Addition of ammonium polyphosphate for simultaneous enhancement of flame retardancy, mechanical, and viscoelastic properties of PALF‐reinforced bio‐HDPE composite

AbstractThis work is focused on reducing the flammability of 25 wt.% pineapple leaf fiber (PALF)‐reinforced bio‐based high‐density polyethylene (bio‐HDPE) composites. Varying contents of ammonium polyphosphate (APP) up to 10 wt.%, have been incorporated as a flame retardant while its effects on mechanical and viscoelastic properties are also evaluated. The linear burning rate is reduced by up to 26% for 10% APP content in the horizontal burn test. The incorporation of APP also proved beneficial in arresting the dripping of the polymer matrix during the vertical burn test. Thermal analysis showed that the interaction between APP and natural fibers enhanced the residual char content by up to 9%. Furthermore, dynamic mechanical analysis revealed an increase in the damping factor (loss tangent) with APP addition. The findings recommend incorporating up to 5% APP in PALF/Bio‐HDPE composites as optimum. PALF‐reinforced Bio‐HDPE composite with improved flame retardancy, mechanical, and damping properties is achieved, offering an alternative to conventional composites used in automobile and construction industries.Highlights Flame‐retardant composites made from 25% PALF and 10% APP. 10% APP base composite showed a 26% reduced UL 94 horizontal burning rate. APP incorporation increases residual char content and prevents dripping also. APP enhances both the mechanical properties and damping factor of composites.

Mechanical Traction Test of Pineapple Leaf Fiber-Epoxy Composite

Natural fiber-based composites are widely developed to replace materials in various industries, such as furniture and sound absorbers. One of the composite properties that is often considered for its use is mechanical property. In this study, the mechanical properties of pineapple leaf fiber-epoxy composites were studied using traction tests. The composite was made by mixing of small pieces of pineapple leaf fiber with epoxy resin, then the mixture was placed in a mold and pressed with a certain pressure at 100 °C for 2 hours. Traction tests were carried out on the pineapple leaf fiber-epoxy composites with two different epoxy concentrations (11 and 17 % wt), and different manufacturing pressure (0.22; 0.65; 1.09 MPa). The traction test results show that the maximum stress (ultimate tensile strength/UTS), elongation at break (EAB) and modulus of elasticity (E) increase with increasing epoxy content. Increasing the manufacturing pressure increases modulus of elasticity. However, the maximum UTS and EAB were shown by the composite with a manufacturing pressure of 0.65 Pa, not at the higher pressure (1.09 Pa).

Effect of the carding process and fibre length on the properties of pineapple leaf fibre and reinforced polypropylene composites

In this work, a greener approach, the carding process, was used to remove extraneous materials from the surface of pineapple leaf fibre (PALF) instead of using conventional chemical treatments. PALF was cut into three lengths and processed using a carding machine for different numbers of passages. Carded PALF and polypropylene (PP) fibres were then blended uniformly at 50% weight percentage through the carding process. The mixed fibres were further processed by a gill-drawing machine to produce oriented PALF-PP silvers, which were consolidated in a compression moulding machine to fabricate the unidirectional composites. The experimental results indicated that the increase in the number of carding passages and PALF cut-length increased the surface fibrillation, roughness and crystallinity, and reduced the water contact angle (i.e., increased hydrophilicity) of carded PALF. The thermal insulation performance of the composites improved in cases of shorter PALF length after five carding passages and coarser PP fibres, but at the same time, the water absorbency also increased, indicating reduced water resistance of such composites.

Progress in Biomass-Based Electrospun Nanofibers in Bio-Medical Application

Traditional biomedical applications in wound dressing and tissue engineering materials frequently lack the appropriate balance of environmental friendliness, antibacterial effectiveness, and mechanical strength. A growing number of medical applications are focusing on electrospun nanofibers because of their special qualities, which include a high surface area-to-volume ratio, tailor-made mechanical strength and more eco-friendly. The goal of this review paper is to thoroughly examine the corpus of research that is currently available about electrospun, nanofibers especially made from aloe vera and pineapple leaf fibers for use in biomedical applications. This review's goals include optimizing electrospinning conditions, assessing biocompatibility, researching antibacterial activity, and its current challenge.

