Mechanical Behavior of Aluminum and Graphene Nanopowder-Based Composites

Abstract

Producing items that are of both high quality and long lasting is a difficult task for companies right now. There is a huge need for a wide range of engineering materials in today’s technologically advanced globe. The strength and qualities of the material determine the amount of material that may be used. Due to its excellent mechanical qualities and low density, aluminum-7075 alloy is mostly employed in transportation applications such as aerospace, marine, and vehicle production. This study addresses the fabrication and characterization of Al7075 semisolid metal matrix composite (MMC) reinforced with graphene nanoparticles. Samples are made with and without stirring graphene in aluminum-7075 at various temperatures of 800°, 830°, 860°, 890°, and 920°C. At these temperatures, the material is semisolid, so graphene is introduced and stirred into the molten liquid. The specimens meet the requirements of the American Society for Testing and Material (ASTM). The hardness, tensile strength, impact strength, and compression strength of various materials are evaluated and compared. Temperature lowers tensile strength, hardness, and compression. A scanning electron microscope (SEM) is used to examine the microstructure. The specimen is evaluated using ANSYS. Specimens with stirring have better mechanical characteristics. Graphene has high hardness and strength.

[Retracted] Investigation on Interlaminar Shear Strength and Moisture Absorption Properties of Soybean Oil Reinforced with Aluminium Trihydrate‐Filled Polyester‐Based Nanocomposites

“…The inclusion of EMS improved the nanocomposite's hydrophilic nature. Furthermore, the results show that the negative impacts of bioresin on porosity may be mitigated by using ATH augmentation [30]. According to the water uptake data, the biobased nanocomposite materials retain less water than natural fibres alone [31].…”

A Recent Trend on Additive Manufacturing Sustainability with Supply Chain Management Concept, Multicriteria Decision Making Techniques

“…Hence, the product price may be more affordable to the consumer [41]. ASTM [24] F2792 committee is formed to standardize the AM process in 2015. e AM process will overcome the traditional manufacturing process as well as soon [42]. e maturity model of AM involves the technology, production support by direct tooling, part support by direct manufacturing, and its application [43].…”

“…Conventional manufacturing has also withstood in the different fields of recent pieces of research like glass fiber, nanofillers, nanopowders, graphene, etc., and also the fault analysis using the IIOT. e CM can defend their business by following ways such as monitor, attack, adopt, acquire, and facilitate [21][22][23][24][25]. However, the main research gap prescribed that 3D printing will affect the CM in future [26].…”
