Now-a-days the composite materials have been replaced the traditional materials. The attractive features of natural fibers like jute, Sisal, coir, bagasse and banana have been their low cost, high tensile strength, low thermal expansion, high strength to weight ratio, renewability and biodegradability. This present experimental study aims at learning the Development action of hybrid natural fiber reinforcement polymer composite material such as sisal and sugarcane bagasse fibers with epoxy resin(ER) as a matrix in automobile applications. The test specimens have to be prepared as per ASTM Standard by changing volume fraction (0, 30, 40, 50, and 60%). The specimens are tested experimentally for mechanical properties such as tensile, Rockwell hardness and water absorption.

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...

Use of natural fibers as reinforcement have gained the importance in the recent years due to the eco-friendly nature. These natural fibers offer a number of advantages over traditional synthetic fibers. This paper deals with the evaluation of mechanical properties namely, Tensile strength (TS), Flexural strength (FS), Vickers Hardness (Hv), Impact Strength (J). Specimens were prepared by hand lay-up technique and are cut as per ASTM standards to perform test. In the present work experimental investigation has been carried out on different weight percentage of bamboo fiber (0, 15, 30 and 45) is used to modify epoxy resin properties. The experimental result reveals that the mechanical properties of the composite material were highly influenced by the fiber volume fraction (fiber loading). Addition of alumina (Al2O3) particulate at various proportions as filler material the mechanical properties viz. Tensile strength, Flexural strength, Hardness, Impact strength are improved.

Hybrid polymer composite were prepared by incorporating two indigenous agro-industrial waste reinforcements, sugarcane bagasse fiber (SBF) and coconut coir fiber (CCF) into epoxy resin through the hand lay-up technique. Nano-silica was also added to enhance the mechanical performance of composite materials. The alkaline treatment on the surface of natural fibers was carried out and its effects on the mechanical properties were investigated. Generally, it is found that the CCF reinforced epoxy composites exhibited higher mechanical properties as compared to the SBF reinforced epoxy composites. For hybrid composite samples, (2.5wt%SBF+12.5wt%CCF) had attained the highest mechanical performance amongst all other different ratio percentage of hybrid polymer composite.

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 Testing of Natural Fiber Hybrid Composites
Inthe growing environmental awareness bio-fiber reinforced plastic composite has received increasing attention during the recent years. The composites have lot of advantages over the traditional glass fiber or mineral filled ceramic materials including low cost, light weight, eco friendliness and recyclability. In this paper I use banana, bamboo and pine apple fibers. By using the above mentioned three reinforcement with epoxy resin we will be provided with combinations of banana/bamboo, pineapple/bamboo and banana/pineapple hybrid composites. By the combination of all the three fibers we get bamboo/banana/pineapple hybrid composites. The percentage of resin added is about 70% and the fiber is of 30%. The fabricated samples are subjected to mechanical and physical tests as per the ASTM standards. The best combination is suggested for the manufacturing of automobile applications.
NATURAL FIBER REINFORCED POLYMER COMPOSITES FOR AUTOMOBILE ACCESSORIES
The invention is an effort to utilize the advantages offered by renewable resources for the development of composite materials based on polymer and particles of natural fibers for Conservation of natural resources. In this research, natural fibers like Sisal (Agave sisalana), Banana (Musa sepientum) and Roselle (Hibiscus sabdariffa), Sisal and banana (hybrid), Roselle and banana (hybrid) and Roselle and sisal (hybrid) are fabricated with bio epoxy resin using molding method. The applications of these materials require a sustainable approach to creating green products. Green materials are very important to form environment friendly from renewable resources and decrease the use of petroleum based chemicals. Nowadays natural fibers form an interesting alternative for the most widely applied fibre in the composite technology, glass. The use of fibers like sisal, Roselle and banana in this industry so far is small since availability of a durable semi-finished product with constant quality is often a problem. Recent research and development have shown that these aspects can be improved considerably. Knowing that natural fibers are cheap and have a better stiffness per weight than glass, which results in lighter components, the grown interest in natural fibers is clear. Secondly, the environmental impact is smaller since the natural fibre can be thermally recycled and fibers come from a renewable resource. Their moderate mechanical properties restrain the fibers from using them in high-tech applications, but for many reasons they can compete with glass fibers. In this paper the optimum mixing of fiber and resin is achieved by using Taguchi method. In this work, tensile and hardness of Sisal and banana (hybrid), Roselle and banana (hybrid and Roselle and sisal (hybrid) composite at dry and wet conditions were studied. Hardness test were conducted using Brinell hardness testing machine. In this work micro structure of the specimens are scanned by the Scanning Electron Microscope. The disclosure includes the process to make the composite and also the variety of products in automobile accessories.

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.
