“…As a result, reinforcements should only be applied up to a certain weight fraction; otherwise, they are pointless. This can be attributed to the agglomeration and increasing porosity with higher reinforcement content, as well as the optimal weight fraction of reinforcement varying amongst composites [10,11]. AA 6061 was mixed with (2.5 to 7.5wt%) of SiC-Al2O3 and (0.5 to 2.5wt%) of rare earth CeO2 by Vipin et al Following the inclusion of cerium oxide, the findings showed improved mechanical characteristics with decreased porosity (rare earth particles).…”

In order to meet the requirements of lightweight, high strength, and wear resistance, metal matrix composites are being manufactured with increasing interest, according to recent advancements in material science. Alumina (Al2O3) and Graphite (Gr) were added to the aluminum alloy matrix (AA6061) to increase the dry sliding wear resistance and to explore the impact of normal applied load and sliding speed on the coefficient of friction as well as its wear behavior. The composites were made by the stir casting technique. Hardness and tensile strength were two examples of mechanical qualities that have been assessed. Compared to the unreinforced aluminum alloy, the tensile strength of the metal matrix composites was improved by 17.7%, and the hardness increased by 44.1% at a loading of AA6061 (90wt%)/ Al2O3 (5wt%)/Gr (5wt%). A pin-on-disc tribometer was utilized to analyze the dry sliding tribo-behaviors of AA 6061 alloy reinforced with Al2O3 and Gr by varying the applied load and the sliding distance. The wear resistance of aluminum alloy reinforced with Gr (5wt%)/Al2O3(5wt%) increased by 85.0% when the load was applied at 25N compared to unreinforced aluminum alloy, and the frictional coefficient decreased by 58.0%. Additionally, an optical microscope and scanning electronic microscope were used to assess the worn surfaces.

“…Figure 12 shows the presence of SiC and Graphite particles are uniformly distributed. The dendritic structure was equally shaped and shows a uniform distribution, which indicates improvements in strengths up to 6 wt.% after that due to particle agglomeration the strength decreased [25]. The wear rate of Al MMC's and base alloy increased exponentially with increasing load and sliding distance, as shown in Figures 13-15.…”

This study investigates the effects of incorporating graphite into a Al6061/SiC hybrid metal matrix composite on its mechanical and wear properties. The composites are fabricated using a stir casting technique, with SiC and Graphite particles added in different weight percentages ranging from 2-8%. Mechanical properties such as hardness, tensile strength, flexural strength, and compressive strength are evaluated. Results show that the composite with 6 wt.% of hybrid reinforcement exhibits significant improvement in hardness (30%), tensile strength (10.82%), compressive strength (68.14%), and flexural strength (85%) compared to pure Al6061 alloy. Furthermore, a wear test is performed using a pin-on-disc machine under dry conditions to assess the influence of parameters on the wear rate and coefficient of friction (COF). Tests are conducted at various loads (1-3 kgf), sliding speeds (150-450 rpm), and sliding distances (1000-2000 m). Among all reinforcements, the composite with 6% hybrid reinforcement exhibits the lowest wear rate and COF. Overall, this study provides valuable insights into the mechanical and wear properties of Al6061/SiC/graphite hybrid composites and highlights their potential for various industrial applications. These findings may pave the way for further research in the field of metal matrix composites and their applications.

The quality of particleboard made from broad-leaved acacia branches and PVAc adhesive was investigated. A non-factorial completely randomized design (CRD) with adhesive contents of 10%, 15%, and 20% was employed. The parameters for testing physical properties included moisture content, density, water absorption, and thickness swelling. The parameters for testing the mechanical properties were modulus of elasticity, modulus of rupture, internal bonding, and screw withdrawal resistance. The results indicates that the concentration of PVAc adhesive has a significant effect on both physical and mechanical properties of the fabricated particleboards. The LSD further test indicates that particleboard with 20% adhesive content has the highest value in strength tests and meets the Indonesian National Standard (Standard Nasional Indonesia/SNI) 03-2105-2006. It is suitable for non-structural indoor (interior) element.
