Over past few decades composite materials, ceramics and plastics have been leading emerging materials. The applications of composite material and the area in which they are being used is growing day by day. The curiosity has gained substantially towards the use of natural fibres in composites in recent few decades. Natural fibre composites are eco-friendly and often used in engineering application such as in construction, automobile, aerospace and household applications. Nano fibres are responsible for a connection between the Nano scale and the macro scale, since their diameters are in the nanometre range and the length is continuous. Nanofibre are attracting very high interest due to their extraordinary micro and Nano structural characteristics, high porosity, mechanical strength, Flexibility and integrally large total surface area. There is increased curiosity about natural fibre based epoxy composites properties to short out engineering necessities. Hence, a matter of concern to overview and check the exiting position and put efforts for sustainable and possible commercial exploitation and additional improvements. This research work shows comparison of strengths with and without added Nano fibres to the Banana fibres composite. Testing data clearly indicates the enhancement in mechanical properties when Nano fibres are added in to Natural fibre reinforced composite..

Process optimization is the key task of any engineering application to maximize the desirable output by optimizing the range of process parameters. In this research work, jute composites were fabricated by the hand lay-up method with the aim of optimizing the process parameter such as yarn linear density, fabric areal density and fabric laying angle on the mechanical properties of the textile composite structures using the Taguchi L9 orthogonal matrix. The plain-woven and twill-woven fabrics of Jute fabrics were produced through specialized handloom machine and used as preform for composite production. Epoxy resin was used as the matrix component. Signal-to-noise ratio ratio, analysis of variance and experimental verification of results were analysed. The results showed that fabric laying angle played major role to achieve high mechanical properties of composites and twill-woven structural reinforcement yields higher mechanical properties. Subsequent to this optimal process, parameters have been arrived for all the composites, and finally it was verified through the experimental results.

Machining Operations

Natural fibre composites have received worldwide attention due to their good mechanical properties, lightweight and low density. Due to these advantages, the natural fibre composites have been used in various engineering applications. Drilling is one of the most frequent machining operations performed on hybrid sisal–jute polymer composites, to assemble the numerous structural components by using mechanical joining process. Furthermore, the machining of fibre reinforced composite material has attracted several researchers because of its non-homogeneous and anisotropic structure. The present research work concerns with the experimental studies on the drilling process of hybrid sisal–jute epoxy composite, using three different types of drill geometry (twist drill, step drill and core drill). The significance of the current work aims to reveal the effect of drill geometry configuration and drilling parameters in terms of drilling-induced force and damages (delamination and surface roughness) for the drilling of hybrid natural fibre composites. Drilling forces, drilling-induced damages and hole quality attributes were experimentally investigated for different drill geometries. The delamination and surface roughness type damages are revealed by microscopic analysis with the help of scanning electron microscope (SEM). The results show that twist drill is best suited for the hole- and force-induced damages.

Load Carrying

The natural fibre reinforced composites have the advantage of being light weight, renewable, cheap and eco–friendly when compared to the synthetic fibres. So, there is a need to investigate potentiality of natural fibre which can be used in highly demanding situations. An attempt has been made in the present work to explore the possible uses of variety of cultivated and wild grown fibres in nature that aids in the development of new composites for load carrying structures. The present research work has been carried out to make use of okra /sisal natural fibres. The aim of this paper is to describe the experimental development and characterization of new set of hybrid natural fibre composites which is made by reinforcing okra /sisal fibres with polyester resin in matrix by using hand layup method. The natural fibres were extracted by retting and combing process manually. The hybrid composites were prepared using okra/sisal fibres of 30/70, 50/50, 70/30 fibre weight ratios, when subjected to varying weights of fibres (0. 4, 0. 8, 1. 2, 1. 6, 2) grams. The tensileand impact properties were carried out using hybrid composite specimens.

This paper presents the investigation of casted natural fiber-LM6 composites for engineering application. The objective of this research is to study the feasibility of natural fibre to introduce in the metal matrix composites for sand casting process. LM6 is the core material used in this research while natural fibre used as composite materials as well as to remain the hardness of the materials. The preparation of natural fibre composites was proposed to introduce in metal matrix composite material. Empty Fruit Bunch (EFB) and kenaf fibre were used in the experimental work. Natural fibre is reinforced in the LM6 material by using metal casting process with open mould technique. LM6 material was melted using induction furnace which required 650°C for melting point. The structure and composition of the composite materials is determined using EDX (Energy Dispersive X-ray) to show that fibres are absent on the surface of LM6. The microstructure of casted natural fibre-LM6 composites was presented using Zeiss Scanning Electron Microscope (SEM) with an accelerating voltage of 15kV. As a result, natural fibre composites were feasible to be introduced in metal matrix composites and potential for engineering application.

Fabrication And Characterization

Bhimal fibres are quite a newer kind of bio-degradable fibres. They have never been heard before in literatures from the view point of their utility as engineering material. These fibres have been utilized for investigation of their properties. Characterization of this fibre is essential to determine its properties for further use as reinforcing fibre in polymeric, bio-degradable and other kinds of matrix. With this objective, the fabrication method and other mechanical properties of Bhimal-reinforced-PVA biocomposite have been discussed. The stress-strain curves and load-deflection characteristics are obtained. The tensile, compressive, flexure and impact strengths have been calculated. The results are shown in tables and graphs. The results obtained are compared with other existing natural fibre biocomposites. From the observations, it has been concluded that the tensile strength of Bhimal-reinforced-PVA biocomposite is higher than other natural fibre composites. Hence these can be used as reinforcement to produce much lighter weight biocomposites.

AbstractNatural fibre-reinforced composites have attracted a great deal of attention by the automotive industry mainly due to their sustainable characteristics and low cost. The use of sustainable composites is expected to continuously increase in this area as the cost and weight of vehicles could be partially reduced by replacing glass fibre composites and aluminium with natural fibre composites. Adhesive bonding is the preferred joining method for composites and is increasingly used in the automotive industry. However, the literature on natural fibre reinforced polymer composite adhesive joints is scarce and needs further investigation. The main objective of this study was to investigate experimentally adhesively bonded joints made of natural, synthetic and interlaminar hybrid fibre-reinforced polymer composites. The effect of the number of the interlaminar synthetic layers required in order to match the bonded joint efficiency of a fully synthetic GFRP bonded joint was studied. It was found that the failure load of the hybrid jute/glass adherend joints increased by increasing the number of external synthetic layers (i.e. the failure load of hybrid 3-layer joint increased by 28.6% compared to hybrid 2-layer joint) and reached the pure synthetic adherends joints efficiency due to the optimum compromise between the adherend material property (i.e. stiffness and strength) and a diminished bondline peel stress state.
