive overview of the types and characteristics of advanced composite materials, and provides a comprehensive evaluation of the latest research on structural strengthening and resilience improvement in advanced composite materials from the perspectives of new methods, modeling optimization, and practical applications. In the field of fiber-reinforced composite materials, the hybrid technology of carbon fiber and glass fiber can achieve dual advantages in combining the two materials. The maximum increase in mechanical properties of multilayer sandwich RH plate by hybrid technology is 435.4% (tensile strength), 149.2% (flexural strength), and 110.7~114.2% (shear strength), respectively. In the field of laminated composite materials, different mechanical properties of laminated composite materials can be obtained by changing the deposition sequence. In the field of matrix composites, nano copper oxide particles prepared by nanotechnology can increase the hardness and tensile strength of the metal matrix material by 77% and 78%, respectively. In the field of other composite materials, viscoelastic materials and magnetorheological variants have received widespread attention. The development of composite materials benefits from the promotion of new methods and technologies, but there are still problems such as complex preparation, high cost, and unstable performance. Considering the characteristics, application requirements, cost, complexity, and performance of different types of composite materials, further improvements and innovations are needed in modeling and optimization to better meet practical engineering needs, such as the application of advanced composite materials in civil engineering, ships, automobiles, batteries, and other fields.

The applications of AA6082 alloys in the structural and transport are found to be more due its light weight. To improve strength to weight ratio and stress resistance, the carbides/oxides are added and this will leads to improvement in the mechanical properties and high stress sustainability. In this research work, AA6082 Metal Matrix Composite (MMC) is manufactured through the ex-situ casting process with the Silicon Carbide (SiC) reinforcements of 2.5 & 5 wt% and the microstructure evolution, hardness, dry sliding wear behavior and tensile properties of MMCs are investigated. As-cast AA6082 showed the dendritic microstructure with intermetallic eutectics. The presence of SiC particulates in AA6082 resulted in decreased grain size and equixed grains. The hardness of the tested as casted AA6082 samples was found to be 81 HV which has been increased to 93 HV and 107 HV and the tensile strength of AA6082 is increased by 16% and 41% by addition of 2.5 wt% SiC and 5 wt%SiC respectively due to the presence of the SiC particulates. At the same time coefficient of friction of AA6082 is found to be decreased by 11.8% and 20.5% for the testing load of 10N and the corresponding decrease in wear rates were found to be 50.8% and 70.3% respectively. The worn surface showed the continuous groove parallel to sliding direction with short cracks, bidirectional rough grooves with peeled-off SiC, unidirectional smooth scratches along the sliding surfaces for as-cast AA6082, AA6082-2.5 wt SiC and AA6082-5 wt SiC respectively that indicates the significant effects of SiC particulates on wear mechanism.
