Abstract

Objectives: The aim of this research is to design and analysis of natural fibre mechanical seal using hybrid of Agave sisalana fibre and natural rubber as reiforcement and bio epoxy resin as matrix material. Methods/Analysis: The fabrication of the mechanical seal will involve internal mixing which is to mix up the waste tires with the Agave sisalana and hot pressing is to press or sinter the material into mechanical seal. The testing involved in this project is Tensile Test, Hardness Test, Absorption Test and last is Thickness Swelling Test. The result and data collected will be analysing by using graphs. Apart from that, ANSYS has been used to providing solid modelling and analysis on mechanical seal and mould. Findings: Fibre exhibits a very good reinforcement by increasing the mechanical properties in polymer but at certain amount it can change the properties of the composites. The best composition is 85% natural rubber+5% Agave sisalana fibre+10% Bio Epoxy Resin. Application/Improvement: With the growth of the industrial sector, mechanical seal will become one of the most important things in the piping industrial. By converting natural rubber into mechanical seal, it gives advantages to both parties. Embedding with Agave sisalana increases the mechanical strength of the natural rubber material.

Abstract

Aim: The main objective of this work is to fabricate the biocomposites exploitation natural fibres like Sisal, Banana, hibiscus, Sisal and banana (hybrid), banana and hibiscus (hybrid) and sisal and hibiscus and sisal (hybrid) with epoxy (bio) glue as a reinforcement exploitation molding methodology. Methods/Analysis: In the present study, the optimum combination of fibre and organic compound is achieved by exploitation Taguchi methodology. During this work, flexural rigidity of Sisal and banana (hybrid) at a quantitative relation of 1:1, banana and hibiscus (hybrid) at a quantitative relation of 1:1 and sisal and hibiscus (hybrid) at a quantitative relation of 1:1 composite were studied at dry and wet conditions. The main focus of the work is to predict the properties of fibre fabric of the NFRP composite and also the mathematical model of deflection of beams was developed and the values are compared and located to be in sensible agreement. The wet absorption characteristics of the fibres are vital to supply the natural fibre hybrid composite materials with the positive hybrid impact. Specimens were scanned using Scanning electron microscope. Findings: The wet composites reduce the flexural properties as the presence of wet degrades the fibre matix interface strength and it makes poor stress transfer leading to a discount on the flexural strength. Each within the hibiscus and sisal fibre composites, it was found that the elongation of fibre increasing when it is immerse in the water. The explanation can be the presence of water attack on the polyose structure expectations and allow the polyose molecules to maneuver swimmingly. Application/Improvement: The application includes the replacement material for bone joints, artificial tissues, limbs, arteries, artificial tooth and skin. So, this work can be extended to other spheres of the biomaterials by extending the work and conducting other functional properties like stress distribution and biocompatibility etc.

Abstract

Objectives: In this analysis, natural fibers like, Jute, Kenaf and hemp; Jute and Hemp (mixture) Hemp and Kenaf (mixture), Jute and Kenaf (mixture) are invented with bio epoxy stick abuse forming system. This work, affects quality of Hemp and Kenaf (mixture), Jute and Kenaf (mixture) and Jute and Hemp (mixture) composite at dry and wet conditions were examined. Affect check were directed Izod affect testing machine and the little structure of the examples are checked by the Scanning magnifying instrument and contrast the leads with Ansys. Methods/Statistical Analysis: A synthetic check could be a subjective or quantitative strategy intended to demonstrate the presence of, measure, a substance or unit with the assistance of a chose compound specialist. The synthetic testing was performed in both sulphuric. The bits of the fiber strengthened polymer composite were initially weighed and after that drenched in the corrosive for around 24 hours. The pieces were then were made to a temperature of around 105°C and again weighed. The outcome uncovers the erosion resistance of the mixture polymer composites. Findings: Fiber-strengthened compound composites have contend a predominant parent for an extended time in an exceedingly style of uses for high particulate quality and modulus. The fabricate, utilize and expulsion of antiquated fiber-reinforced plastic, now and again made of glass, carbon or aramid fibers-reinforced thermoplastic and thermo-setting gums zone unit considered fundamentally on account of ecological issues. By characteristic fiber composites we tend to mean a material that is reinforced with strands, particles or platelets from regular or renewable assets, in refinement to for instance carbon or aramide filaments that should be integrated. The aftereffect of strands on effect quality for the examples prepared for each dry and wetness conditions. This check are regularly utilized as quick and basic inner control look at to work if a texture meets particular effect properties or to match materials for general sturdiness. Application/Improvements: Mixture fiber composites show halfway weak nature of break in view of the nearness of hemp strands. So by examining the protective cap display, and Experimental Results, it’s demonstrated that common fiber supported stuff of jute and hemp Hybrid material elements a property quality for the apparatus of Motor cycle Safety head protectors.
