Extraction, Treatment and Characterization of Banana Pseudo-Stem Fibers as Potential Utility in Textile Industry

Extraction, treatment and characterization of banana pseudo stem fibres was achieved. The study revealed that water retting is the best way to extract fibers, however the gummy materials bending fibres together must be weakened by boiling the fibres rich material prior to retting where the fibres were able to be extracted at 14th day of retting. The fibers were treated using NaOH for scouring while bleaching was carried out using H2O2. The treatment of fibers was conducted to get rid of fat, wax and other impurities as well as undesired colors bonded to fibers that could not be removed through water retting. The best scouring concentration of NaOH was found to be 17.5 % while the best bleaching concentration of H2O2 was found to be 2 %. More so, FTIR was carried out for both treated and untreated fibers and it was shown that wax, fat and other impurities can be removed by fibres’ scouring and bleaching. This was further confirmed by the use of Soxhlet to extract ethanol-benzene extract from both treated and untreated fibres, where untreated fibres showed a considerable weight loss while the treated fibers did not show any weight loss. Thereafter, mercerization was carried out and it was found out that the best mercerization concentration of NaOH is 15%. Furthermore, the quantitative analysis of the banana pseudo-stem fibers revealed that the fibers have, ethanol-benzene extractives of 4.2 %, pectin content of 3.07%, Lignin content of 18%, cellulose content of 68.3% and ash content of 4.2 %. The fibers showed a water, oil and vapor absorption of 71%,59 % and 8% respectively. Also, the thermal analysis showed that the degradation temperature is 370 0C while the fibers started to display thermal instability at 290 0C. Moreover, SEM and XRD analysis showed that the treatment of fibres participated in removal of wax and oil as well as other gummy materials, which also is in line with FTIR results obtained.

EXPERIMENTAL STUDY OF THE CHLORIDE-ION PERMEABILITY OF BAMBOO-FIBER-REINFORCED CONCRETE

This study investigated the chloride-ion permeability of C30 concrete by adding bamboo fibers with different treatments (untreated, treated with calcium hydroxide solution and treated with sodium hydroxide solution) and different dosages. Three testing methods, namely the electric-flux method, AC test method and the RCM method, were used to characterize the concrete. Parameters such as electric-flux value, AC resistivity and chloride-ion diffusion coefficient were obtained. Results showed that the surface impurities of the bamboo fibers treated with calcium hydroxide solution were removed and the thermal stability of the bamboo fibers was improved, which can effectively enhance the chloride-ion permeability of concrete. Compared to untreated bamboo fibers, the improvement rate was between 14 % and 17 %. Sodium hydroxide is a strong alkaline solution, which can easily disrupt the structure of bamboo fibers and reduce the resistance of concrete to chloride-ion penetration. The best chloride-ion permeability was achieved when the bamboo fiber content reached 2 %. The electric-flux method, AC test method, and the RCM method were mutually validated with good correlation. It is recommended to choose a suitable and simple method for testing. Bamboo-fiber concrete lays a solid foundation for the future transformation of the civil-engineering industry.

Development and Characterization of a PLA Biocomposite reinforced with Date Palm Fibers

Despite the promising potential of bio-composites derived from plant fibers due to their ecological and economic benefits, challenges persist in their preparation, restricting their commercial applications. These challenges are primarily associated with developing suitable methods, acquiring appropriate equipment for treating plant fibers, and addressing the time constraints in preparation. This study aims to contribute to the development and characterization of a new biocomposite and biodegradable material based on natural fibers produced through hot compression. The newly developed biocomposite comprises commercial biodegradable poly-lactic acid (PLA) as a matrix and untreated fiber fabric extracted from date palms as reinforcement. The use of untreated fiber fabric has successfully overcome the preparation difficulties. Experimental results on the new biocomposite reveal the strong adhesion between its fibers and the matrix, emphasizing the significant impact of choosing the right manufacturing conditions on the developed mechanical properties.

