The use of Gasket or sealing ring is one of the most important and just less than a perfect method to prevent leakage of fluids both during the static and dynamic condition. Moreover, the subject of using natural or organic materials has gained prime importance amongst both designers and researchers to reduce environmental impact. This study focuses on the design and Analysis of gasket material which has a combination of Latex and Natural Fibres. Significant areas where gaskets are used have thermal and pressure force as a boundary condition, which demands the need for various sealing ring material. The model of Gaskets is prepared as per standards in SOLIDWORKS 2016 Comparison based on equivalent stress, deformation, thermal expansion, thermal stress and strain are done between Silicon rubber and natural composite materials in ANSYS workbench 18.2. The model was analysed between three materials which are Silicon rubber, Latex and Banana fibres, Latex and Coconut coir. Mathematical interpolation is used to obtain various mechanical properties of the natural Fibre using volume fraction. The critical properties considered for the Analysis are young’s modulus, the thermal expansion coefficient of the Natural Fibres

Non-contact processing technique involving the use of CW and pulsed CO2 laser irradiation has been used for reducing the core loss of cold-rolled grain-oriented silicon steel. Laser scribing perpendicular to the rolling direction resulted in a refinement of domain wall spacing which subsequently reduced the loss of silicon steel. It was found that laser irradiation was more effective in a specimen with higher magnetic induction (Hi-B) and the loss was reduced by more than 10% under optimum conditions of the laser irradiation and the scribing speed. Since laser processing is a non-contact technique, it can be easily applied to the production line of the silicon steel.
