“…From the review above on the improvement of the electrical conductivity of Al/CNTs using AgNPs, it was cleared that AgNPs have a great potential in enhancing the properties of Al/CNTs. But the high demand and cost of AgNPs have been a major problem, which reduced the wide application of AgNPs to improves the properties of Al/CNTs [10][11][12][13]. However, in this work attempt was made to produce AgNPs using the biosynthesis method (Cashew leaves extract) to lower the cost of AgNPs used in the production of Al/CNTs..…”

The development of new advanced material of α-Al- carbon nanotubes (CNTs and green synthesis silver nanoparticles (GAgNPs) superconductor nanocomposites was sudied. Green synthesis silver nanoparticles (GAgNPs) was used for the decoration of CNTS. The composites were by modified spark plasma sintering (SPS). The microstructure, strength and electrical conductivity of the nanocomposites were determined. The formation of sub-grain in the Al-4%CNTs + 2%GAg.NPs composite generates more dislocation density. The addition of GAgNPs to Al-CNTs significantly enhanced the ductility mode of fracture associated with the AlAg3(110) and AlAg2(100) phases and the small sub-grain formed at the surface. It can be concluded that a higher strength, electrical conductivity can be made from the developed nanocomposite.

“…According to the theories of Cox and Kelly [2,3], the degree to which the filler is reinforced is determined by its stiffness and aspect ratio, as well as the adhesive strength between the filler and the polymer matrix. Polymer clay nanocomposites have garnered great attention when it was discovered that by adding nano-sized clay particles, the polymer characteristics may be significantly enhanced [4,5]. The inclusion of nano clay particles greatly improves the characteristics of thermoset unsaturated polyester [6].…”

This study aims to reveal the consequence of thickness reinforcement on Fiber Laminates (Polyester Resin, Glass Fiber, Aluminum, and Bentonite) and to see if it can enhance the mechanical properties and resistance of laminates. Glass fiber reinforced polymer composites have recently been used in automotive, aerospace, and structural applications where they will be safe for the application s unique shape. Hand layup was used to fabricate three different combinations, including Aluminium /Glass fiber reinforced polyester composites (A/GFRP), Bentonite/Glass fiber reinforced polyester composites (B/GFRP), and Aluminium&Bentonie/Glass fiber reinforced polyester composites (AB/GFRP). Results revealed that AB/GFRP had better tensile strength, flexural strength, and hardness than GFRP and A/GFRP. Under normal atmospheric conditions and after exposure to boiling water, hybrid Aluminium&Bentonite and glass fiber-reinforced nanocomposites have improved mechanical properties than other hybrid composites. After exposure to temperature, the flexural strength, tensile strength and stiffness of AB/GFRP Composites are 40 % higher than A/GFRP and 17.44% higher than B/GFRP Composites.

“…Due to its wide range of chemical compatibility, temperature range, low compression set, and excellent ageing characteristics, fluorocarbon rubber is the most significant single elastomer developed in recent history. Fluorocarbon elastomers are highly fluorinated carbon-based polymers used in several applications to resist harsh chemical and ozone attacks [1][2][3][4]. The working temperature range is considered to be -26°C to +205°C /230°C (-15°F to+400°F/440°F).…”

The usage of seals in several applications like aircraft engines is mostly made of Fluorocarbon (FKM) elastomer. They are coloured products that enable easier identification based on the applications. In such seals, fillers like carbon black cannot be added to reinforce and improvise the mechanical properties since carbon black does not make it possible to add colours. The properties after ageing are also very critical in sealing application, and they must also be improved. Also, Nanocomposites are the modern and growing trends in the field of polymers that show enormous changes in the properties of the polymers without affecting their basic properties. So, the need for improvisation of FKM seals and the concept of Nanocomposites can be merged to form FKM Nanocomposites with Nano clay and Nano silica as the fillers. The objective of this project is to improve the mechanical properties, better retention of properties after ageing and after fluid interaction of the FKM seals with the aid of Nanofillers. Different proportions of FKM nanocomposites were prepared using modified Nano Kaolin Clay & modified Montmorillonite clay (Cloisite grades). Various mechanical properties like tensile strength, tensile modulus, elongation at break, compression set and tear strength etc., were studied. The test results have shown good improvements while increasing the filler loading. This is helpful to manufacture seals of desired colours thereby avoiding the difficulties faced in the carbon black-filled FKM compounds.
