This present work mainly focused to utilize the natural resources such as Banyan short fiber, wheat gluten (WG) for making the series of different bio degradable polymer composites. The WG was blended with the polyhydroxybutyrate (PHB) bio polymer in the ratios 20:80, 30:70, 40:60 percentage of WG and PHB polymer respectively. A total of nine different ecofriendly nano filler bio composites with the size 300 * 300 * 3 mm were developed through hand layup method with the aid of hydraulic press by changing the dispersed phase (short banyan fiber) composition like 10, 20, and 30 percentage with continuous phase of 90, 80 and 70 percentage (bio polymer blends). The fabricated bio composite laminates were initially tested according to ASTM standard for density, tensile, impact, thermogravimetric analysis, and surface texture analysis. Then the drilling was carried out on the three different composites (30

This study set out to create epoxy composites using MB fibers without chemical treatment. As a reinforcement for polymer composites, bark fibers have lately become more common. Epoxy composites reinforced with Mesquite bark (MB) fibers were the subject of this paper’s thermal, mechanical, and morphological property analysis. The composites contained 5, 10, and 15 mm MB fibers in a variety of counts and weight percentages (from 5 to 30 wt.

Bio polymer derived from the biodegradable natural plant resources are getting wide attention in production of light weight high performance composite materials offsetting the utilization of fossil fuel based synthetic man-made polymers, due to their eco friendliness, lower environmental impact, and higher thermal stability. Even though, the challenges in achieving higher mechanical properties of biopolymers composites need to be addressed through adding the natural fillers and bio fibers in various proportions. This present work employs the Moringa Oleifera (MO) fibers, Polysaccharide (PS) fillers to reinforce with the polylactic acid (PLA) bio resin to fabricate the series of six different bio composites through compression molding method by changing the volume fractions of raw materials as 10:5:85, 15:5:80, 20:5:75, 10:10:80, 15:10:75 and 20:10:70

This study involved the fabrication of AZ61 magnesium alloy reinforced with nano-sized Zinc Oxide (nZnO) particles by a squeeze-casting process, and examined its properties at different melt temperatures (720, 750, 780, and 810 °C). Mechanical characterization encompassed tensile, hardness, and impact, also wear testing, supplemented by comprehensive microstructural investigation were studied. Experimental findings indicated that melt temperature is crucial in influencing the composite’s ultimate characteristics. A melt temperature of 780 °C resulted in superior dispersion, a refined grain structure, and improved compatibility for plastic deformation, attributed to sufficient superheat and efficient stirring at a squeeze pressure of 80 MPa. The AZ61/nZnO composite demonstrated enhanced wear resistance relative to the base alloy, with diminished wear rates resulting from the synergistic effects of nZnO reinforcements, optimized load transmission, and decreased porosity. The wear rate analysis emphasized the effects of sliding velocity, applied stress, and surface topography on material degradation during sliding. Microstructural analyses validated superior particle dispersion and diminished porosity at optimal values, directly enhancing mechanical performance.

Wire Electrical Discharge Machining (WEDM) is a sophisticated metal removing process, which is appropriate for creating intricate patterns in conductive materials like metal matrix composites. The current study examines WEDM for AA6351/AlN composites to identify various parameters and achieve performance metrics concerning lowest SR and maximum MRR. The composite was created through stir casting technique with 88 wt
