Resistance to crack propagation of a composite with recycled jute fabric – Polypropylene

This study investigates the mechanical properties of PP/jute fabric laminates in different weave configurations (Satin, Serge 2x2, and Taffetas), focusing on toughness, stress intensity, energy restitution rate, and fracture energies. The results show a narrow toughness range (2.9 to 3.7 MPa.m1/2) across configurations. Stress intensity factor peaks at 6 MPa.m1/2 for three composites, with one (Bio-Com B) reaching 8.5 MPa.m1/2. Energy restitution rate increases with crack growth, with Bio-Com B exceeding others at 24 kJ/m2. Fracture energy trends are consistent across materials, with weave having a notable influence on properties beyond a specific crack growth value. The study highlights the significant effect of reinforcement architecture on laminate mechanical properties, especially in fracture energy and crack growth resistance. It concludes that recycled jute/PP composites offer promising, sustainable alternatives for furniture and construction due to their superior cracking resistance and environmental benefits.

Biocomposites of Epoxy and Natural Fiber: A Study of Their Micromechanical Properties

As agricultural biomass, Inula Viscosa Fiber (IVF) is one of the valuable natural fibers that is widely accessible in M'sila, Algeria. The aim of this study is to investigate the effects of alkali (NaOH) (3%) and potassium permanganate (KMnO4) (1%) on the physical and mechanical properties of IVF to enhance the interfacial bonding of IVF with thermosetting epoxy matrices (TE). The efficacy of the alkali and potassium permanganate treatments in eliminating impurities was studied using scanning electron microscopy and Fourier transform infrared spectroscopy. Compared to both alkaline and untreated IVF, permanganate-treated IVF shows superior tensile strength. The droplet test indicates that the interfacial stress resistance (IFSS) of alkali and permanganate-treated IVF is improved, while potassium permanganate-treated fibers show the highest IFSS. From this result, the higher interfacial shear strength was permanganate-treated fiber with 4.50 MPa, followed by alkaline treatment, and untreated of IVs fiber with 3.36 MPa and 2.93 MPa, respectively. Fiber treatments are thought to contribute to the creation of industrially useful, high-performance IVF-reinforced polymer composites.

Effect of alkali treatment on new lignocellulosic fibres from the stem of the Aster squamatus plant

This research aims to examine the physical, structural and chemical properties of Aster Squamatus (AS) fibres, which are commonly found in Algeria, Brazil, France and the West Indies. In this work, we assess their appropriateness as reinforcing fillers to fabricate components for polymer composites principally designed for lightweight applications. To accomplish this objective, an extraction of fibres from plants modification of AS fibres and characterization of both untreated fibres (UASFs) and alkali-treated AS fibres (TASFs) are conducted. We analysed the crystallinity, chemical composition, thermal characteristics, and mechanical properties of AS fibres as per standard methods. It's clear from chemical treatment that amorphous components were successfully eliminated from the AS fibres, including hemicellulose, lignin, and wax. Consequently, the fibres' thermal, physical, and mechanical characteristics including Young's modulus, tensile strength, crystalline index, and surface roughness were substantially enhanced. It was determined that the fibres possessed a thermal stability of around 250 °C, with the maximal degradation temperature rising from 372.50 to 375.35 °C. The maximum stress rose from 183.24 ± 25.27 to 302.00 ± 24.91 MPa, the Young's modulus increased from 11.08 ± 1.1 to 18.53 ± 1.45 GPa, and the crystallinity index increased from 43% to 45%. Two-parameter Weibull statistics showed a strong link between experimental data and mechanical features of the twenty samples. We concluded from this work that AS plant fibres can serve as a robust reinforcing material in polymer composites for various applications.