Experimental and numerical investigation of the usability of nonwoven hemp as a reinforcement material

This study presents experimental and numerical investigations on the use of chemically untreated and recyclable hemp fibers as reinforcement for outer wrapping in reinforced concrete beams. Hemp fibers, recognized as an alternative to Carbon Fiber Reinforced Polymer (CFRP) and Glass Fiber Reinforced Polymer (GFRP), were utilized in three forms: unwashed hemp, washed hemp, and hemp rope. The materials underwent distinct tensile tests, compression tests on cylinder specimens (15×30 cm), and 4-point bending tests on reinforced concrete beams (15×25×200 cm) wrapped with CFRP, GFRP, Glass Fiber Chopped Strand, Geotextile, and NFRP (Unwashed hemp, washed hemp, and hemp rope). Additionally, the epoxy used in wrapping underwent adhesive and tensile tests. Despite swelling during adhesion, untreated hemp demonstrated effectiveness in load-carrying capacity, positioning it as a viable alternative to costly petroleum-derived materials. A finite element model compared the experimental results, confirming the efficacy of untreated hemp fibers in reinforced concrete applications. This study contributes not only to the exploration of sustainable construction materials but also underscores the potential of untreated hemp fibers in meeting the demand for eco-conscious alternatives in structural reinforcement.

Investigation on the potential of Eulaliopsis binata (babiyo) as a sustainable fiber reinforcement for mortar and concrete

The production of synthetic materials emits harmful gases, driving researchers to seek eco-friendly alternatives, leading to increased demand for natural fiber-based composites in various industries. With advantages like cost-effectiveness, renewability, and biodegradability, natural fiber reinforced composites gain popularity in concrete applications. Their use in concrete has gained global acceptance for its smaller carbon footprint, reduced energy consumption, and minimized wastage. This research aims to evaluate the suitability of Eulaliopsis binata (EB) fiber in mortar and concrete applications. Mortar samples were prepared using different proportions of alkaline-treated EB fibers (0%, 0.25%, 0.5%, 0.75%, 1% and 1.25% by total weight of mortar) in a cement-sand-water mixture with a 1:1:0.35 ratio. Additionally, concrete with a mix proportion of 1:2.15:3.13 (cement: fine aggregate: coarse aggregate) and a water-cement ratio of 0.618 was prepared. The flexural strength test was conducted using plain concrete as well as concrete with untreated and epoxy-treated EB fiber bars of varying diameters. The results revealed that EB fiber-reinforced mortar exhibited a notable increase in flexural and splitting tensile strength, with a 10.85% and 6.23% improvement compared to plain mortar at 0.75% EB fiber content, while compressive strength decreased. Similarly, concrete reinforced with untreated and epoxy-coated EB fiber bars of 14 mm diameter demonstrated 12.32% and 13.27% higher flexural strength, respectively, than that of unreinforced concrete. These results highlight the potential for affordable green concrete production, supporting sustainable infrastructure development. The EB fiber usage presents an encouraging pathway for environmentally conscious construction practices with reduced environmental impact.

The Physicomechanical and Interfacial Properties of the Vetiveria Zizanioides Fiber Reinforced Polymer Composites

The effects of chemical treatment and vetiveria zizanioides (vetiver) loading on the physicomechanical, morphological, and weather tests of the vetiver fiber (VF)-filled polypropylene (PP) composites were investigated. Raw VF was chemically treated with sodium dodecyl sulfate (SDS) and SDS-pretreated benzoyl chloride to increase its compatibility with the PP matrix. The mechanical properties of the PP/VF composites, including tensile strength, tensile modulus, impact strength, hardness, and water absorption, were increased by raising the fiber content to the optimum level of 30 wt%. The resultant composites' mechanical characteristics and water desorption were improved by adding SDS and SDS-pretreated benzoyl chloride for the VF. PP/VF composites containing benzoyl chloride after SDS pretreatment show better mechanical performance when compared to untreated and SDS-treated fiber composites. SEM studies showed that the treatment of the fibers enhanced the interfacial interaction between PP and VF, verifying the mechanical properties of the composites. Water absorption tests revealed that SDS-pretreated benzoyl chloride composites absorbed less water than untreated counterparts and even SDS-treated composites. Sodium dodecyl sulfate-pretreated benzoyl chloride composites exhibited less loss in tensile strength and tensile modulus during weather testing than sodium dodecyl sulfate-treated and untreated composites.

