Due to their excellent properties, the requirement for materials with higher characteristics has transformed primary alloy into composite materials. Composites are particularly essential for various applications in numerous engineering purposes because of their superior mechanical, physical, and machining qualities. Compared to traditional materials, aluminum composite has various advantages and superior characteristics. To reduce production costs and obtain the desired properties, the researchers developed a hybrid aluminum matrix composite (HAMC), an AMC with two or more types of reinforcement. Further studies were conducted to improve the qualities and manufacturing processes of composites to improve their properties. Various methods are available to HAMC manufacturing, and different manufacturing methods result in different characteristics of HAMC composites, viewed from physical properties, mechanical properties, and production cost. In addition, differences in the type, size, and amount of reinforcement produce various hybrid composite properties, especially in the physical properties, mechanical properties, and tribological behavior of HAMC. This work presents a comprehensive review of recent progress in HAMC study with various reinforcement particles, manufacturing techniques, physical, mechanical, and tribological properties of HAMC. On the other side, this work provides discussion for application, challenges, and future work conducted for HAMC development.
High energy demand is leading to the replacement of fossil energy with renewable sources such as solar energy. Solar cells are devices used to generate solar energy. However, when exposed to sunlight with high intensity, a solar cell can suffer a decrease in performance due to overheating. This issue can be addressing by adding a cooling system. This study used a passive cooling system by adding a heat sink with fins to the body panel of the solar cell. The advantage of the passive cooling system is that it does not require additional energy. The number of fins and types of material were varied to obtain the best passive cooling system. The number of fins used was 5, 10, and 15, and the materials used were aluminum and copper. The wind speed vector and the temperature distribution were investigated through simulation. The results showed an increase in the number of fins provided better cooling capacity and increased the photovoltaic performance. The best cooling capability and performance were obtained using 15 fins with a copper base and fin heat sink materials. The decrease in temperature and the increase in efficiency were 10.2 °C and 2.74%, respectively. Therefore, the use of passive cooling system based on heat sinks with fins could provide a potential solution to increase performance and prevent overheating of photovoltaic (PV) panel systems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
