Introduction: The present study has demonstrated the effect of short jute fiber on physical, mechanical and erosion wear performance of PLA based composite. Problem Statement: An attempt has been made to develop and investigate the environment friendly and biodegradable composites based on jute fiber and PLA composite. Materials and Method: The erosion wear performance was assessed on Air-jet erosion tester. The design of experiments was prepared as per Taguchi orthogonal array L16 under for different factors of impact velocity, impingement angle, erodent size and jute fiber fraction and level of each factor was kept four. ANOVA was applied to find the best significant factor affecting erosion rate of composite. Main Results: The finding of results indicated that the density significantly increased with the addition of jute fiber and in parallel, it indicated the increment in the void content. The mechanical properties like hardness, tensile strength, flexural strength, impact strength and fracture toughness of PLA based composite reinforced with 15 wt.-% jute fiber were increased by 59%, 233%, 42%, 62% and 168% respectively. On the other hand, the thermal conductivity of the composite was decreased by 31% with the addition of 15 wt.-% of jute fiber. The minimum erosion wear rate was obtained for 15 wt.-% of jute fiber under impact velocity of 35 m/sec and angle of impingement of 90° and erodent size of 250 µm. Finally, ANOVA concluded that the impact velocity and jute fiber fraction played the most important role in influencing the erosion wear rate of PLA composite. Recommendation: For many construction and structural applications, jute PLA/fiber composite can be suitable due to excellent mechanical properties and low thermal conductivity.

Powder metallurgy is an effective method to give near net shape to powder particles. In this paper, the influence of powder particle size, lubricant and compaction load on hardness and wear loss has been investigated as it influences the compact. Electrolytic iron powder (250 mesh to 300 mesh and 300 mesh to 350 mesh) with zinc stearate (0 weight % to 2 weight %) was used for preparing the samples. Green samples were prepared by cold compaction process at different loads (400 kN, 450 kN and 500 kN). Pre-sintering was done at 550 °C. Taguchi's (L 18 ) mixed level model was used to develop the regression equation for hardness and wear loss. The maximum hardness of 79 HRB was achieved with 300 mesh to 350 mesh particle size and 500 kN compaction load. Minimum wear volume loss was observed with samples having composition of 250 mesh to 300 mesh size electrolytic iron powder at 500 kN compaction load and 1 weight % lubricant content.

“…In the quest to enhance the hardness and strength of aluminum alloys, researchers have incorporated various reinforcement particles, such as silicon carbide (SiC) and boron carbide (B4C), through the stir casting process (Das et al, 2014;Sankarlal & Kuppusamy, 2018). These additions significantly improve the mechanical properties of the composite materials, particularly hardness and tensile strength (Mishra et al, 2019a). The chemical analysis of the composite materials confirms the composition of the aluminum alloy, such as Al6061, using techniques like optical emission spectrometry.…”

Aluminum alloys are widely used in different engineering application areas, such as aerospace, automotive, and marine industries. However, their properties need some improvement in order to enlarge their application area. Thus, the objective of the study was to improve the physical and mechanical properties of Al6061 aluminum alloy by reinforcing it with nano-Al2O3 and micro-quartz particles. The investigation primarily was focused on studying the impact of quartz particles on the mechanical and physical properties of an Al6061/nano Al2O3/quartz hybrid composite. The hybrid composite was developed using a stir casting technique, by varying the weight percentage of quartz particles at 3%, 6%, and 9%, while maintaining a constant weight percentage of nano-Al2O3 at 3.5%. To evaluate the composite's properties, test samples were prepared according to ASTM E9-09 and ASTM E23 standards for hardness, compressive strength, creep, and impact energy absorption, respectively. The results of the investigation demonstrate that, with the addition of 9 wt.% of micro-quartz particles and 3.5 wt.% of nano-Al2O3 nanoparticles, all mechanical and physical properties of the matrix were improved, except for the impact strength. Based on these results, the developed hybrid composite material can be recommended for light weight automotive spare parts such as brakes and clutch discs.