EFFECTS OF CHEMICAL TREATMENT ON CONSTITUENTS, TENSILE STRRENGTHS AND MICROSTRUCTURAL CHARACTERISTICS OF NATURAL FIBERS

Recently, natural fibers have distinguished themselves as an exceptional material that provides a cheap and plentiful substitute for synthetic fibers which are expensive and non-renewable. In this study, selected natural fibers from banana, plantain, and sisal were examined in order to ascertain the possibility or otherwise of plantain fiber which is common in Nigeria but are yet to be recognized globally. Selected fibers were extracted and treated to modify their constituents and surface morphology using sodium hydroxide solution. Both treated and untreated fibers were characterized and, from the results, improvements in fiber properties were noticed. The impact of this chemical modification on constituents, tensile strengths and surface morphology of fiber were examined using an Instron testing machine and scanning electron microscope (SEM). The results showed that chemical treatment increased the fiber’s tensile strength with plantain having optimum value of 689 MPa after treatment while the removal of some fiber constituents caused the surface morphology to be rough. Its cellulose contents before and after treatment was 45.64 and 51.11 %, respectively. Thus, it was found that alkaline treatment improved the quality of the fiber making the fiber an acceptable replacement for synthetic fibers in composite creation.

Dyeability and mechanical properties of banana fiber reinforced polypropylene composite

AbstractBanana fibers being highly strong and biodegradable, have always been an interesting aspect of polymer science. The research examines the pretreatment process to enhance the dyeability of banana fibers with synthetic dyes, followed by the preparation of polypropylene (PP) composites with dyed fibers to explore their mechanical properties. Raw banana fibers were extracted from the pseudo stems of banana plants for pretreating with sodium hydroxide and hydrogen peroxide and further dyed in the exhaust method using direct, basic, reactive, and vat dyes. Despite a decrease in fiber strength, the scoured‐bleached fibers appeared whiter and lustrous compared to untreated fibers. Direct dye exhibited a higher color strength (K/S) value of 20.7 and better wash fastness on average of 4‐3 rating compared to basic dye. Later polypropylene sheets were prepared using a Hot Plate Molding Machine, and composite specimens were fabricated by sandwiching the fibers between PP sheets and hot pressing. Fourier Transform Infrared Spectroscopy (FTIR) analysis revealed minor bond formations between the dyed fibers and polypropylene matrix in composites showing significant bonding at NH, CH, and OH regions. The composites containing dyed fibers showed slight improvements in tensile strength and modulus which is at best 2% than that of untreated fiber.Highlights Direct and basic dyes were determined as the most suitable synthetic dyes. FTIR analysis revealed minimal bond formation between the fiber and PP matrix. Composites having dyed banana fiber showed little better mechanical features.

Effect of olive-pruning fibres as reinforcements of alkali-activated cements based on electric arc furnace slag and biomass bottom ash

