A composite material is a materials system made up of two or more micro or macro elements with different forms and chemical compositions that are largely insoluble in one another. It basically comprises of two phases: matrix and fiber. Polymers, ceramics, and metals such as nylon, glass, graphite, Aluminium oxide, boron, and aluminium are examples of fibres. In the present research work epoxy is used as matrix and Bamboo, Sugarcane Bagasse and Coconut fibre are used as fibres for preparing the composites. In the preparation of specimen, the fibre as taken as a continuous fibre. The fibre is treated with NaOH solution. Hybrid natural fibre reinforced composites of bamboo, sugarcane baggase and coconut coir has been prepared using hand lay-up process of composite manufacturing. These hybrid composites were tested for determining their tensile and impact strengths. Results of mechanical testing reveals that the tensile strength of Bamboo-Bagasse hybrid composite is more compared to other composites. Taking into consideration of enhanced tensile and impact strength of bamboo-bagasse hybrid natural fibre polymer composite, we recommend the use of hybrid bamboo-bagasse composite in manufacturing of automotive bodies. Because of their unique characteristics of recyclability, waste utilization, biodegradability, good strength, and a viable alternative to plastics, these composites can be used for a variety of applications.

In recent years, the development of natural and synthetic fibers reinforced hybrid composites is one of the high attractive research fields. These composites are one of the major concerns for many industrial applications due to weight reduction and ecological reasons. In this experimental study, partially eco-friendly hybrid composites were fabricated by using carbon and flax fibers with epoxy resin. The composites were fabricated by hand lay-up process and the properties such as inter-laminar shear strength (ILSS), Fourier transform infra-red (FTIR) spectroscopy analysis, hardness, wear behavior and weight gain characteristics have been carried out. The internal structures of the fractured surfaces of the tested composites were analyzed using a scanning electron microscopy (SEM) analysis. From the experimental results, it is observed that the average weight loss is 17.98%, ILSS varies between 3.96 and 4.9 MPa and hardness is in the range of 62.33-77.66 (HRC). The results further revealed that the percentage of water intake of the flax fiber is 92%, carbon fiber is 36.6% and these fibers reinforced composite is 61.9%. From the results, it is concluded that the above said properties are comparable with pure carbon fiber reinforced composites, which shows the potential for hybridization of flax fiber with carbon fiber.

Flax/basalt/E-glass Fibers Reinforced Epoxy Composites with Enhanced Mechanical Properties
Journal of Natural Fibers, 2020
Mechanical properties of flax/basalt/E-glass fibers reinforced epoxy composites were studied in this paper. Vacuum bagging technique was adopted for the fabrication of hybrid composite laminates. The effects of fibers relative amounts and stacking sequence on the tensile, flexural and impact properties were investigated. Results showed that the developed hybrid composites display enhanced tensile, flexural, and impact performance as compared to flax fiber/epoxy composite. The tensile, flexural, and impact strengths increase when partial laminas from flax fiber/epoxy laminate are replaced by basalt and/or glass fiber reinforced epoxy laminas. Incorporating high strength fibers to the composite outer layers leads to improved flexural and impact resistances, whilst the opposite was noticed for tensile properties. The fabricated hybrids show economical and specific mechanical properties benefits. Fibers relative amounts and stacking sequence have noticeable effects on the studied mechanical properties.
In last few years, many new composites is being developed day by day because of their high specific mechanical strength. In this work, analysis of mechanical behavior of sisal, jute and coir fiber reinforced epoxy (LY551) composite was studied. Composite laminates by mixing sisal, jute and coir fiber and epoxy with proper curing agents by compression molding method. This was placed on the matched plate mold and pressed at 1500PSI for 24 hours at 1000C temperature. The sisal, jute and flax fiber reinforced epoxy Resin Composites manufactured at various ratios such as (15:15:5, 20:10:5& 25:5:5 (gm.)). The composite proportion ratio between fiber and resin was taken as (35:65).

Natural fibre reinforced composites of any group are essential to satisfy the current demand and to keep the environment-friendly approach. In the present work, an attempt has been made to replace glass fibres partially by cotton fabric so as to reduce weight and cost of the resultant composite Here, cotton fabric 0.4 mm thick (125 GSM) and fibreglass woven roving 0.15 mm thick (180 GSM) were used with epoxy resin in different weight fractions to prepare hybrid composites. The composites were prepared using hand lay-up method. The Tensile strength, flexural strength, impact strength and hardness tests were performed as per ASTM standards and results are reported for each sample. The specimens were characterised using scanning electron microscope (SEM). The mechanical properties of composites with 80% glass fibre and 20% cotton fabric are found to be closer to glass/epoxy composites. Hence it is concluded that 20% glass fibres can be replaced by cotton fabric in the existing glass/ep...

The effect of unidirectional (UD) carbon fibre hybridisation on the tensile properties of flax fibre epoxy composite was investigated. Composites containing different fibre ply orientations were fabricated using vacuum infusion with a symmetrical ply structure of 0/+45/−45/90/90/−45/+45/0. Tensile tests were performed to characterise the tensile performance of plain flax/epoxy, carbon/flax/epoxy, and plain carbon/epoxy composite laminates. The experimental results showed that the carbon/flax fibre hybrid system exhibited significantly improved tensile properties over plain flax fibre composites, increasing the tensile strength from 68.12 MPa for plain flax/epoxy composite to 517.66 MPa (670% increase) and tensile modulus from 4.67 GPa for flax/epoxy to 18.91 GPa (305% increase) for carbon/flax hybrid composite. The failure mechanism was characterised by examining the fractured surfaces of tensile tested specimens using environmental scanning electron microscopy (E-SEM). It was evide...
Composites consist of two different materials, one is base matrix material and another one is reinforcement material. Composites give unique properties than individual matrix material. Composites are gaining the demands in various applications because of its distinct properties such as higher tensile strength, higher fatigue strength, better impact strength, good flexural strength and better strength to weight ratio. In present paper a review is carried out on identifying the effect on mechanical properties of hybrid fibre reinforced polymer matrix composites. Present study focus on the combination of the natural/synthetic fibre mixed with each other. Hybrid polymer matrix composites show better mechanical properties than single fibre reinforced polymer matrix composites. Due to its good properties and cost effective nature hybrid polymer matrix composite are used in automotive industry, biomedical industry, air craft and aerospace industry, house hold applications etc.

Fiber reinforced composites are the new age materials, which play a major role in the service sector and engineering field. These materials are tailor-made materials with a different volume fraction of resin and fibers, and the stacking sequence could be made unique for each application depends on the strength requirement. Therefore, whenever engineers try to use a new configuration the proposed laminate has to be tested for its mechanical performance. Nevertheless, experimental testing of each new laminates is a time consuming and expensive process. In this work, comparative study on the results of the mechanical performance of glass/kenaf and glass/aloe Vera fiber reinforced epoxy composite laminates obtained using both experimental testing and Finite element Analysis Method (ANSYS 16.2) is done to find the closeness between the results from the two methods. The laminates are prepared using vacuum assisted resin transfer molding method (VARTM), and the tensile and flexural tests are carried out based on ASTM standard. The comparison of the experimental and FEA method shows that the variation in results is only between 8 to 3%, in two types of laminates, proving that the Finite element method is equally effective, less time consuming and economical for composite analysis.
