Sisal and Bamboo fibers are the most common fibers extracted from natural plants used to fabricate the bio-composite, environmentally friendly products. In this work, the Bamboo-Sisal fibers reinforced epoxy hybrid composite is fabricated to investigate and analyze the compression and hardness properties. The fibers were extracted mechanically and manually from bamboo and sisal plants. The 5% and 8% concentration of sodium hydroxide have been used to treat bamboo and sisal fibers respectively to eliminate lignin, cellulose, and other dirty particles in order to increase interfacial bonding of epoxy to fibers, and performance of the composite. Taguchi experimental approach is used to design composite by considering basic parameters such as weight fraction of sisal, fibers orientation, and curing temperature which affect composite performance. Compression molding and hand lay-up techniques have been used to fabricate the composite. The compression and hardness tests ware predicted on the specimen of hybrid bamboo/sisal fiber reinforced epoxy composites prepared with ASTM standard. The analyzed result revealed that the composite contains a 20/15% volume fraction of sisal to bamboo fibers and fabricated with fiber plies orientation of [0 S /0 B /0 S /0 B /0 S /0 B ] and curing temperature at 40ºC record a high compression strength. While the better hardness strength obtained from composite contain 15/20% volume fraction of sisal to bamboo fibers, and fabricated with fiber plies orientation of [0 S /0 B /0 S /0 B /0 S /0 B ] and cured at 55ºC.

Today’s modern, dynamic world would be impossible to imagine without the concept of composite material advancement. Various studies are being conducted in this area in order to reach the desired level. In terms of compatibility, natural fibre reinforced polymer-based composites and synthetic fibre composites are very similar. Because they are lightweight, nontoxic, and nonabrasive, they are very popular with consumers. They are also readily available and affordable. Composite materials made from natural fibre have superior mechanical properties compared to those made from synthetic fibre. As part of this research, an epoxy-based composite with bamboo and sisal fibre reinforcement is examined. Reinforced with epoxy resin, bamboo fibre and sisal fibre are used to make composite materials. The effect of adding bamboo fibre and sisal fibre in various weight percentages on the mechanical behaviour of composites is investigated.

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.

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.
Experimental Analysis of Bamboo and E-Glass Fiber Reinforced Epoxy Hybrid Composite
Journal of Materials Science and Engineering B, 2016
The main objective of this research is to investigate the performance of bamboo and E-glass fiber reinforced epoxy hybrid composite (BEGRC) for various applications. Initially, manual bamboo fiber extraction method was applied on Ethiopian highland bamboo species "Yushania Alpina" and soaked in a 5% NaOH to remove lignin and hemicellulose from fibers. Next, the bamboo and E-glass fiber test specimen was fabricated with 45% total fiber volume fraction and tensile, compressive, in-plane shear and flexural tests were carried out using universal testing machine. In the case of bamboo to E-glass fiber ratio of 50 : 50, it has high elastic modulus and better compressive strength. Therefore, it is clear that that bamboo and E-glass reinforced epoxy hybrid composite can be applied to various systems that require light weight and high strength.

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.

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...
