Monotonic (tensile and compression) properties of woven kenaf/glass reinforced unsaturated polyester sandwich hybrid composites have been experimentally investigated. Five types of composites laminates were fabricated using a combination of hand lay-up and cold press techniques, postcured for two hours at 80°C and left for 48 hours at room temperature. The hybrid composites contained fixed six layers of glass as a shell, three on each side, whereas the number of core kenaf layers was changed in three stages to get S1, S2, and S3 hybrid composites. Composites specimens with pure glass and kenaf were also fabricated for comparison. It was found that one kenaf layer replaced about 20% of total fiber weight fraction of the composite; this leads to reducing the density of final hybrid composite by 13%. Besides, in mechanical properties perspective, there are less than 1% reduction in compression strength and 40% in tensile strength when compared to pure glass composite. Generally, the results revealed that the best performance was observed in S1, which showed a good balance of all mechanical properties determined in this work.

The aim of the present work is to develop novel hybrid composites using areca, kenaf, and snake grass fibers as reinforcement and epoxy as the matrix. The areca, kenaf, and snake grass fibers were extracted from Catechu Linnaeus, Hibiscus cannabinus, and Sansevieria Ehrenbergii plants, respectively, and treated with 5% NaOH to improve the interfacial adhesion between the hydrophilic fiber and the hydrophobic matrix. Hybrid composites were developed by the compression molding technique and formulated based on the weight fraction of fibers. Tensile, flexural, and impact strength and hardness samples were prepared as per ASTM D 3039, ASTM D 790, ASTM D 256, and ASTM D 2240, respectively. The effects of alkaline treatment on developed hybrid composites were investigated. The developed hybrid composites with 20% wt. snake grass and 10% wt. areca fiber present interesting mechanical properties with a tensile strength of 58 MPa, flexural strength of 124 MPa, impact strength of 5.24 kJ/m2, and hardness of 88. The results indicate that maximum mechanical properties were obtained for alkaline-treated fiber composites with 20% wt. snake grass fiber compared to untreated fiber composites owing to better adhesion between the treated fiber and the matrix. The effect of alkaline treatment was analyzed by Fourier transform infrared. The fractured surfaces of tested samples were analyzed by scanning electron microscopy.

AbstractIn this paper, an attempt has been made to investigate the effect of coir fiber addition along with the banana fiber in low-density polyethylene (LDPE) to develop cost-effective and high-performance composite material. The composite samples were prepared at fixed fiber content (25 wt%) and with varying relative weight fraction of banana and coir fiber using compression molding technique. The effect of hybridization was analyzed through the mechanical properties (tensile, flexural, and impact), thermal stability, morphological behavior, and water absorption behavior. Additionally, scanning electron microscopy studies had been carried out on the tensile fractured surface for all composite samples to examine the fracture behavior of the composite samples. The results showed that the incorporation of coir fiber into the banana fiber composites of up to 50% by weight led to enhancement of the mechanical properties and thermal stability and to reduction of the water absorption capacity of the banana fiber/LDPE composites.

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.

As we all know that India is known for its agricultural products rather than its industrial goods. Farmers produce crops and they pet several animals. The waste produced from their animals and crops are utilized by them to some extent but due to unawareness a lot of material goes on waste. Some of these wastes are Bagasse fiber and chicken feather. Also these alternate materials are environment Friendly as well as biodegradable. In poultry industry chicken feather is waste material but it posses high toughness and insulation and is also used as good reinforcing material in polymer matrix composite due to low density, low cost and high aspect. Bagasse having high tensile strength contains about 40% cellulose, 30% hemicelluloses, and 15% lignin which are modified by creating quionones in lignin portion of the fiber and reacting with the furfural alcohol to increase their adhesiveness. Short Natural fibers like chicken and long fibers like bagasse were used in hybrid combination and the fiber weight fraction of 5%, 55% and 40% were used for the fabrication of the composite in epoxy Resin. This composite is manufactured using hand layup process. Mechanical properties of composite are determined through hardness and impact tests. Water absorption tests were conducted by immersing specimen in a water bath at room temperature for different time durations.

