A brief review on mechanical and thermal properties of banana fiber based hybrid composites

AbstractThe usage of banana natural fibers along with polymer matrix composites had created much interest among the researchers due to their low cost, easy availability, strength and enhancement in properties such as mechanical, wear, electrical and thermal. Banana plant is cultivated all over the world which is familiarly used as food products especially banana fruit as well as many household items made from banana fibers. The natural fiber extracted from the banana stem proves to be a potential reinforcement in the composite manufacturing. This review is very much needed because of the enormous research reported on the banana fiber reinforced polymer composites, with such an excellent property offered by this banana fiber reinforcement the impact of hybridization and its need also to be addressed. This brief review article gives a detail information about the combinations of various hybrid composites produced using the banana fiber along with various other natural/synthetic fibers in the polymer matrixes and its performance improvement especially in the mechanical and thermal properties. From the review it was inferred that 30–50% increase in all the mechanical properties such as Tensile, Flexural and Impact strength. Also in addition an enhancement in thermal and moisture resistance also noted. In addition during this review the research gap observed is that the development of bio composites based on banana fiber is very limited and also the influence of banana fiber along with bio resin needs to be studied. The properties such as fatigue, fire resistance also to be analyzed using the banana fiber reinforcement.

The main objective of this work was to investigate the effect of hybridization on the mechanical and thermal properties of intralaminar natural fiber-reinforced hybrid composites based on sisal. Ramie, sisal and curauá fibers were selected as natural fiber reinforcements for the epoxy matrix based composites, which were produced by the hand lay-up technique. Tensile, flexural and impact tests were carried out according to American society for testing and materials (ASTM) standards to characterize the hybrid composites, while differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) were used to evaluate the thermal properties. It was found that the mechanical properties are improved by hybridization of sisal based composites. The thermal analysis showed that the hybridization did not significantly affect the thermal stability of the composites. A scanning electron microscopy (SEM) was used to examine the fracture surface of the tested specimens. The SEM images showed a brittle fracture of the matrix and fiber breakage near the matrix.

Moisture absorption of natural fiber-based composites is one of the major problems in outdoor applications. The present study deals with the effect of moisture absorption on mechanical and thermal properties of unmodified/modified Date Palm Leaf (DPL) with glass fiber-based hybrid composites. Natural fibers were modified with alkaline treatment to improve fiber and matrix bonding. Conventional hand lay-up technique is used to fabricate the composites with varying different wt.% of treated and untreated short DPL with constant wt.% of glass fiber and prepared with random oriented manner. The combine effect of hydrophilic and hydrophobic nature find out as the study based upon the natural with synthetic fiber hybrid composites. Mechanical behaviour of the epoxy-based hybrid composites were characterized by using tensile, flexural and hardness test. The results revealed that significant improvement in mechanical properties by the addition of different weight percentage of modified DPL. Different thermal properties of the composites were described by using Thermo Gravimetric Analyzer (TGA) and Differential Scanning Calorimetric (DSC). Morphological investigation was carried out to by using scanning electron microscope. All the properties of untreated natural fiber reinforced composites were mostly affected by the influence of water absorption as compared with chemically treated based 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.

The Impact

The hybrid composites were fabricated by taking cheaply available empty fruit bunch fibers and jute fibers trilayers as reinforcement in epoxy matrix using simple hand lay-up-technique. Thermal, mechanical and morphological properties were characterized. The notched izod impact strength of most hybrids increased with respect to the virgin matrix. The laminates coupled with 2-Hydoxy ethyl acrylate (HEA) showed better impact properties than the one without coupling agent. The addition of fibers and coupling agent considerably improved the thermal stability (i.e., decomposition and residue content) of the hybrids. The thermal properties measured by thermogravimetric analysis (TGA) showed that fibres and coupling agents improved thermal properties. The impact fractured composite specimens were analyzed using field emission scanning electron microscopy (FESEM) to know the morphological behaviour.

Abstract: The world that is evolving at a very fast pace, the anxiety of the environment pollutions increasing has tip the necessity for new eco-friendly materials, researchers have started to develop sustainable materials that are renewable as well as biodegradable in nature. The natural fibers have certain advantages above synthetic fiber materials, they are lower in cost and density with comparable strength. In the present study, banana fiber is reinforced in the epoxy matrix and a composite material is prepared and impact strength of these composites are estimated. This composite samples are prepared by Wet lay-up method with varying banana fibers volume percentages by (10%, 20%, 30%, 40%) and by changing the fibers orientation in the epoxy matrix by (00 ,900 , woven Bi-directional). The results shows that there is gradual increase in the impact strength of the epoxy for 900 banana fiber orientation, the optimum results were found for 40% banana fiber and 60% epoxy resin, as for woven BD there was an increase in the impact strength up to 20% banana fiber reinforcement, as for 00 orientation the strength increases up to 10% fiber reinforcement above this there was a drastic reduction in the impact strength.

Ecological Concern

Currently, the growing field of technology has paved the way for using environmental friendly resources; in particular, plant origin holds ecological concern and renewable aspects. Currently, natural fiber composites have widening attention, thanks to their eco-friendly properties. In the present work, the composite material is reinforced with natural fibers from the bark of banana trees (banana fibers), a material available in Vietnam. Banana fibers are extracted from banana peels, pretreated with NaOH 5%, and then cut to an average length of 30 mm. Banana fiber is reinforced for epoxy resin Epikote 240 with mass percents: 10 wt.%, 15 wt.%, 20 wt.%, and 25 wt.%. The results were evaluated through structural morphology (SEM), mechanical properties, fire resistance, and thermal properties. Experimental results show that the tensile, compressive, and impact strengths of biosynthetic materials up to 20% by weight have increased compared to epoxy neat. Flame retardant and thermal properties are kept stable; 20 wt.% banana fiber gives a limiting oxygen index of 20.8% and satisfactory thermal stability.