In this work, alkali-activated composites using electric arc furnace slag (50 wt%) and biomass bottom ash (50 wt%) were manufactured, adding olive-pruning fibres as reinforcement. The objective of adding fibres is to improve the flexural strength of composites, as well as to prevent the expansion of cracks as a result of shrinkage. For this reason, composites reinforced with olive-pruning fibres (0.5–2 wt%) untreated and treated with three different solutions to improve matrix–fibre adhesion were manufactured. Treatments developed over fibres were a 10 wt% Na2SiO3 solution, 3 wt% CaCl2 solution and 5 wt% NaOH solution. Mechanical properties, physical properties, thermal properties and the microstructure of composites by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) were studied to demonstrate the improvement. Alkaline treatment degraded fibre surface, increasing the matrix–fibre adhesion, and as a consequence, flexural strength increased up to 20% at 90 days of curing. Optimal results were obtained with composites reinforced with 1 wt% of olive-pruning fibre treated by a 10 wt% Na2SiO3 solution. Higher quantity of olive-pruning fibre leads to local agglomeration, which weakens the matrix–fibre adhesion. The effect on the compressive strength is less evident, since the addition of fibres produces an admissible decrease (between 0 and 9% using 0.5 or 1 wt% of fibres), except in composites that use olive pruning treated with 10 wt% Na2SiO3 solution, where values remain stable, similar or better to control paste. A greater ductility of the matrix in all composites was observed. Furthermore, the alkali-activated cement matrix was bonded to olive-pruning fibre better than untreated fibre, as it is shown in SEM images. Thus, the results showed that olive-pruning fibres could be used as reinforcement in the manufacturing of alkali-activated materials when they are treated with alkali solutions.

Surface modification of Luffa and Maize fibers by using alkali medium

Agricultural biomass is a well-known renewable resource that has a high rate of recycling. Two of them are luffa sponge and corn husk/maize fibers. Luffa sponge may be effectively used to reinforce lightweight composite constructions because of its polypore structure. For this race, maize fiber is also appropriate. Surface modifications for both of the fibers are needed for increasing mechanical strength with higher interfacial bonding with the matrix materials of composite manufacturing. This investigation involved treating both materials with 5 g/L, 10 g/L, and 15 g/L of NaOH in order to describe the alterations occurring on their physio-chemical characteristics. The therapy lasted 60 min and was administered at 90 °C. Following that, acetic acid was used to neutralize the samples. The ASTM D1445 technique was used to measure the bundle fibers' breaking force and elongation, and the ASTM D570 procedures were used in order to determine the water absorption variation % in the treated samples. The FTIR test and SEM examination revealed the contaminants that were eliminated from the surface of Luffa and Maize fibers. The test findings demonstrated improved modification behaviors for the 15 g m/L treated fibers, which had an elongation percentage of 3.02% and an equivalent breaking force of 5.12 kg for the Luffa fiber and 5.72 kg for the maize fiber. Natural contaminants were eliminated as a result of variations in functional group intensity shown in the FTIR pictures. However, SEM pictures showed that the surface smoothed out for samples treated with 15 g per liter of NaOH, which may be the cause of the fiber's brittle interlocking with the matrix components. Moreover, water absorbency rose by over 300% compared to the untreated fibers. In summary, samples treated with 10 g/L NaOH might serve as superior reinforced materials of composite for both types of fibers.

Mechanical and morphological analysis of cellulose extracted from sisal fibers and their effect on bio-based composites mechanical properties

This study aims to investigate the viability of untreated sisal fibers (N.F.), NaOH-treated sisal fibers (NaOH.F.) and cellulose extracted from sisal (CELL.F.) as an alternative to synthetic materials to produce biocomposites. The main objective was to conduct an in-depth study of the properties of these fibers whose aim is to limit matrix/fiber slippage and improve adhesion by modifying reinforcement surfaces, and to improve the efficiency of sisal fibers as reinforcements for composite materials using various analytical techniques including Fourier transform infrared spectroscopy, scanning electron microscopy, x-ray diffraction, and thermogravimetric analysis. In addition, the study aimed to produce a composite material by reinforcing plaster with the aforementioned fibers and then compare the mechanical and physical properties of the resulting material. The results showed that cellulose fibers exhibited higher mechanical strength and better compatibility with the plaster-matrix compared to sisal fibers by an increse of 324% in their tensil strength compared to natural sial fibers. In particular, the flexural strength showed a significant increase of 35% in the cellulose fiber reinforced composite. The reinforced composite material exhibited improved properties such as better flexural strength, increased absorption by 12.8% and descres the density by 21.3%, highlighting the promising prospects of cellulose fibers in advancing biocomposite technology.

