Assessment of compressive and wear performance of waste marble powder and short banana fiber reinforced epoxy composites

In the research work, conventional hand layup technique will be adopted to fabricate waste marble powder (WMP) filled banana fiber (BF) with epoxy resin composite for analysis of mechanical characteristics like compressive stress, compressive strain, and wear rate. The waste marble powder weight percentage will be varied from 0 wt% to 20 wt% at 5 wt% interval. The chopped banana fiber weight percentage will be varied from 15 wt% to 35 wt% at 5 wt% interval. The epoxy resin weight percentage will be kept as 65 wt% for all samples. The specimens for compression and wear test will be prepared as per ASTM standards. The maximum compressive stress, compressive strain, and wear rate of the all composites will be evaluated through Universal Testing Machine and Pin on Disc Machine correspondingly. The outcomes from the above tests will be compared to choose the optimum filler/fiber ratio. The prepared composites will be aimed to use in packing applications.

Influence of glass fiber hybridization on flexural and water absorption behaviour of banana fiber reinforced epoxy composites

The majority of vehicle constructions used in the aviation, automotive, and marine industries are subject to various loads. These constructions are more vulnerable to flexural stress, as can be observed. Under the influence of flexural loads, structures can gradually suffer harmful deterioration. The resistance of curved banana/glass fiber reinforced hybrid composites to flexural stress is very important. This research is aimed to examine the influence of glass fiber hybridization on flexural and water uptake percentage of banana fiber reinforced epoxy composites. Glass fiber is a manmade fiber composed mainly of silica, known for its high strength, rigidity, and resistance to heat and chemicals. Banana fiber, in contrast, is a natural fiber derived from the banana plant, offering moderate strength, flexibility, and biodegradability. Glass fiber finds applications in industries requiring strong and durable materials, while banana fiber is sought after for its sustainable and eco-friendly characteristics. In this work, we have fabricated the banana fiber reinforced epoxy composites by adding glass fiber from 0 to 20 weight% through hand layup technique. Then, flexural test and water absorption test has been investigated as per ASTM standards and compared the hybridization effect of glass fiber. From the findings, it is determined that, increase in weight % of glass fiber increasing the flexural behaviour and water resistance of the composites.

In this research, the composite materials were created by a traditional hand layup method with waste marble powder packed banana fibre, epoxy resin, and the study will evaluate several mechanical parameters, such as flexural stress, flexural strain, flexural modulus, and hardness. The waste marble powder weight percentage will be varied from 0 wt% to 20 wt% at 5 wt% interval. The chopped banana fiber weight percentage will be varied from 15 wt% to 35 wt% at 5 wt% interval. The epoxy resin weight percentage will be kept as 65 wt% for all samples. The specimens for flexural and hardness test will be prepared as per ASTM standards. The Universal Testing Machine (UTM) and the Vickers Hardness Testing Machine will be used to determine the maximum flexural strength and flexural modulus at 72.4 MPa and 2.76 GPa, respectively. The results from the above tests will be compared to choose the optimum filler/fiber ratio. The prepared composites will be aimed to use in packing applications.

Impact of SiC on The Mechanical and Thermal Properties of Banana Fiber Reinforced Epoxy Composites

Abstract: This work investigates the mechanical properties (Tensile Strength & Impact Strength) and thermal properties (Thermal conductivity & diffusivity) of a natural fiber composite that includes banana fiber as reinforcement in epoxy (LY 556) matrix as the base material with the addition of silicon carbide particles by 5% and 10% by weight. This Banana Fiber Reinforced Epoxy Composite (BFREC) prepared by hand lay-up technique. After curing for a sufficient period, samples taken out and tested. The results suggest that on increasing SiC wt% in the matrix, there is enhancement of its tensile strength, impact strength, and thermal conductivity. Bulk density also increases while thermal diffusivity decreases. Due to low density as compared to metals, improved tensile and impact strength and low elongation at break of banana fibers, BFREC composite with SiC have very good potential use in the various sectors.