Numerical Investigation of the Impact of Temperature on a-Si and GaAs/a-Si Semiconductor Solar Cells

There is a pressing need for investigations of solar conversion systems to enhance and perfect the use of this expandable energy resource. This necessitates additional research on the development of solar cells, which are the mainstay of these systems. In this regard, the purpose of this study is to examine, using numerical modeling, the impact of cell temperatures in the range of 270–340 K on solar cell performance and efficiency. Two configurations are considered based on different overlapping materials. A solar cell type ZnO/a-Si(n)/a-Si(p) (single-junction) with thickness of 25 nm, 50 nm, and 2500 nm, respectively, and a solar cell type ZnO/GaAs(p)/a-Si(n)/a-Si(p) (double-junction) with thickness of 25 nm, 100 nm, 50 nm, and 2500 nm, respectively, are examined. The electrical characteristics, fill factor (FF), and efficiency (ɳ) are extracted to highlight the results of the present study. Numerical analysis was performed using AMPS-1D (One-Dimensional Device Simulation for Analysis of Microelectronic and Photonic Structures), a modeling and analysis program. This analysis enabled the establishment of a causal relationship between the features of the considered solar cells and their corresponding material attributes, and the production process.

Delamination behavior of a bidirectional composite with vegetable fibe

Composite materials must meet the requirements of imposed mechanical stresses through the judicious choice of reinforcements and matrix. The use of composite materials in specific fields (aeronautics, automotive, aerospace, insulation, etc.), represents a significant advantage as we can design a composite material that meets the requirements of the stresses. The goal of our work is to study the delamination behavior of a bidirectional composite with vegetable fibers. This study is conducted by determining the mechanical characteristics of these materials from tensile tests and analyzing mode I fracture through delamination tests of several samples differentiated by a pre-defect. These tests are aimed at determining the energy restitution rate and then the R-curves (resistance curve). The material used is a composite material with a polymeric matrix and vegetable fibers. The matrix is an unsaturated polyester, and the reinforcement is a jute fabric combined with glass fibers developed within the Non-Metallic Materials Laboratory (L.M.N.M) (University of Sétif -1-). Different types of plates with different interfaces are elaborated.

The impact of physicochemical treatments on the characteristics of Ampelodesmos mauritanicus plant fibers

The utilization of cellulosic fibers is becoming increasingly widespread worldwide as promising raw material in polymer composite reinforcement. However, and despite the multiple advantages of cellulosic fibers like the lower density, cheap cost and biodegradability, their use is limited due to hydrophilic character which reduces their affinity with hydrophobic matrices. A natural fiber treatment, whether chemical or physical, is advised to address this issue. The purpose of this study is to characterize the Ampelodesmos mauritanicus plant (AM) fibers extracted by the chemical method (2% NaOH for 48 h) and treated (chemically and physically). We carried out acetylation, mercerization and microwaves modification of the AM plant fibers to reduce their hydrophilic character. The influence of chemical and physical treatments on the structure and morphology of AM plant fibers was characterized by analytical techniques as per International Standard. X-ray diffraction confirmed that the AM fibers have a good crystallinity index (52.4%). Microwave physical treatment at 550 W increased their density from 1.00 to 1.55 g/cm3, their Young’s modulus and tensile strength from 11.0 to 18.6 GPa and from 155 to 290 MPa, respectively, giving the highest values. It is followed by chemical treatments: first with acetic anhydride (C4H6O3) for 4 h and then with 3% NaOH also for 4 h. It should be observed that the data have a very considerable dispersion that calls for statistical analysis (method of Weibull with two and three parameters was utilized).

