The experimental design and response surface methodology (RSM) have been used to develop predictive models for simulation and optimization of electrospun polyvinylidene fluoride non-woven membranes. The objective is to prepare electrospun fibers with small diameters and narrow diameter distribution. The factors considered for experimental design were the polymer dope solution flow rate, the app...

A 3D microstructure of the non-woven gas diffusion layers (GDLs) of polymer electrolyte fuel cells (PEFCs) is reconstructed using a stochastic method. For a commercial GDL, due to the planar orientation of the fibers in the GDL, 2D SEM image of the GDL surface is used to estimate the orientation of the carbon fibers in the domain. Two more microstructures with different fiber orientations are g...

Biocomposites based on poly(L-lactic acid) (PLA) and non-woven jute fabrics (NWJF) were fabricated by sandwiching non-woven jute mat between PLA sheets. First, composites were fabricated with various weight proportions of jute fabric (5, 10, 20, and 30 wt.%) with the PLA matrix, and the effect of fabric loading on their mechanical properties was investigated. Higher mechanical properties were f...

In this work, several fabrics with different composition and structure have been used as the substrate for production of wearable textile-embroidered dipole antennas. The performance antennas has determined by measuring their resonance frequency, return loss bandwidth. To determine durability fabrics, assessed before after subjecting to washing abrasion cycles. results revealed that woven prese...

Invasive alien plants that damagingly overgrow native ecosystems can be beneficially used to produce natural dyes. Natural dyes are healthier and more environmentally friendly than synthetic dyes, so their use on textiles other products come into contact with humans is desirable. In this study, the possibility of using a dye extracted from purple petals invasive plant Impatiens glandulifera Roy...

Polymeric hybrid nanocomposites, due to improved mechanical, thermal, and electrical properties, are key factors in recent technologies. Because of anisotropic characteristics polymeric mechanical properties their behavior very difficult predict. If they fabricated with complicated woven fabric patterns, it becomes more This review discusses detail the manufacturing methods various fibers, focu...

Constructions of woven graph codes based on constituent convolutional codes are studied, and examples of woven convolutional graph codes are presented. Existence of codes satisfying the Costello lower bound on the free distance within a random ensemble of woven graph codes based on s-partite, s-uniform hypergraphs is shown, where s depends only on the code rate. Simulation results for Viterbi d...

Flexural strength and modulus of woven glass fiber-reinforced specimens werc significanLly greater than those without woven glass fiber (p<O.OD, Likewise, comprossive strength of reinforced specimens was signifieantly greater than those without woven glass fiber (p<O.Ol), except for specimens rcjnforced with woven glass fiber oriented at a tilt directio...

Previous morphometric analyses, carried out by means of the light microscope under ordinary and polarized light, show the existence of a close correlation between collagen texture and shape, size, and spatial orientation of the osteocytes (Marotti, 1979, 1981). In woven bone the osteocyte lacunae show an irregular globous shape, whereas when the collagen fibers follow a preferential orientation...
