This current work aims to prepare a flexible elastomeric microwave shielding composite material with good mechanical and thermal properties by dispersing Fe 3 O 4 and titania hybrid nano-particles. The primary aim of this research work is to prepare a high strength and high thermal stable flexible natural rubber composite with higher wave attenuation coefficient against 'X (8-12 GHz)' and 'Ku (12-18 GHz)' band microwave frequencies. The Fe 3 O 4 -Titania hybrids were prepared using low energy ball milling and the hybridization effect was confirmed using transmission electron spectroscopy. The prepared Fe 3 O 4 -Titania hybrids were surface-treated using 3-Aminopropyltriethoxysilane via wet solution method to avoid agglomeration. The natural rubber flexible composite was made by two-roll milling with recommended process parameters. The mechanical and thermal results showed improved tensile strength, modulus and mass decomposition. The highest tensile strength of 60 MPa was observed for composite contains 1.0 vol% of Fe 3 O 4 -TiO 2 particles. Similarly, the highest thermal stability of 385°C is observed for composite contain Fe 3 O 4 -TiO 2 particles. The X and Ku band microwave attenuation behaviour revealed the highest attenuation of 28.1 dB for 1.0 vol% of Fe 3 O 4 -TiO 2 particle dispersed rubber composite in Ku band frequency. These mechanically toughened thermally stable and high microwave attenuation flexible composites could be used as EMI shielding material at antennae and other telecommunication devices where electromagnetic wave interference creates crucial issues.

“…Life prediction is an important criterion for the seals. The life prediction can be done with the help of a stress relaxometry which predicts life by the evaluation between the Stress and Strain where one of the parameters is kept constant and the other is varied [11][12][13][14][15]. From this study, a clear assessment of the life of the product can be done.…”

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.

“…As a result, the inbound micro cracks were unable to provide enough motive force in the matrix phase to overcome total plastic deformation. [26] However, it should be highlighted that adding a reasonable amount of biochar particle to the resin matrix increased the mechanical properties. Biochar's excellent adherence and void filling effect in resin matrix absorbed a lot of load and provided a high load bearing effect.…”

High toughness epoxy bio-composites were prepared using Caryota urens fiber and biochar particle for light weight and low cost engineering applications.The main aim of this research was to study the effect of adding biochar along with C. urens fiber in epoxy resin composite and its properties. The biochar used in this present study was prepared from coconut shell using pyrolysis process. The composites prepared with 5 vol% of biochar gives highest tensile strength and modulus of 172 MPa and 6.7 GPa. Similarly, the biochar of 7 vol% in epoxy resin reduced the wear volume to the greater extend. Moreover, a highest dielectric constant and loss factor of 6.2, 1.6, and a thermal conductivity of 0.33 W/mK with high hydrophobic contact angle of 70 was observed for composite made using 7 vol% of biochar. These improved dielectric, mechanical, barrier and tribological properties composite could be used as microwave shielding material in electronic gadgets, signal processing units and other telecommunication devices as shielding material with good mechanical properties required.