The toughness of polymer reinforced pineapple-leaf fibers for the electric car body application

Abstract Pineapple-leaf fiber (PALF) belongs to the plant-based fiber group that has been highly abundant recently. However, PALF was no longer used and thrown away as agricultural waste. In fact, PALF can be used as alternative reinforcement for composite materials due to its properties. Composite materials have been used in the aircraft, automotive and household furniture industries. The objective of this research was to investigate the impact properties of epoxy resin matrix reinforced with glass fiber and PALF. The ASTM D256-23 standard was carried out when performing the impact test. The result showed that the composite material consists of PALF had higher impact strength compared to the composite reinforced by glass fiber. The compatibilities of fiber and matrix became main factor that affect significantly the value. This was confirmed by the porosities test results. Therefore, PALF was proven its reliability to substitute the synthetic one such as glass fiber to strengthening the composite materials for electric vehicle body application.

Determination of Significant Factors and Optimum Condition for Pineapple Leaf Fiber Extraction as Potential Dielectric Material

The aim in this study was to evaluate the most significant factor affecting the extraction of pineapple leaf fibers and to optimize the extraction conditions. The selected four factors of pineapple leaf powder mass, pineapple leaves to distilled water ratio, pulping time, and heating option were analyzed through two-level factorial analysis via Design-Expert software. The optimum conditions were determined using central composite design (CCD) of response surface methodology (RSM). The extracted fibers were analyzed through the Kurschner-Hanack method for cellulose content and were used to produce dielectric materials. The permittivity value of the developed dielectric material was measured through an Agilent vector network analyzer (VNA). The best condition was obtained with a heated sample at 3 g pineapple leaf powder mass, 1:10 PL: DW, and 49.24 min pulping time, which produced 59.25% cellulose content and 2.89 permittivity value. The optimum condition was achieved at 50 min of pulping time and 1000 mL water with 46.84% cellulose content and 2.97 permittivity value. Therefore, based the obtained permittivity value, pineapple leaves could be further explored as potential dielectric materials.

Mechanical behaviour of pineapple leaf fibers reinforced Lapox L-12 epoxy composites

To meet the increasing need for composites in sectors such as medical, transportation, safety, and athletics, researchers continuously develop novel composites. This study investigated the effects of boron carbide filler particles in epoxy by fabricating composites from Lapox L-12 epoxy with 20 and 30 wt. % of pineapple leaf fibres (PALF) utilising the hand layup method. The mechanical parameters of the synthesised composites were evaluated according to ASTM standards, encompassing hardness, ultimate tensile strength, yield strength, elongation, and flexural strength. The addition of pineapple leaf fibres to epoxy Lapox L-12 resulted in enhanced hardness, tensile strength, and flexural strength, accompanied by a minor reduction in percentage elongation. Lapox L-12 composites supplemented with 30 wt.% of PALF exhibited enhancements of 60.8% in hardness, 66.2% in ultimate strength, and 101% in flexural strength.

Investigating the Impact of Physical and Mechanical Characteristics of Palf/Glass Fiber Reinforced In Epoxy Resin

Recent times, the nature fibers deepen its roots in the field of composite materials. Owing to its ecofriendly characteristics, the natural fibers had its upper hand to the synthetic fiber. But, usage of natural fiber alone doesn’t bring desirable characteristics to the fabricated material. Therefore, the amalgamation of synthetic and natural fiber as the reinforcement in the polymer composite brings desirable property to the newly fabricating material. In this paper, we utilized the Pineapple Leaf Fiber (PALF) and glass fiber as the reinforcement in the epoxy resin and fabricated the new material. The paper mainly concentrates to study the physical and mechanical characteristics of the material. The uniform distribution of PALF and glass fiber over the polymer matrix was confirmed with the help of images of Scanning Electron Microscope (SEM). The PALF and glass fiber of composition of 20 % and 15% of weight ratio shows significant resistance to brittleness and have high tensile strength. Consecutively, the PALF and glass fiber of composition of 25% and 10% of weight ratio yields higher bending strength and shows implacable resistance to compression and impact load.

AbstractThe study aims to investigate and find natural fiber as concrete reinforcement using the self-compacting concrete method. Methods of adding fiber and self-compacting concrete methods are exciting because these two methods have different characteristics and advantages. Therefore, the performance of the fresh-state flow capability of the self-compacting concrete method, which contains various fibers, was observed. Coconut fiber, pineapple leaf fiber, ijuk sugar palm fiber, and artificial polypropylene fiber were used with varying compositions of 0.3, 0.5, and 0.7% by mass of binder. The results show that coconut and pineapple fiber concrete met the European Guidelines for Self-Compacting Concrete standards. The coconut and pineapple fiber concrete performed admirably in all tests.