Due to environmental and energy conservation concerns, a thrust towards low-cost lightweight materials has resulted in renewed interest in the development of sustainable materials that can replace nonbiodegradable and environmentally unfriendly materials in reinforced composites. In this study, mechanical properties of a hybrid composite consisting of polyester resin reinforced with a blend of sisal and cattail fibres were evaluated. The composite was fabricated using a hand lay-up technique at varying hybrid fibre weight fractions (5 to 25 wt%) while maintaining a constant fibre blend ratio of 50/50. Composites were also prepared at a constant fibre weight fraction of 20% while varying the fibre blend ratio between 0 and 100%. Fabricated composites were then characterised in terms of flexural, tensile, compressive, and impact strengths following ASTM and ISO standards. Results showed that, at a constant fibre blend ratio of 50/50, there was increase in the mechanical properties as the fibre weight fraction increased from 5 to 20%. At a constant fibre weight fraction (20%), a positive improvement in flexural, tensile, and compressive properties was registered as the fibre blend ratio varied between 0 and 75% with optimal values at a sisal/cattail ratio of 75/25. The current study suggests that blending sisal and cattail fibres for production of polyester composites yields hybrid composites with enhanced mechanical properties.

The aim of this study is to investigate the influence of fibre weight fraction on flexural and dynamic mechanical properties of Arenga pinnata fibre and its hybrid epoxy composites. In this work, four (4) composites configurations were fabricated using hand lay-out by varying fibre weight ratios between Arenga pinnata (AP) and glass fibre (GF); AP100% - 0%GF, AP70% - 30%GF, AP30% - 70%GF and AP0% - 100%GF, respectively. The flexural modulus indicates that the pure Arenga pinatta composites (AP100%-0%GF) are stronger than both hybrid and pure glass fibre composites (AP0%-100%GF). Increasing fibre weight fraction of glass fibre has resulted lower flexural properties. By dynamic mechanical analysis (DMA), storage modulus of pure Arenga pinnata composites is always higher and have better thermal resistance as compared to the pure glass fibre composites. The result indicates that that Arenga pinatta fibre reinforced with epoxy composites have a great opportunity similar to that glass fibres composites counterpart in engineering application.

The polymer composite material’s thermomechanical properties with fiber as reinforcement material have been widely studied in the last few decades. However, these fiber-based polymer composites exhibit problems such as fiber orientation, delamination, fiber defect along the length and bonding are the matter of serious concern in order to improve the thermomechanical properties and obtain isotropic material behavior. In the present investigation filler-based composite material is developed using natural hemp and high thermal conductive silver nanoparticles (SNP) and combination of dual fillers in neat epoxy polymer to investigate the synergetic influence. Among various organic natural fillers hemp filler depicts good crystallinity characteristics, so selected as a biocompatible filler along with SNP conductive filler. For enhancing their thermal conductivity and mechanical properties, hybridization of hemp filler along with silver nanoparticles are conducted. The composites samples are prepared with three different combinations such as sole SNP, sole hemp and hybrid (SNP and hemp) are prepared to understand their solo and hybrid combination. From results it is examined that, chemical treated hemp filler has to maximized its relative properties and showed, 40% weight % of silver nanoparticles composites have highest thermal conductivity 1.00 W/mK followed with hemp filler 0.55 W/mK and hybrid 0.76 W/mK composites at 7.5% of weight fraction and 47.5% of weight fraction respectively. The highest tensile strength is obtained for SNP composite 32.03 MPa and highest young’s modulus is obtained for hybrid composites. Dynamic mechanical analysis is conducted to find their respective storage modulus and glass transition temperature and that, the recorded maximum for SNP composites with 3.23 GPa and 90°C respectively. Scanning electron microscopy examinations clearly illustrated that formation of thermal conductivity chain is significant with nano and micro fillers incorporation.