Effect of hemp fibers and crystalline admixtures on the properties and self-healing efficiency of lime and clay-based mortars

This study investigates the impact of hemp fibers on two fiber-reinforced compositions, clay-based and lime-pozzolan mortar. Three compositions were prepared for each mortar, reference samples without fiber incorporation, samples with untreated hemp fibers, and samples with hydrothermally treated hemp fibers with crystallines. Crystalline admixtures (CAs) were incorporated into the hydrothermal pretreatment of fibers to promote the self-healing properties of the mortar when needed. Physico-mechanical and thermal properties took place to address the overall effect of hemp on the mortars. Adding hemp fibers enhanced the mechanical strength and reduced the mortars' shrinkage. The hydrothermally treated fibers have better cohesion with mortars, preserving the best results. To evaluate self-healing efficiency, pre-damaged cubic samples from each composition were subjected to tap water immersion for lime-pozzolan mortars and a controlled humid chamber for clay mortars after a curing period. The healing rate was assessed by measuring crack closure, compressive strength recovery, and the dynamic modulus of elasticity recovery. The results indicated significant strength recovery in lime-pozzolan mortars with hemp fibers. Clay-based mortars showed moderate strength increases and limited self-healing.

Techno-Environmental Evaluation of Alkaline Treatment in Flax Reinforced Thermoplastics.

A combination of thermoplastics and natural fiber reinforcements is considered an ideal choice to mitigate environmental impacts and enhance recyclability or reusability. Chemical treatments are often employed to enhance the thermomechanical properties of natural fiber-reinforced plastics. Nevertheless, it is of paramount importance to assess the techno-economic impact of such chemical treatments and environmentally friendly materials for their implementation in mass productions on an industrial scale. In this work, high-density polyethylene is reinforced with sodium hydroxide (NaOH)-treated and untreated flax fibers to study its impact on mechanical and environmental properties. The composites treated with NaOH exhibited a 37% increase in tensile strength. However, life cycle assessment performed on the NaOH-treated samples showed that they had a global warming potential of 5.8 kg of CO2, a terrestrial acidification potential of 0.0269 kg of SO2, and a human carcinogenic toxicity of 0.031 kg of 1,4-DCB compared to the untreated samples. In summary, the techno-environmental analysis reveals a novel approach to identifying chemical treatments based on their technical and environmental effects.

DEFLECTION AND STRAINS PERFORMANCE OF KENAF FIBRE-REINFORCED CONCRETE BEAMS

There has been a need to find a lasting means to improve beams' deflection and strain performance without necessarily increasing the beam stirrups. The limitations of steel and other synthetic fibres have reduced their application. Given its tensile strength, renewability, sustainability, and affordability compared to steel and synthetic fibres, kenaf fibre development is of great interest in Malaysia. Therefore, this research work experimentally investigated the deflection and strain performance of Kenaf Fibre Reinforced concrete beams. The volume and length of kenaf fibre used were 0.75% and 25mm, respectively. Kenaf fibre was treated with 5% NaOH to improve its performance. The alkaline-treated and untreated kenaf fibres morphology was observed under a variable-pressure scanning electron microscope. It was discovered inclusion of kenaf fibre reduced the workability of concrete. Also, plain and KFR concrete morphology was observed under a variable-pressure scanning electron microscope. Four beams were designed to study the deflection and strain performance of the KFR concrete beam; one was well reinforced but without kenaf fibre. The stirrups spacings were increased by 25%, 50%, and 75% for the other three beams. The beams were tested under centre loading. Deflection and concrete strain at the centre and along the beam span were measured using LVDTs and concrete strain gauges for the four beams. Furthermore, the strains on the shear and bottom flexural reinforcements at the centre of the beam were measured using steel strain gauges. It was discovered that kenaf fibre enhanced the deflection and strain performance of beams between 25% and 50% stirrups deficiency.

