Alkali treatment coupled with high pressure defibrillation and acid have been tried on banana fibers obtained from the pseudo stem of plant Musa sapientum. The structure morphology found to be affected basis concentration alkali also applied. Steam explosion in alkaline medium followed by acidic is effective depolymerization fiber produce nanowhiskers. chemical constituents raw steam exploded were analyzed according ASTM standards. Structural analysis was carried out FTIR XRD. diameter...
Biodegradable nanocomposite films were prepared by incorporation of cellulose nanofibrils (CNF) into alginate biopolymer using the solution casting method. The effects CNF content (2.5, 5, 7.5, 10 and 15 wt %) on mechanical, biodegradability swelling behavior determined. results showed that tensile modulus value increased from 308 to 1403 MPa with increasing 0% 10%; however, it decreased further increase filler content. Incorporation also significantly reduced percentage water solubility...
This paper describes the tensile, impact, flexural properties and aging behavior of short banana fiber reinforced polyester composites with special reference to effect length content. Maximum tensile strength was observed at 30 mm while impact gave maximum value for 40 length. Incorporation 40% untreated fibers a 20% increase in 341% strength. On treatment silane coupling agent, showed 28% 13% Aging studies decrease composites. The experimental values were compared theoretical predictions...
Abstract Considerable interest in food packaging research has been prompted by the rising environmental impact of waste, customer awareness for readily accessible foods with extended shelf life, and ecological consciousness about scarcity natural resources. The utilization plastic-based resulted a significant concern due to accumulation substantial quantities plastic surrounding areas. Research efforts are being motivated health considerations pursuit developing biodegradable films. Besides,...
Abstract The water sorption characteristics of banana fiber–reinforced polyester composites were studied by immersion in distilled at 28, 50, 70, and 90°C. effect hybridization with glass fiber the chemical modification on absorption properties prepared also evaluated. In case hybrid composites, uptake decreased increase content. chemically modified was found to be dependent treatment done surface. Weight change profiles higher temperature indicated that diffusion is close Fickian. showed a...
Abstract Cellulosic fibers have been used as cost-cutting fillers in plastic industry. Among the various factors, final performance of composite materials depends to a large extent on adhesion between polymer matrix and reinforcement therefore quality interface. To achieve optimum end product, sufficient interaction resin cellulosic material is desired. This often achieved by surface modification or filler. Banana fiber, obtained from pseudo-stem banana plant (Musa sepientum) bast fiber with...
The static and dynamic mechanical properties of banana glass woven fabric-reinforced polyester composites have been determined with special reference to the effect fiber volume fraction, layering pattern, weaving architecture. Even though articles related natural are abundant in literature, work on textile is found be rare. Composites high tensile strength can obtained using fabric form, two layers fabric. impact increases number fraction. By incorporating fabric, G0 curve shows an improved...
Hybrid composites of glass and banana fiber (obtained from the pseudo stem Musa sapientum) in polyester matrix, are subjected to dynamic mechanical analysis over a range temperature three different frequencies. The effect on storage modulus (E ′ ), loss ′′ factor or damping efficiency (tan δ) is determined. All properties compared with those neat samples un-hybridized composites. effects layering pattern two fibers ultimate viscoelastic behavior also investigated. Composites prepared as...
Abstract This article deals with the aspects of interfacial and surface characterization natural fibers their composites. Vegetable composites have attracted attention scientists worldwide because favorable properties. The different chemical modifications been discussed. adhesion between fiber matrix is a major factor in determining response interface its integrity under stress. Therefore utmost importance. Both polymer can be modified to obtain strong interface. Various treatments being...
Banana fiber obtained from the sheath of banana plant, Musa sapientum, has been used in preparation composites with polyester matrix. The effect loading on dielectric constant, volume resistivity, and loss factor were determined special reference to frequency. fibers modified chemically order have better compatibility surfaces characterized using techniques like solvatochromism, zeta potential measurements, X-ray Photo electron spectroscopy (XPS), Scanning Electron Microscopy (SEM). surface...
Composites of woven sisal in polyester matrix using three different weave architectures: (plain, twill, and matt) were prepared a resin transfer molding technique with special reference to the effect viscosity, applied pressure, architecture, fiber surface modification. More than modification, architecture was found have maximum influence on ultimate composite properties. The permeability, which is related wetting, be dependent morphology. Sisal fibers form, volume 32%, improve properties...
