The objective of this work is to realize new polymer composite material containing high amount of natural fibers as a bio-based reinforcement phase. Short banana fiber is chosen as a reinforcement material and epoxy polymer as a matrix material. About 77 wt.% of banana fibers were reinforced in the epoxy polymer matrix composite, using pressure induced fiber dipping method. Nanoclay particles were infused into the banana fibers to improve the fiber matrix interface properties. The nanoclay infused banana fiber were used to reinforce epoxy composite and its properties were compared with untreated banana fiber reinforced epoxy composite and banana fiber reinforced epoxy filled with nanoclay matrix composite. The surface characteristics of these composites were examined by electron microscope and the result shows well dispersed fibers in epoxy matrix. Thermal (thermogravimetry analysis and dynamic mechanical analysis), mechanical (tensile and fiber pullout) and water barrier properties of these composites were examined and the result showed that the nanoclay infused banana fiber reinforced epoxy composite shows better and improved properties. Improved surface finish composite was also obtained by this processing technique.

The use of natural fibers in making a variety of synthetic material has attracted attentions due to mainly two causes. 1. Making use of waste material into usable composites and 2. To tide over disposal of waste which otherwise causes degradation of environment. In the present study raw coir fiber was chemically treated with nitro compounds. It is a kind of chemical modification of fiber. Treated fiber was reinforced with epoxy polymer in the 1:1:1(resin: hardener: treated fiber). Dielectric estimation of the resulting composite was done with Wayne Kerr impedance analyzer in the temperature range of 30Oto 180OC at different frequencies. Systematic variation in properties was found from pure epoxy composite to fiber reinforced epoxy composite. XRD study reveals that composite is crystalline in nature. Change in morphology of the fiber was found when compared with untreated fiber, which is confirmed by Scanning Electron Microscopy. The objective of this study is to utilize the coir fiber, a waste product found in abundance in nature. If natural fibres could be used as reinforcement material in polymers, it may lead to new dimensions to research in the area of embedded materials. It might prove as an asset in electronic, automobile and engineering fields. It is lightweight; bio-degradability makes it a potential in new arena when India goes green.Keywords: coir, fiber, reinforcement, polymer

Indonesia is one of countries with the potential for abundant natural resources, especially natural fibers. The potential of Indonesian natural fibers abundant is not fully put to good use to increase social welfare. One of the natural fibers that have the potential to be developed is the banana fiber. Banana fiber has potential in abundance and can be developed as a biocomposite material that is strong, inexpensive, environmentally friendly, and can be recycled. This study aims to produce a tensile strength of Banana Fiber Reinforced Epoxy Composite Materials (BFRECM). Testing of the tensile strength refers to the ASTM D 3039 / D3039M. Based on the research results, obtained the tensile strength of BFRECM (62.3 ± 0.67) MPa and modulus of elasticity (8.72 ± 1.12) GPa. Tensile strength obtained will be referred for further study of natural fiber composites.

Purpose The purpose of this paper is to study the effects of fiber length and content on properties of E-glass and bamboo fiber reinforced epoxy resin matrices. Experiments are carried out as per ASTM standards to find the mechanical properties. Further, fractured surface of the specimen is subjected to morphological study. Design/methodology/approach Composite samples were prepared according to ASTM standards and were subjected to tensile and flexural loads. The fractured surfaces of the specimens were examined directly under scanning electron microscope. Findings From the experiment, it was found that the main factors that influence the properties of composite are fiber length and content. The optimum fiber length and weight ratio are 15 mm and 16 percent, respectively, for bamboo fiber/epoxy composite. Hence, the prediction of optimum fiber length and content becomes important, so that composite can be prepared with best mechanical properties. The investigation revealed the suitability of bamboo fiber as an effective reinforcement in epoxy matrix. Practical implications As bamboo fibers are biodegradable, recyclable, light weight and so on, their applications are numerous. They are widely used in automotive components, aerospace parts, sporting goods and building industry. With this scenario, the obtained result of bamboo fiber reinforced composites is not ignorable and could be of potential use, since it leads to harnessing of available natural fibers and their composites rather than synthetic fibers. Originality/value This work enlists the effect of fiber length and fiber content on tensile and flexural properties of bamboo fiber/epoxy composite, which has not been attempted so far.

Banana Fibers

A number of methods are available for characterization of the structural, physical, and chemical properties of natural fibers. Various methods are used for fiber identification like microscopic analysis, solubility, heating and burning technique density, staining etc. End-use property characterization methods often involve use of laboratory techniques which are adapted to simulate actual application as composite reinforcement. One of the techniques used on this kind of studies is the infrared spectroscopy. In fact, Fourier Transform Infrared (FTIR) spectroscopy is a valuable tool in the determination of functional groups actively interacting within a fiber. In this work, the banana fiber was evaluated by FTIR to reveal these functional groups and compare to similar works on other different types of banana fibers.

Banana Fibers

Synthetic fibers are being replaced gradually by natural materials such as lignocellulosic fibers. Compared to synthetic fibers, natural fibers have shown advantages in environmental, societal, economical and technical aspects. Thus, there is a growing worldwide interest in the use of those fibers. The banana fiber, extracted from the pseudo-stem of the plant, displays significant properties yet to be studied. Few thermal properties on banana fiber as reinforcement of epoxy matrix were fully evaluated. Therefore, the present work had as its objective to investigate, by photoacoustic spectroscopy and photothermal techniques the thermal diffusivity, specific heat capacity and thermal conductivity of epoxy composites reinforced with banana fibers .The epoxy matrix was added with up to 30% in volume of continuous and aligned banana fibers. The results indicated that these composites have good insulation capacity.
