The chemical resistance of Bamboo/Glass reinforced epoxy hybrid composites to acetic acid, Nitric acid, hydrochloric acid, sodium hydroxide, ammonium hydroxide, sodium carbonate, benzene, toluene, Carbon tetrachloride and water was studied. The Tensile properties of these composites were also studied. The effect of alkali treatment of the bamboo fibers on these properties was studied. It was observed that tensile properties of the hybrid composites increase with glass fiber content. These properties found to be higher when alkali treated bamboo fibers were used in the hybrid composites. The hybrid fiber composites showed better resistance to the chemicals mentioned above. The elimination of amorphous hemi-cellulose with alkali treatment leading to higher crystallinity of the bamboo fibers with alkali treatment may be responsible for these observations.

Fiber-reinforced epoxy composites have played a principal role for a lengthy time of applications for their strength, cost-effectiveness, lightweight, and degradability. An innovative method of manufacturing rigid and robust natural fiber preforms is studied. In this connection, an investigation has been carried out to make use of Glass/Bamboo Chopped strand mat treated with bacterial cellulose. The preamble of bacterial cellulose improves the strength and stiffness of the preform. With this preform, the hierarchical composites are manufactured by using conventional composite production methods, such as resin film infusion RFI or resin transfer molding RTM. The present work describes the development and characterization of mechanical properties of Glass/Bamboo Chopped strand mat fiber-based composites consisting of reinforcement and epoxy as a matrix. Tensile, Compressive, Flexural and Impact properties are determined using Universal Testing Machine UTM.
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.

Elixir Materials Science, 2018
Polymer matrix composites (PMC) materials had acquired much attention in the field of Aeronautics over the recent decades as high strength-lightweight materials. These abundantly available fibres are embedded with a light polymer matrix resulting in a high strength and light weight fibre reinforced polymer composites. In this paper, we have investigated the mechanical behaviour of fabricated composite materials with seven different combinations consists of Bamboo/E-glass fiber as a reinforcing agents and polyester as a polymer matrix. Several tests have been carried out to enhance the properties such as tensile strength, flexural strength, hardness and impact strength and it was compared for different orientations (±30º). It is reported that the hybridization of the constituents with 20% of Glass, 10% of Bamboo shows better Tensile strength, Flexural strength and Hardness number than other combinations examined.
The Flexural, Impact properties and Scanning electron microscope analysis of Bamboo/glass fibers Reinforced polyester Hybrid composites were studied. The effect of alkali treatment of the bamboo fibers on these properties was also studied. It was observed that the Flexural, impact properties of the hybrid composite increase with glass fiber content. These properties found to be higher when alkali treated bamboo fibers were used in the hybrid composites. The elimination of amorphous hemi-cellulose with alkali treated leading to higher crystallinity of the bamboo fibers with alkali treatment may be responsible for these observations. The author investigated the interfacial bonding between Glass/Bamboo reinforced polyester composites. The effect of alkali treatment on the bonding between Glass/Bamboo composites was also studied.

It is observed that bamboo/glass fibre laminates have influenced mechanical properties.
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.
Synthesis, Testing & Characterization of Epoxy-CNT-Bamboo Polymer Matrix Hybrid Composite
The present ongoing energetic human race can't visualize its progress without bringing the conception of development in composite materials. An assortment of researches is occurring in this field to achieve the desired standard. Natural fiber reinforced polymer composite has a vast resemblance to substitute the composite made up of synthetic fiber. This is principally because of the several benefits of composites like light weight, in-toxic, in-abrasive, ease of use, low expenditure, and eco-friendly properties. The synthetic fibers have superior end of mechanical properties like tensile modulus & tensile strength nevertheless the specific mechanical properties like specific tensile modulus and other specific properties (properties/specific gravity) of natural fibers give a pleasing outcome for composites comparing to synthetic fiber based composites. The aim of the present study is to examine the mechanical attributes of bamboo fiber & CNT reinforced epoxy based composites. Bamboo fibers with varying percentage of CNT are reinforced in epoxy resin to manufacture composite materials. The outcome of bamboo fiber and CNT content on the mechanical behavior of composites has been studied.