Preparation and characterization of carboxymethyl microcrystalline cellulose from pineapple leaf fibre

Highly functional and robust biobased materials are still in research to produce valuable composites for various applications. The literature shows the gap of new raw biobased materials in market which can functionally tuned and structurally modified for development of 2d/3d architectures. Thus, in the present study, very cheap, easily available agricultural waste, pineapple leaf fiber (PL-raw) was used for the isolation of microcrystalline cellulose (PL-MCC) and further functionalized using upscaled chemical approach to carboxymethyl microcrystalline cellulose (PL-CMMCC). Very advanced techniques like Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), X-ray diffraction analysis (XRD), and differential scanning calorimetry (DSC) served to characterize the raw material, high crystalline PL-MCC, and modified carboxy methyl MCC. FTIR determined presence of different absorbed peak at approximately 1620.2 cm−1, and at 1423.8 cm−1, carboxyl groups were assigned to PL-CMMCC. On the other hand, the XRD findings verified that PL-CMMCC’s crystalline structure has decreased. Analysis by SEM revealed a damaged surface morphology for PL-CMMCC. Following chemical treatments, the EDX analysis revealed that each fiber sample contained a highly pure cellulose elemental composition. Thus, results explain the utilization of agricultural waste, pineapple leaf fiber to high valuable products like highly crystalline PL-MCC, in addition further modification of PL-MCC could leads to formation of highly functional material that could be used for other applications too in future.

Facile fabrication of 3D-printed cellulosic fiber/polylactic acid composites as low-cost and sustainable acoustic panels

This work presents a green, cost-effective and eco-friendly strategy to reduce noise pollution by developing biopolymer-based 3D-printed acoustic panels. We successfully fabricated two series of composites by varying the weight percentage (wt%) of cellulose fibers of water hyacinth (WH) and pineapple leaf (PAL), with polylactic acid (PLA) as the matrix via the heat-press method. All samples were characterized using Fourier transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and scanning electron microscopy (SEM). Physico-mechanical properties, including hardness, tensile, and impact strength, were improved with increasing fiber loading. Filaments of 1 wt% water hyacinth fibers (WHFs) in PLA (1 WHF/PLA) and 1 wt% pineapple leaf fibers (PALFs) in PLA (1 PALF/PLA) were prepared and tested for 3D printability. The sound absorption coefficients (α) of the 3D-printed panels were investigated from 500 to 5000 Hz sound frequency range. The 3D-printed 1 WHF/PLA and 1 PALF/PLA acoustic panels achieve a maximum α (α-max) of 0.55 and 0.83 at 5000 and 4000 Hz, respectively, featuring the first work to report α-max > 0.5 at low fiber loadings in the high-frequency sound range. The tensile strength of the 3D-printed versions is significantly higher than non-3D-printed counterparts and commercial acoustic absorbers. Our data suggest the prepared 3D-printed panels are excellent candidates for acoustic applications at high-frequency noises. This study exhibits a facile, environmentally benign and sustainable approach to construct highly efficient and mechanically robust biopolymer-based 3D-printed sound-proof panels, which have promising potential as green engineering materials. Interestingly, this research also proposes a mitigation technology for the freshwater invader, Eichhornia crassipes (water hyacinths).

Effect of Mercerization on the Properties of Cellulose Fiber and Cellulose Hydrogel Extracted from Pineapple Leaf Fiber

AbstractThis study investigated the effects of alkaline treatment on the pineapple leaf fiber (PALF) cellulose extraction and the properties of cellulose hydrogel. PALF was treated with different concentrations of sodium hydroxide (NaOH) (2 to 10 wt %) and at room temperature (RT) and 80 °C. Then, extracted cellulose was then dissolved in N,N’‐dimethyl acetamide (DMAc)/lithium chloride (LiCl) solvent system and formed into hydrogel by phase inversion method. The Fourier transform infrared spectra shows the peak disappearance at 1606 cm−1 proves that lignin was removed starting from 6 and 4 wt % NaOH at RT and 80 °C, respectively. Higher NaOH concentrations treatment increased thermal stability and the crystallinity (71 to 79 %) of the fibers. Higher NaOH concentration and treatment temperature enhanced cellulose extraction from PALF, leading to more physical crosslinking during hydrogel formation. High amount of cellulose extracted decreased the hydrogel's swelling equilibrium and increased the gel fraction. The highest transmittance (87.8 %) and the lowest intensity of absorbance (at 280 nm corresponding to lignin) were obtained by the hydrogel prepared with PALF treated with 8 wt % NaOH at 80 °C. Clearly, this research findings provide new insights into optimizing cellulose extraction using alkaline treatment specifically for cellulose hydrogel formation.