New cellulosic fibre from Spathes of male date for lightweight composite materials: extraction and characterization

Researchers and industry are looking for green and sustainable materials as reinforcement for lightweight composite structures. This research aim was designed to study the characteristics of the fibre extracted from a waste product of the spathe of date palm (SDP). In this work, density, crystallinity index, crystal size, tensile strength, surface roughness, extreme degradation temperature and thermal stability of SDP fibres were investigated. Density is estimated to be 0.59 g/cm3. X-ray diffraction analysis indicated the crystallinity index about (57.82%) and the crystal size is (19 nm). The results of the thermal analysis gave the degradation temperature as 270 °C and Ea as 69.14 kJ/mol. Scanning electron microscopy (SEM) investigation confirmed the presence of surface contaminants including wax and other foreign materials. Also, the mechanical properties identified are tensile strength (100 ± 21.5 MPa), and Young's modulus (4 ± 0.9% GPa). Based on the study's findings, SDP fibres should be considered for usage as a reinforcing material in the development of novel polymer composites with a wide range of lightweight industrial applications.

Ce travail a pour but de contribuer à réduire les impacts environnementaux à travers l’élaboration de composites avec des matériaux recyclables pour être utilisés dans différentes
applications. A cette fin, des composites ont été développés à base de jute récupéré à partir de sacs d'emballage et de polypropylène (PP) récupéré à partir de déchets obtenus lors de la fabrication de fils de PP. Les composites développés ont ensuite été caractérisés.
Tout d'abord, la fraction massique optimale a été déterminée afin d'obtenir de bonnes performances mécaniques. Plusieurs fractions massique (30%, 40%, 45%, 50%, 60%, et
70%) ont été expérimentées, les meilleures caractéristiques étaient celles du biocomposite avec un taux de renforcement de 40% (σ = 39,07 MPa, E = 4,60 GPa). Avec ce
pourcentage, des biocomposites jute-PP ont été élaborés avec différentes architectures de jute (Satin, Serge2x2, Taffetas). Une étude structurelle des différents déchets de tissus de jute a
été réalisée pour confirmer s'ils sont adaptés à une utilisation avec une matrice thermoplastique (c'est-à-dire, à une température de fabrication de ≥ 200C). Des essais de
traction ont été effectués sur ces composites afin de connaître l'effet de la structure de tissage du renforcement.

Extraction and characterization of fiber treatment Inula viscosa fibers as potential polymer composite reinforcement

This research aims to characterize and analysis of newly cellulosic fiber extracted from Inula viscosa bark. The obtained Inula viscosa fibers were also characterized after having been treated with alkali and permanganate treatments. The effect of chemical treatments on the mechanical, physical, chemical and thermal properties of Inula viscosa fibers was investigated by using, X-ray diffraction, thermo gravimetric, scanning electron microscope analysis, optical microscope test, tensile and droplet tests. The treatment with permanganate was found to have the higher density (1.154 ± 0.032 g/cm3) compared to that of the untreated ones (1.040 ± 0.010 g/cm3). The best mechanical properties were also achieved when the permanganate treatment was adopted. In this pretext, tensile strength values and Young modulus were found as 196.99 ± 28.89 MPa and 12.98 ± 2.36 GPa, respectively. It is estimated that the fiber treatments will enable high-quality Inula Viscosa Fiber-reinforced polymer composites for use in the industry.

Characterization of physical and mechanical properties of recycled jute fabric reinforced polypropylene composites

This research designed to contribute to reduce the environmental impacts through the preparation of composites with recyclable materials to be used in different applications. To this end, composites have been developed based on jute recovered from packaging bags and polypropylene (PP) reclaimed from scraps obtained from the manufacture of PP yarns. The developed composites were then characterized. First of all, the optimum mass fraction was determined in order to achieve good mechanical performance. Several mass fractions (30%, 40%, 45%, 50%, 60%, and 70%) were experimented to find that the best characteristics were those of the biocomposite with 40% reinforcement (σ = 39.07 MPa, E = 4.60 GPa). With this ratio, jute–PP biocomposites were further developed with different jute architectures (Satin, Serge 2 × 2, Taffeta). A structural study of the different jute fabric wastes was carried out to confirm whether they are suitable for use with a thermoplastic matrix (i.e., at a processing temperature of ≥200°C). Tensile and bending tests were carried out on these composites to find out the effect of the weave structure of the reinforcement.