Processing of high weight fraction banana fiber reinforced epoxy composites using pressure induced dip casting method

The objective of this work is to realize new polymer composite material containing high amount of natural fibers as a bio-based reinforcement phase. Short banana fiber is chosen as a reinforcement material and epoxy polymer as a matrix material. About 77 wt.% of banana fibers were reinforced in the epoxy polymer matrix composite, using pressure induced fiber dipping method. Nanoclay particles were infused into the banana fibers to improve the fiber matrix interface properties. The nanoclay infused banana fiber were used to reinforce epoxy composite and its properties were compared with untreated banana fiber reinforced epoxy composite and banana fiber reinforced epoxy filled with nanoclay matrix composite. The surface characteristics of these composites were examined by electron microscope and the result shows well dispersed fibers in epoxy matrix. Thermal (thermogravimetry analysis and dynamic mechanical analysis), mechanical (tensile and fiber pullout) and water barrier properties of these composites were examined and the result showed that the nanoclay infused banana fiber reinforced epoxy composite shows better and improved properties. Improved surface finish composite was also obtained by this processing technique.

Compressive characteristics of unmodified and nanoclay treated banana fiber reinforced epoxy composite cylinders

The objective of this work was to prepare a natural fiber reinforced composite product by using nanoparticle technique method. Nanoclay particles were infused into the banana fiber and these modified banana fibers were then reinforced in epoxy polymer composites. A short banana fiber reinforced epoxy polymer composite cylinder was prepared by resin impregnation method, and the compressive, tensile, interfacial and energy absorption characteristics were studied. The properties of nanoclay infused banana fiber reinforced composites were compared with alkaline (NaOH) treated and untreated banana fiber reinforced epoxy composites. It was observed that the nanoclay infused banana fiber composites has resulted in 17%, ∼2 times and 43% improved compressive yield stress, modulus and strength when compared with untreated banana fiber reinforced epoxy composite cylinder. However, nanoclay infusion induces brittleness into the fiber affecting the elongational properties. Tensile, flexural and short beam properties show that the reinforcement effect of nanoclay was higher in flexural and short-beam modes when compared with tensile mode, due to higher level of surface interaction of nanoclay particles in flexural and short-beam modes. About 2 times improved energy absorption properties were obtained in nanoclay infused banana fiber reinforced epoxy composites when compared with untreated banana fiber reinforced epoxy composites. Microscopy examination revealed that the nanoclay infusion in fiber improved fiber-matrix interfacial and load transfer characteristics leading to the higher level of property improvement in nanoclay infused banana fiber reinforced epoxy composites. The outcome of the result suggest that the nano-technique is very much useful and can be simply applied onto the natural fibers to realize the potential application of these materials.

Tribological Properties of Nanoclay-Infused Banana Fiber Reinforced Epoxy Composites

The objective of this work is to study the tribological properties of natural fiber based composites using nanotechnology. The naturally available banana plant fibers were treated with nanoclay particles, and these treated fibers were then reinforced in an epoxy polymer to form composites. The friction and wear properties of nanoclay-treated banana fiber (NC-BF) reinforced composites were compared with untreated banana fiber (UT-BF) reinforced composites. Short NC-BF- and UT-BF-reinforced composites with fiber concentration ranging from 20 wt % to 60 wt % were prepared by the vacuum resin infusion processing method. The result indicates that the NC-BF-reinforced composites have shown improved friction and wear properties. Microscopy examination revealed that NC-BF-reinforced composites were able to form a transfer layer between the wear test specimen wear surface and counter face, resulting in improved wear properties. The nanoclay particles also induce increased hardness and friction to the composites and improve braking properties.

However, ANN gives better result than the regression.

Investigations on Thermal Conductivities of Jute and Banana Fiber Reinforced Epoxy Composites

The Jute and Banana fibers are used as reinforcement in epoxy resin matrix for making partially green biodegradable material composite via hand lay-up technique. The thermal conductivity of the jute fiber epoxy composites and banana fiber epoxy composites at different volume fraction of the fiber is determined experimentally by using guarded heat flow meter method. The experimental results had shown that thermal conductivity of the composites decrease with an increase in the fiber content. Experimental results are compared with theoretical models (Series model, Hashin model and Maxwell model) to describe the variation of the thermal conductivity versus the volume fraction of the fiber. Good agreement between theoretical and experimental results is observed. Thermal conductivity of Banana fiber composite is less when compared to that of Jute composite which indicates banana is a good insulator and also the developed composites can be used as insulating materials in building, automotive industry and in steam pipes to save energy by reducing rate of heat transfer.