Gypsum reinforced using hemp fibers: Enhanced interfacial compatibility by dual-modification strategy

Natural fibers are promising as enhancements for gypsum. Herein, the effect of using untreated, NaOH-modified, and dual-modified hemp fibers on enhancing performances of gypsum composites is examined. The dual-modification strategy applies secondary treatment on NaOH-treated fibers with NaClO, polyoxyethylene, or Tween-80. The fibers and composites are characterized by SEM, ATR-FTIR, XRD, mechanical strength, etc. The secondary modification enhances interfacial compatibility between gypsum and fibers. Compared with pure gypsum, the elastic modulus and bending strength of the composites with dual-modified fibers increase by 56% and 42%, respectively. Hydration process reveals that dual-modification using polyoxyethylene contributes to form dense, compact composite structures.

An inquisition on alkaline treated Banana/Sisal/Pineapple fiber epoxy composites for light to moderate load applications

To address the sustainable development goals, an attempt was made to investigate the alkaline treated and untreated Banana, Sisal, and Pineapple fiber epoxy hybrid composite for their mechanical and thermal properties. Tensile, Flexural, Impact, modulus, and Heat Deflection temperature (HDT) were evaluated and analyzed for low-load structural applications.

Interfacial failure analysis was also carried out with the help of a Scanning Electron Microscope (SEM) to study the microstructural behavior of the tested specimens. It was observed that the alkaline treatment increases fiber-matrix interaction.

Preparation of gallic acid-polydimethylsiloxane codeposited carbon fibers to improve interfacial properties of epoxy composites

A novel method, drawing inspiration from the chemistry principle observed in mussels, has been recently developed to augment the wettability and adherence of carbon fibers (CFs) within epoxy resin matrix. This technique entails the concurrent application of gallic acid and aminopropyl double terminated polydimethylsiloxane on CF surfaces via a direct method. Advanced analytical techniques like scanning electron microscopy, X-ray diffraction, infrared and Raman spectroscopy, along with X-ray photoelectron spectroscopy, confirmed the effective simultaneous deposition of these agents, possibly via Michael addition or Schiff base reactions. Incorporation of these treated fibers into epoxy composites resulted in notable performance enhancements. The composites with gallic acid and polydimethylsiloxane modified fibers exhibited up to 14%, 13%, and 27% improvements in interlaminar shear strength, flexural modulus, and flexural strength, respectively, compared to their counterpart with untreated fibers. These results indicate that combining gallic acid and polydimethylsiloxane on CFs is a potent approach to boost the interface qualities of CF-reinforced epoxy resin composites.

It has been seen form compression test that palm composite has never been higher compressive strength than the control mix.

Nano-clay treatment of jute fiber for reinforcement in polymer composites: Mechanical, morphological, and thermo-kinetic analysis

Natural fibers have demonstrated exceptional properties that can be utilized as a viable and environmentally reliable material for reinforcement in polymer composites replacing their synthetic counterparts creating numerous environmental problems. Jute fiber is a prominent natural fiber that has been successfully applied for manufacturing noble natural fiber-based composites. This article describes the advantages and comparison between two surface treatment techniques that is alkali treatment and nano-clay treatment of jute fiber to enhance the properties for producing improved composite material. FTIR, SEM, AFM, and TGA have been utilized to compare and study how different surface treatment methods affect jute fiber. Isoconversional methods FWO and KAS are applied for the thermos-kinetic analysis and evaluation of activation energy of thermal decomposition. More than 30% increase in peak activation energy has been observed (120 KJ/mole to 160 KJ/mol). Alkali–nano-clay treated jute fiber exhibits nearly 32% improvement (405 MPa to 535 MPa) in tensile strength, 24% increment (11.85 GPa to 14.69 GPa) in tensile modulus, and 15% improvement (1.4 gm/cm3 to 1.61 gm/cm3) in fiber density as compared to that of untreated jute fiber. This study validates that nano-clay treatment has shown promising results and can improve the overall properties of natural fibers significantly.
