This work aims to optimize the physicochemical and tensile properties of vascular fibers extracted from a local date palm rachis in Algeria. fiber has very specific composition architecture is different remaining obtained six possible parts tree. For this purpose, Taguchi orthogonal array design L16 was applied reduce number experiments. The were with two methods (boiling retting water) treated by NaOH various concentrations (1%, 2%, 3%, 5%) for durations (1, 4, 8, 12 h). They characterized...
This study focuses on the chemical and thermo-physical characterization of date palm fiber, which can be used in reinforcement green composites. Alkaline solutions with different concentrations NaOH (0.5, 1, 2 3%) various immersion times 2, 4, 6 8h) at room temperature were to treat fibers obtained from fruit branches. In total, 750 samples tested, results show that treatment lead an increase, up 3 times, their mechanical properties (strength Young's modulus) quasi-static tensile tests. Due...
Natural fibres have many advantages over synthetic ones, making them attractive for reinforcing polymer materials. This work evaluates the use of an Amazonian plant, namely Curauá (Ananas erectifolius), as a reinforcement phase biocomposites fabricated by cold pressing. been shown to be promising fibre composite materials, especially due their higher elastic modulus than other plant species. An L9 Taguchi design is used investigate effect fraction, NaOH concentration and immersion time on...

Abstract This work describes the effect that stacking sequence lay‐ups have on static and cyclic fatigue properties of T300/914 auxetic carbon/epoxy composites. Two laminate composites [±20] 2S [±25] providing a theoretical NPR through thickness been subjected to quasi‐static under 3‐point bending. The tests shown stiffness maximum failure load decrease with increasing fibre orientation angles for laminates. also show degradations versus number cycles occur tree stages, significant energy...
Natural fibre reinforced polymer biocomposites (NFPBCs) constitute an important branch in the field of green composite materials. The work describes fatigue behaviour polyester with natural sisal fibres and stacked as cross laminates [0/90]s sequence Three-point bending static cyclic tests have been used to investigate these particular bio-reinforced composites. carried out at 1.5 Hz frequency using a sinusoidal waveform loading levels varying between rd = 0.55 0.95 curves stiffness...
Abstract This study investigates the incorporation of date palm fibers, an abundant agricultural waste, into polyvinyl chloride (PVC) composites at a 25% fiber weight ratio. Alkali treatment, potassium permanganate oxidation, and silane coupling were applied to enhance fiber‐matrix adhesion. The fabricated using hot pressing method. results revealed significant improvements in mechanical, thermal, moisture resistance properties for treated fibers compared untreated ones. Potassium treatment...
Abstract The variation of through‐thickness Poisson's ratio with fibre type and orientation has been investigated using a specially developed Fortran program. Glass fibre/epoxy resin composites were always found to be conventional, but negative values up ν 13 = –0.746 produced over certain angles for Kevlar carbon reinforcements. This underlines the need anisotropic pre‐preg material. A range [± β /± θ ] s laminates it was that auxetic behaviour could generated 45°. All findings this work...
