Various analysis has been completed everywhere the world for creating completely different reasonably natural fibres As a strengthening substance for the preparation of the varied varieties of composites. The material is typically composed of two elements, i.e. matrix and filler chemical therapies in the manner of fibre will clean Stop the absorption of wetness by the fibre surface, with chemicals Modify and raise the surface of the mechanical properties. These studies square measure targeted on developing composition and characterization of mechanical, rheological and structural analysis of obtained composites with completely different plant fillers. Variation of the natural part superimposed in fibre material and analyse its mechanical behaviour to get the best style of fibre. These applications square measure principally their strong ratio-to-weight strength magnitude relation, high durability High temperatures, elevated creep resistance and high intensity. Testing of mechanical properties tensile, flexural, impact and hardness has been administered. The experimental result provided shows decent mechanical behaviour. it absolutely was found that the mechanical properties were improved by the natural additive material.

The world has witnessed a standstill moment because of outbreak of coronavirus not sparing anyone across ethnicity, be it rich or poor, black or white, east or west, north or south. The pandemic has affected various sectors, education being one of it. According to UNESCO, close to 900 million learners have been affected by the closure of educational institutions. (11) Due to this pandemic, the educational institutions have to move from conventional mode of parting education to online mode. The research paper highlights advantages and disadvantages of imparting education through online mode during the pandemic situation.

Aluminium alloy was a predominant metal among alloys elements. The aluminum alloys like Al7075 and Al6061 which has the major elements of Zn, Mg, Cu, Si with which it will improve the hard-brittle crystalline structure and conductivity. To enhance the properties of dissimilar joint metal, TIG (Tungsten Inert Gas) welding is propagated. Mechanical properties like Tensile, Impact, Bending, micro-hardness and the study about microstructure analysis were carried out. As a result, the energy absorbed by the dissimilar joint metal is 16J and the hardness of dissimilar joint metal is 51.3HV.It revealed that, there is a high impact strength and micro-hardness properties. Consequently, the microstructure (HAZ) image exhibits good bonding strength and sufficient plastic deformation was improved due to fine distribution of grains.