The Effect of Areca Nut Fiber and Pineapple Leaf Fibers and Polyester Composition on Mechanical Properties of Composite Diva Akbar*, Dody Yulianto Mechanical Engineering Study Program, Faculty of Engineering, Islamic University of Riau Jl. Kaharuddin Nasution Km 11 No.113 Perhentian Marpoyan, Pekanbaru Telp. 0761 – 674635 Fax. (0761) 674834 Email : divaakbar@student.uir.ac.id ABSTRACT Areca nut fiber and pineapple leaf fiber are types of fiber derived from natural fibers that are interesting to research as composite reinforcing fibers because currently they are very abundantly available. This research aims to make composite boards made from areca nut fiber and pineapple leaf fiber with polyester resin metrics for mechanical strength. This research varied different mixtures starting from areca nut fiber: pineapple leaf fiber: polyester resin, namely 20%: 30%: 50%, 25%: 25%: 50%, 30%: 20%: 50% using The hand lay up method was carried out three times in making composite board specimens. The highest bending strength results in sample one with a mixture of 20% areca nut fiber, 30% pineapple leaf fiber and 50% polyester resin were 52.60 Mpa, the impact value was 0.379 Joules/mm2. This is because there is the influence of the fiber and metric mixture which causes the elasticity modulus value to increase and because there is the influence of fiber density, where the smaller the density value the greater the mechanical strength, both bending strength and impact value. This phenomenon can be seen from macro observations, namely that composite boards experience fiber pull out with a fibrous brittle fracture type.

Physical, Mechanical and Thermal Characterization of Areca, Pineapple and Glass Fiber Reinforced Polymer Composites for Aerospace Applications

In the current scenario, the focus on applying natural fiber-reinforced polymer composites in aerospace applications has increased tremendously due to their attractive characteristics such as lightweight, higher strength-to-weight ratio, good thermal stability at environmental temperatures, resistance to corrosion, sound absorbing capability and increased fuel efficiency. Further, studies on Bi-directionally oriented fiber composites have more advantages than the random or unidirectional orientation, such as uniform stress distribution and improved bonding at the interface. So, the present work focuses on using the Areca, Pineapple Leaf Fiber (PALF) and Glass fiber as the bi-directional fiber mat for reinforcing it into Epoxy polymer. The three different materials were fabricated by changing the fiber type with constant volume fraction and orientation. The martial characterization was done on the fabricated composites in order to evaluate their orientation effectiveness through density, moisture absorption, tensile, impact, hardness and thermal degradation. The bonding relationship was analyzed through a Scanning Electron Microscope. The results showed that the properties obtained were higher for the PALF composite than the areca composites due to the fact that the higher surface area of PALF fibers is confirmed through SEM analysis.

Influences of hybrid fiber on functional and drilling characteristics study of polymer hybrid Nanocomposite

The severe environmental pollution related to the manufacturing, recycling and disposal of metal-based and synthetic fiber-based composites has a major impact on human and animal life. A wide range of studies are conducted on alternative materials in order to reduce greenhouse gas emissions. Various industries are focusing on using natural fibers from banana, jute, coir, hemp, pineapple, areca, kenaf, Sterculia foetida and Delonix regia that are the key sources of different components for developing nanocomposites. Drilling is a vital factor in the assembly process of composites. The amorphous structure of the natural fibers causes the formation of cracks at the entry and exit sides of the drilled hole. So, in the present work a nanocomposite was synthesized and optimized the machining parameters, which affect the surface finish of the hole at the entry, exit and inner surface of the drilled hole. The effect of the hybridization of glass fiber with the pineapple leaf fiber and areca fiber was studied in terms of tensile properties, delamination around the hole and surface roughness. The microstructure of the holes was studied by Scanning Electron Microscopy.
