Over the years, application of composite materials has got wider. So there is a necessity for development of new materials to satisfy the environmental requirements. It is viable through the process of hybridization of natural fibers to synthetic fibers. This investigation is carried out to determine the tensile and flexural strength of hybrid composites with various fiber combinations and stacking sequence. Thus it is easy to identify the natural fiber hybrid combination with high mechanical properties under static and varying thermal load conditions. The various fiber materials are meticulously chosen and three conventional and six different hybrid laminates were fabricated with various stacking sequences of selected fibers using hand layup technique. The tensile and flexural properties are determined through mechanical testing and compared with conventional materials. The failure morphologies are captured and investigated with zoom optical cameras. On analyzing the results, it is observed that carbon-flax hybrid composites exhibit nearly equivalent specific strength at a reduced cost compared to the carbon/glass fiber hybrid composites and also the effect of the stacking sequence in mechanical properties is elucidated through this study. Varying thermal load analysis reveals that there is a considerable loss in mechanical properties due to thermal exposure.

Fiber Reinforced Polymer Composites

Natural fiber reinforced polymer composites became more attractive due to their light weight, high specific strength, biodegradability. However, some limitations e.g. low modulus, poor moisture resistance were reported. The mechanical properties of natural fiber reinforced composites can be improved by hybridization with synthetic fibers such as glass fiber. In this research, mechanical properties of short sisal-PP composites and short sisal/glass fiber hybrid composites were studied. Polypropylene grafted with maleic anhydride (PP-g-MA) was used as a compatibilizer to enhance the compatibility between the fibers and polypropylene. Effect of weight ratio of sisal and glass fiber at 30 % by weight on the mechanical properties of the composites was investigated. Morphology of fracture surface of each composite was also observed.

Usage of Natural Fiber Composites (NFC) is increased rapidly due to the bio degradability nature of the fibers. These natural fibers are mixed with synthetic fibers to obtain better mechanical properties. In this study, pine apple and glass fiber reinforced epoxy composites are developed and their mechanical properties were evaluated. Composites were prepared by varying the fibers content and by using hand layup process with glass moulds of size 160 x 160 x 3 mm3 . The obtained laminates were sliced as per the ASTM criterion to test the properties. Higher glass fiber content in the composite specimen obtained higher mechanical properties. The composites can be utilized for the purpose of manufacturing components like doors panels, desks, roof tops etc.

This paper is a review on mechanical characteristics of natural fibers reinforced elastomers (both thermoplastics and thermosets). Increasing environmental concerns and reduction of petroleum resources attracts researchers attention to new green eco-friendly materials. To solve these environmental related issues, cellulosic fibers are used as reinforcement in composite materials. These days natural fibers are at the center of attention as a replacement for synthetic fibers like glass, carbon, and aramid fibers due to their low cost, satisfactory mechanical properties, high specific strength, renewable resources usage and biodegradability. The hydrophilic property of natural fibers decreases their compatibility with the elastomeric matrix during composite fabrication leading to the poor fiber-matrix adhesion. This causes low mechanical properties which is one of the disadvantages of green composites. Many researches have been done modifying fiber surface to enhance interfacial adhesion between filler particles and elastomeric matrix, as well as their dispersion in the matrix, which can significantly affect mechanical properties of the composites. Different chemical and physical treatments are applied to improve fiber/matrix interlocking.

The need of natural fiber-reinforced composites is increasing at very fast rate because of their ecofriendly production, decomposition, high specific strength, abundance, good physical and mechanical properties. Available literature reveals that past researchers have done a lot of work for the preparation and characterization of fiber-reinforced composites. While developing natural fiber composites, researchers encountered various problems like hydrophilic nature of natural fibers, incompatibility of natural fibers with matrix materials, thermal instability of natural fibers, and poor interfacial bonding between reinforcing phase and matrix phase. However, some of these problems can be solved to a greater extent by considering surface treatment of natural fibers before they are used in the preparation of fiber-reinforced composites. Thus, there is a need for understanding the effect of several surface treatments on the mechanical properties of fiber-reinforced composites. The aim of this paper is to put forth a comprehensive review on the effects of different surface treatments on the mechanical properties such as tensile strength, flexural strength, and impact strength and also interfacial shear strength of the fiber-reinforced composites.

