Recent Progress in Hybrid Aluminum Composite: Manufacturing and Application

Abstract

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.

Mechanical behaviour of stir cast aluminum matrix composites reinforced with silicon carbide and palm kernel shell ash

“…The single reinforced composite (sample B1) with SiC only, was found to have highest density, higher than the unreinforced Al (6063) alloy. This is due to the higher density of SiC (3.21 g/cm 3 ) compared to that of Al alloy (2.7 g/cm 3 ). The other single reinforced composite with only PKSA (sample B5) had the lowest densities due to the very low density of PKSA (0.93 g/cm 3 ).…”

“…This is due to the higher density of SiC (3.21 g/cm 3 ) compared to that of Al alloy (2.7 g/cm 3 ). The other single reinforced composite with only PKSA (sample B5) had the lowest densities due to the very low density of PKSA (0.93 g/cm 3 ). The same trend of behaviour was observed for the other classes of the composites (8 wt.%, 10 wt.% and 12 wt.%), which is an indication that the introduction of varying percentages of the PKSA reinforcement into the composites effectively reduced the theoretical densities of the composites produced.…”

“…The ascast samples were machined as follows: gauge length of 30 mm, diameter (D) of 6 mm, circumferential notch diameter (d) of 4 mm and notch angle of 60 o . K 1c values were calculated using equation (3). SEM-fractographs of representative samples were also obtained to determine the fracture mode for the AMCs.…”

“…As the proportion of PKSA increases, dispersion strengthening gradually dominates, attaining an optimal effect at reinforcement ratio 1:1. Secondly, thermal mismatch between the high expansion metallic matrix and the low expansion ceramic reinforcements, effective transfer of stress from matrix to the reinforcements and interactions between the dislocations and particulates (strain hardening effect), and grain refinement of the matrix (Hall-Petch effect) can all be good reasons for the strengthening of the composites produced [2,3,7,[28][29][30].…”

“…This quest for economical and energy-efficient materials, with better physical, mechanical, thermal and tribological properties, in the automobile, aerospace and other applications is tailoring research in the direction of consideration of agro-waste derivatives as reinforcement substitute for the development of hybrid reinforced aluminum matrix composites (HAMCs) [1,2]. Hybrid aluminum matrix composites present new generation of aluminum matrix composites (AMCs) that have the potential to substitute single reinforced composites due to improved properties [3][4][5]. Recent researches have shown that agro/ industrial wastes are effective as contemporary reinforcements in HAMCs [2,6].…”
