The modern, dynamic world can't imagine its development without carrying the concept of advancement in composite materials. Various researches are going on in this field to achieve the desired standard. Natural fiber reinforced polymer composite (NFPC) has a huge affinity to interchange the composite made up of synthetic fiber. This is primarily because of the advantages like lightweight , non-toxic, nonabrasive, easy availability, low cost and biodegradable properties. The specific mechanical properties like specific tensile modulus and other specific properties of natural fiber gives a satisfying result for composites as compared to synthetic fiber based composites. The objective of article is to investigate the mechanical behaviour of short treated and untreated bamboo fiber reinforced epoxy based composites. Bamboo fibres with different length and contents are reinforced with epoxy resin to fabricate composite materials. The effect of fiber length and content on the mechanical behaviour of composites is studied.
COMPOSITE MATERIAL USING BAMBOO FIBER WITH EPOXY RESIN
The high cost of synthetic fibers such as glass, carbon, kevars etc, results in high cost of production and products derived from these materials which has necessitated alternative means of materials development. This has also informed the utilization of locally available bamboo fiber for composite materials development. Natural fiber has emerged as a renewable and cheaper substitute to synthetic materials such as glass, carbon and afraid, which are used as reinforcements. In this work, the objective was to develop, investigate and analyze the mechanical properties of a composite material using bamboo fiber polymer. The long bamboo fiber was extracted using chemical digestion and maceration methods. The fabrication of the composite was carried out using epoxy resin as the matrix and the bamboo fiber as reinforcement. Tests were carried out to determine the mechanical properties such as tensile, hardness and compressive strengths. The results were studied and compared with the conventional materials and it process that the material developed can be used in structural applications with strong dependence on its mechanical properties.
Fabrication and Study of Mechanical Properties of Bamboo Fibre Reinforced Bio-Composites
In the present work experimental investigation has been carried out to study the effect of bamboo fibres at different weight percentages (20, 30 and 40) to modify epoxy resin. Tests are conducted on 100 kN servo-hydraulic universal testing machine under displacement mode of control, digital Rockwell hardness testing machine and impact testing machine. Modifying epoxy resin through bamboo fibres and improve mechanical properties is main focus of this study. Bamboo fibres at different wt% (20, 30 and 40) are filled in epoxy resin and the effects of mixing bamboo fibres on mechanical and physical properties are studied. On the basis of mechanical testing results it is found that 30 wt% of bamboo fibre mixed epoxy is giving optimum mechanical properties. The addition of bamboo fibres has improved tensile, flexural and impact properties of epoxy resin and increased water absorption of the material. On the basis of overall study the epoxy modified with 30% of bamboo fibre is found to be better than other combinations.

Bamboo and Sisal fibers are among the most common used reinforcement materials in the fabrication of new natural fiber based composite materials. In this work, an attempt is made to fabricate, characterize and analyze the mechanical property of hybrid sisal/bamboo fibers reinforced epoxy matrix composite. The fibers were manually extracted from sisal and bamboo plants. After extraction, bamboo and sisal fibers were chemically treated with 8% and 5% sodium hydroxide respectively, to remove the extra lignin and hemicelluloses so that the bond and interfacial, shear strength of the fibres can be improved. The experiment was conducted based on Taguchi experimental method by considering weight fraction of hybrid sisal/bamboo fibers, fibers orientation and curing temperature as basic parameters which affect product strength. Hand lay-up and compression techniques were employed in the fabrication of the experimental composite. The tensile and flexural strength tests of the experimental hyb...

Natural fiber application due to its competitiveness attracted many research in green composites. However, the tensile properties of natural fiber composites might be influenced by several factors such as treatment of the fibers, manufacturing processes, and water absorption levels. In this research, we use petung bamboo fibers as natural fibers candidate for a good reinforcement in green composites. The study focused on the tensile property of bamboo fiber reinforced epoxy composites due to alkali treatment, manufacturing process, and water absorption. The composites were made with three variations: the fibers were varied without and with alkaline treatment (5% NaOH); manual lay-up method and hot press were applied as manufacturing variation; moisture content in the composites was varied in dry condition and after water absorption treatment. Tensile testing and Scanning Electron Microscope (SEM), were performed to improve tensile strength of composite and fiber-matrix interface quality. The alkali treatment has less effect to the tensile strength than of the volume fraction gain and the void content. Composite manufacturing by hot press has a significant effect to the improvement of tensile strength up to 37% compare to the hand lay-up method. Water absorption up to 8.8% had decreased the tensile strength of composites up to 29%. The alkali treatment on the bamboo fibers had effectively reduced water absorption into the composite as well as the tensile strength reduction.
Tensile Behaviour of Chemical Treatment for Bamboo Epoxy Composites
Chemical Engineering Transactions, 2018
Previous studies proved that mechanical properties of natural fibres reinforced polymer composites are excellent and competent to be utilised in high-tech applications. In contrast, the presence of chemical constituents such as cellulose, lignin, hemicellulose and wax substances in natural fibres preventing them from firmly bind with the polymeric resin and thus, resulted in poor mechanical properties of composites. To overcome this defect, modification of fibre surface was done by chemical treatment. In this study, the effect of 1 %, 2 % and 3 % concentration of sodium hydroxide solution on tensile behaviour of the bamboo reinforced epoxy composite was studied. The result showed that treatment with highest studied concentration significantly influenced the tensile properties of the composite. Thus, indicates that the treatment has done excellent work in modifying the surface of bamboo fibre for better adhesion with epoxy matrix.

The present study focused to improve material characteristics and quality in terms of the NaOH concentration for treating the coconut and bamboo fiber to enhance the mechanical properties of natural fiber polymer-based hybrid composites. The NaOH-treated fibers were washed thoroughly using distilled water and allowed to dry for 24 hours. Composition of each specimen, bamboo (B) and coconut (C) fiber with epoxy composite, was prepared by hand layup process as per the American Society for Testing and Materials (ASTM) standard. The proportionality of the material was carefully fulfilled according to the previous literature reports. The weight fraction of the composite material content was set to be 30% and 70% of epoxy (E) resin and isolated fibers. Three distinct criteria were used to calculate mechanical parameters such as tensile strength, flexural strength, and material hardness. It was found that the combination of 70% E with 30% BC of hybridized composite had a maximum tensile st...

Evaluation of Mechanical Properties of Polymer-Composite Reinforced with Nigerian Long Bamboo Fibres
Bamboo reinforced epoxy have adequate properties to attract its use as structural material in engineering applications. Research materials on bamboo-plastics composites are not common. This work is an experimental study of bamboo-epoxy composite on which mechanical properties were evaluated. The long bamboo fibres were extracted from Bambusa vulgaris. The production of the composite was carried out using Bisphenol-A-di glycidyl ether (BADGE) as the matrix and the long bamboo fibre as reinforcement. Tests were carried out to determine the mechanical properties such as flexural strengths and hardness. The flexural strength of the reinforced composite (145.71N/mm2) is three times stronger than the non-reinforced composite. The hardness value was not significantly affected. The study indicated that the mechanical properties of bamboo-epoxy were comparable to ordinary fibre- glass reinforced plastics. Therefore, the material developed can be used in structural applications with a strong dependence on its mechanical properties.
