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.

Natural fibers are increasingly used in composites because of their low cost and good mechanical properties. Cement reinforced with natural fibersis contemplates as a new generation of construction materials with superior mechanical and thermal performance. This study of three sizes’effect of Doum palm fiber explores the mortar’s behavior reinforced with different fiber ratio. The aim is to determine the optimal addition to improve mechanical and thermal properties of natural fiber reinforced cements. Physical, mechanical and thermal properties of composite are examined. Tensile properties of Doum fibers are verified to determine their potential as reinforced material. Findings prove that the use of alkali-treated Doum fiber as reinforcement in cement mortar composite leads to the upgrading of the mechanical properties including thermo-physical properties against composites reinforced with raw fibers and control cement mortars. While, the compression and flexural strength of the cement mortar reinforced with alkali-treated Doum fiber with diameter 0.3 mm (CT3) are metered to be 11.11 MPa, 5.22 MPa, respectively for fiber content 0.5%. Additionally, based on thermo-physical tests, it is assessed that the thermal conductivity and diffusivity decrease for cement mortar reinforced with Doum fiber with diameter 0.2 mm (CT2).

The present environmental condition indicates the immediate need for sustainable materials containing mainly natural elements for composite fabrication. Encouragement of natural fibers in composite materials can significantly reduce the greenhouse effect and the high cost of manufacturing synthetic fiber-based polymer composites. Hence, this study aimed to investigate the physio-mechanical properties of banana fiber (BF) fiber -based epoxy (EP) composites filled with walnut shell powder (WNP). Fabrication was carried out by mixing and cold pressing with fixed BF proportion and varying percentages of WNP (0%, 5%, 10%, 15 wt. %). The results obtained in the study suggest the mechanical properties of the BF/EP composite were enhanced with the addition of WNP as a filler. This is because the WNP filler occupies the spaces in the composite, which bridge the gaps between the banana fibers and the epoxy matrix; also, the inclusion of walnut powder in the BF/EP composites greatly enhanced their wear resistance. The microstructural properties of the composites were examined by scanning electron microscopy (SEM).

Abstract Natural fiber-reinforced polymer composites have been widely explored by many researchers due to their improved modulus and lightness compared to other conventional construction materials such as wood, metal, and steel. Cultivators only harvest banana and plantain fruits for food and leaves for food wrapping. The other portions of the plant are considered as wastes and a potential resource of natural fibers used as reinforcement in composites. Over the years, a plethora of research works has been done on banana and plantain fibers as fillers in plastic composites. Comprehensive catalogues of preparation techniques and mechanical properties were presented. The mechanical properties of banana fiber reinforcement in polyester and epoxy composites were compared to and contrasted with those of other natural fibers to elucidate its superiority or inferiority to those materials. This work gives an overview of the current state of knowledge of banana fiber-reinforced composites alongside the available research gaps.

This paper compares the mechanical properties of different natural fiber composites produced by rotational molding as a way of waste valorization from campaigns to control invasive plant species in Macaronesia. Rotomolded parts produced with polymeric matrices (polyethylene) and filled with up to 20% by weight of cellulosic fibers obtained from Arundo donax L., Pennisetum setaceum, and Ricinus communis plants were characterized in terms of tensile, flexural, and impact strength. It was found that the sieving of natural fibers allowed for their introduction in higher loadings, from 10 (for un-sieved material) to 20%; fiber size greatly affected the mechanical properties of the final parts, although some combinations were proven not to reduce the mechanical properties of the neat resin. This study is a first approach to the valorization of residues obtained from periodic campaigns of the control of invasive species performed by public authorities, usually at the local level. It is important to highlight that the main objective of this research did not focus on economically profitable activity; instead, it was focused on the reduction of wastes to be disposed from ecosystem maintenance actions and the investment of potential income into preservation policies.

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.

Banana/Coir fiber reinforced polypropylene hybrid composites was formulated by using twin screw extruder and injection molding machine. Specimens were prepared untreated and treated B/C Hybrid composites with 4% and 8% of MA-g-PP to increase its compatibility with the polypropylene matrix. Both the without MA-g-PP and with MA-g-PP B/C hybrid composites was utilized and three levels of B/C fiber loadings 15/5, 10/10 and 5/15 % were used during manufacturing of B/C reinforced polypropylene hybrid composites. In this work mechanical performance (tensile, flexural and impact strengths) of untreated and treated (coupling agent) with 4% and 8% of MA-g-PP B/C fibers reinforced polypropylene hybrid composite have been investigated. Treated with MA-g-PP B/C fibers reinforced specimens explored better mechanical properties compared to untreated B/C fibers reinforced polypropylene hybrid composites. Mechanical tests represents that tensile, flexural and impact strength increases with increase in concentration of coupling agent compared to without coupling agent MA-g-PP hybrid composites . B/C fibers reinforced polymer composites exhibited higher tensile, flexural and impact strength at 5% of Banana fiber, 15% of fiber Coir in the presence of 8% of MA-g-PP compared to 4% of MA-g-PP and untreated hybrid composites. The percentage of water absorption in the B/C fibers reinforced polypropylene hybrid composites resisted due to the presence of coupling agent MA-g-PP and thermogravimetry analysis (TGA) also has done.