Set Up

Natural fibers are excellent substitute materials for man made fibers in making fiber reinforced composites due to their high specific strength and modulus, low density, low price, easy availability in some countries, recyclable and degradable properties. They have raised great attentions among material scientists and engineers in the past decade. Many researches have been conducted to study the mechanical properties, especially interfacial properties of natural fiber reinforced composites. However, the properties, such as mechanical performances, moisture absorption behaviors, et. al of natural fibers themselves have been seldom investigated. Knowing the relationship between microstructures and properties of natural fibers are important for understanding the bulk properties of natural fiber composites and also good instructions for designing bio-mimic materials. In this study, four kinds of natural fibers which were extracted from different plant sources were investigated. The microstructures of these natural fibers were revealed with the aid of optical microscopy. Microstructure models were thereof set up and mechanical properties for the representative volume element were assumed. Fiber bundle fracture models together with probability statistics analysis were employed to calculate the mechanical properties of natural fibers. The results were compared with the experimental measurements. Different mechanical behaviors of natural fibers which were functioned differently in the nature were clearly explained by the above studies

Natural fiber-reinforced composites are necessary to increase the use of polymer composite technology. This study investigates a specific type of bamboo species named Gigantochloa Scortechinii (Buluh Semantan), collected from the Bukit Larang Village in Melaka, Malaysia. Bamboo strips with average dimensions of 300 mm x 5 mm x 0.5 mm were weaved in plain-woven bamboo and divided into 2 to 6 laminate layers through 6 layers of E-glass epoxy subjected to the hand lay-up process to produce the hybrid composite. The hybrid composites were prepared in a stacking sequence of plain-woven bamboo and were characterized in their mechanical properties. The behaviors of the tensile strength, tensile modulus, flexural strength, flexural modulus, and impact strength improved in the 2-layer laminated hybrid sequences. Still, the opposite trend was observed for the hardness value with the 6-layer laminated mixed sequences. The morphology scanning electron microscopy (SEM) results supported the findings of the mechanical properties, which demonstrated the interaction between the EP and fibers with the selected stacking sequence. The works give sound basis decisions to engineers to apply the Bamboo laminated composites in construction materials and building decoration.

Nowadays the position of natural fibers in the world fiber is stable, growing in the area of their application, not only in textiles but also in more eco-friendly composites. This work is focused on study of the effect of  SiC as filler material on the banana peduncle/Carbon fibers reinforced hybrid composites. Four different laminates are fabricated by varying the matrix composition (BP, BP+SiC, carbon+BP, Carbon+BP+SiC ). The alkaline treatment with 6% NaoH of the BP fibers improves the specific strength and binding properties. The filler added composites laminates shows higher mechanical properties. From the results, it is seen that mechanical properties like Tensile, Flexural, ILSS, Impact and hardness are improved by 89, 75, 99, 68 and 64% by the addition of the SiC to the banana peduncle/Carbon fiber composite laminate.

AbstractNowadays, natural fiber reinforced polymer composites are widely used because of their advantageous properties like minimum density, maximum specific strength, low cost and easy availability. Manufacturing of natural fiber composite is easy as compared to the conventional methods. In the present scenario, due to an increasing interest in environmental consciousness with greenhouse effect, various industries have initiated the use of eco-friendly materials and are replacing hazardous materials with such eco-friendly materials. The present work aims to determine the tensile strength of okra and jute fibers reinforced in Epoxy LY-556 and XIN-100IN Resins. Okra fibers are developed from the stem of the plant of the Malvaceae family. Their use as reinforcement in polymer composites requires the basic knowledge of their mechanical properties. Jute fibers are developed from the best jute plants. The conclusions are based on their mechanical properties and behavior.

Economic and environmental concerns lead the researchers toward development of sustainable and renewable materials of which reinforced composites are part of. The abundantly available natural fibers have attracted the researchers to study their performance as reinforcements and feasibility for making automobile components. The performance of composite materials is mainly assessed through their mechanical properties. However, natural fibers to date were mainly used as reinforcements to create bulk composite components with reduced cost rather than improved mechanical performances. Among the methods available for improving mechanical properties of the natural fiber composites, combined mercerization treatment, hybridization, and incorporation of fly ash fillers in the matrix are the best solutions. Therefore, the objective of this research is to evaluate the tensile properties of hybrid kenaf/glass composites with and without fly ash particulate filler as per ASTM standards. Moisture absorption behavior and its effect on the tensile properties of hybrid composites are also investigated. The results revealed that the addition of 10wt % fly ash particles with natural fiber composites increased the tensile strength of composites while hybridization with glass fibers reduced the water absorption properties.
