Composite materials are extensively used in the structural applications due to its enhanced load-bearing capabilities. Mostly, the mechanical properties of the natural fiber-reinforced hybrid composites are better than the single fiber-reinforced composites and almost equal to the synthetic fiber composites. This paper presents the extraction and preparation methodology of the isophtallic polyester composites using the naturally available fibers like snake grass, banana and coir fibers. The tensile and flexural properties of the snake grass fiber-reinforced composites are compared with the snake grass/banana and snake grass/coir fiber-reinforced hybrid composites. The stress–strain curves of the snake grass, snake grass/banana and snake grass/coir fiber composites and the fiber pull-outs in the fractured specimen are analyzed for the higher and lower mechanical properties. The result shows that the snake grass/banana and snake grass/coir fiber composites have the maximum tensile and...

Development and Study of Properties of Natural Fiber Reinforced Polyester Composites
Fiber reinforced composites offer varied advantages in various applications. Today fiber composites aeronautically used in such diverse applications as automobiles, aircraft, space vehicles, offshore structures, containers and piping, sporting goods, electronics, and appliances. In this work, Bamboo, Jute and Grass fibers reinforced with polyester composite specimen pieces are prepared separately. Their Tensile, Flexural properties are determined using Universal Testing Machine ( UTM ), Chemical resistances are studied and compared and Scanning Electron Microscope ( SEM ) analysis is carried out. It is observed that flexural strength of the reinforced composites increases with bamboo fiber content. Through SEM analysis, the interfacial bonding between bamboo, jute, grass fibers and the matrix- polyester, is studied. The chemical resistance of Bamboo, jute and grass fiber reinforced with polyester composites to acetic acid, Nitric acid, Hydrochloric acid, Sodium hydroxide, Sodium carbonate, Benzene, Toluene, Carbon tetrachloride and Water is studied. These results have demonstrated a new approach to use natural materials to enhance the mechanical performances of composites.

Natural fibers show many advantages such as low density, low cost, environment-friendly, biodegradable and high specific mechanical performance. This work investigates the flexure and impact strength of hemp and coconut short fiber which is specification aligned in a specific direction. The short fiber of hemp, munj, coconut and hybrid of length 5mm is used for experimental work with epoxy of grade LY556 and hardener HY951. Test results are compared with a randomly oriented fiber sample of the same length with the same epoxy and hardener.
Prediction of tensile properties of hybrid-natural fiber composites
Composites Part B: Engineering, 2012
The tensile strength and modulus of short, randomly oriented hybrid-natural fiber composite was found out experimentally and also predicted using Rule of Hybrid Mixture (RoHM). Hybrid composites were prepared using banana/sisal fibers of 40:0, 30:10, 20:20, 10:30, and 0:40 ratios, while overall fiber volume fraction was fixed as 0.4V f. The comparison between experimental and RoHM showed that they are in good agreement.

In present times, there is an increase attention has been made on the use of renewable resources, specially of plant origin, keeping in view the ecological concerns as well as renewability. As natural fibers are renewable resources in many developing countries of the world as they are cheaper, have no health hazards and provide a solution to environmental pollution by finding new uses for the waste materials. The mixing of reinforcements to prepare hybrid composites is attractive as it allows the designing of composites with mechanical performance to meet the need of the product. The advantage of replacing synthetic fibers for natural ones, is that they are eco friendly. Various combinations of different types of synthetic and natural fibers are used to meet design requirements in many different application. In this present study, mechanical properties the effect of untreated and alkaline treated (5% NaOH) sisal and bamboo fiber composite has been studied. The fiber length and fiber content increases in sisal and bamboo fiber composites there is an increase the mechanical properties. The alkaline treated sisal and bamboo fiber composite has showed a remarkable increase tensile, flexural and impact strength as compared to that of untreated.

Materials Today: Proceedings, 2017
The tensile strength, flexural strength and impact strength of short randomly oriented banana/Jute hybrid polyester composite were studied. The fiber volume fraction were taken as 5%, 10%, 15%, 20% and 25% maintaining the banana/jute volume in 1:1 ratio. The specimens were prepared for 3 mm and 5 mm thicknesses. Manual operating hot compression molding method was used for fabrication of composite maintaining 85 o C temperature. For tensile test, flexural test and impact test, ASTM D3039, ASTM D7264 and ASTM D256 standard respectively were followed. The optimum fiber volume fraction for tensile and flexural strength is found to 15%. Impact strength increases with the increase in fiber loading continuously up to 25%. The mechanical properties slightly increase with the increase in thickness of specimen.

A composite material is a materials system made up of two or more micro or macro elements with different forms and chemical compositions that are largely insoluble in one another. It basically comprises of two phases: matrix and fiber. Polymers, ceramics, and metals such as nylon, glass, graphite, Aluminium oxide, boron, and aluminium are examples of fibres. In the present research work epoxy is used as matrix and Bamboo, Sugarcane Bagasse and Coconut fibre are used as fibres for preparing the composites. In the preparation of specimen, the fibre as taken as a continuous fibre. The fibre is treated with NaOH solution. Hybrid natural fibre reinforced composites of bamboo, sugarcane baggase and coconut coir has been prepared using hand lay-up process of composite manufacturing. These hybrid composites were tested for determining their tensile and impact strengths. Results of mechanical testing reveals that the tensile strength of Bamboo-Bagasse hybrid composite is more compared to other composites. Taking into consideration of enhanced tensile and impact strength of bamboo-bagasse hybrid natural fibre polymer composite, we recommend the use of hybrid bamboo-bagasse composite in manufacturing of automotive bodies. Because of their unique characteristics of recyclability, waste utilization, biodegradability, good strength, and a viable alternative to plastics, these composites can be used for a variety of applications.
