The possibility of recycling glass fibre-reinforced composites by using microwave pyrolysis was examined. A scrap blade from a wind turbine fragmented and microwave-pyrolysed. fibre recovered after represented 70% the initial mass . tensile strength measured compared to untreated fibre. test showed that fibres lost about 25% their tenacity. Non-woven mats were prepared fibres. Laminates then non-woven obtained, together with virgin mats. Mechanical testing laminates it is possible prepare 25...

Biocomposites reinforced by natural plant fibers tend to be brittle, moisture sensitive and have limited strength. Wood cellulose nanofibers (CNF) were therefore used reinforce an unsaturated polyester matrix (UP) without the need of coupling agents or CNF surface modification. The nanostructured network reinforcement strongly improves modulus strength UP but also ductility toughness. A template-based prepreg processing approach industrial potential is adopted, which combines high content...

Abstract Fiber-based scaffolds produced by textile manufacturing technology offer versatile materials for tissue engineering applications since a wide range of crucial scaffold parameters, including porosity, pore size and interconnectivity, can be accurately controlled using 3D weaving. In this study, we developed weavable, bioactive biodegradable composite fiber from poly (lactic acid) (PLA) hydroxyapatite powder melt spinning. Subsequently, these fibers were fabricated The differentiation...

Bioplastics that possess characteristics like durability and low cost are desired for versatile applications in industries such as automotive manufacturing, marine transport aerospace applications, the building industry. The industry is an example of now shifting towards a more focused approach addressing issue concerning sustainability development sustainable material. To achieve lightweight construction, one methods used by original equipment manufacturers substituting conventional...

The aim of this study was to develop and additively manufacture polypropylene-hemp fiber (PPHF) composites, which were composed polypropylene (PP) hemp fibers (HF) in various percentages (5%, 10%, 20%). objective examine the mechanical properties water absorption behaviors extruded PP, conventional filament PP PPHF composites. findings flexural tensile tests provided important valuable information. In comparison other materials examined, had highest modulus strength, but lowest properties....

This study investigates the morphology and thermo-mechanical properties of cross-linked polyethylene (PEX) pipes for potential use in high-temperature borehole thermal energy storage systems. Particular attention is given to a novel type PEX pipe produced through photoinitiated cross-linking (PEX-e). Two formulations, PEX-e1 PEX-e2, were analyzed compared peroxide-cross-linked (PEX-a) non-cross-linked bimodal (PE100) pipes. The degree was evaluated via gel content, while cross-link density...

Composite fibers from poly(lactic acid) (PLA) and hydroxyapatite (HA) particles were prepared using melt spinning. Different loading concentrations of HA (i.e., 5, 10, 15, 20 wt %) in the PLA solid-state draw ratios (SSDRs) evaluated order to investigate their influence on fibers' morphology thermal mechanical properties. A scanning electron microscopy investigation indicated that homogeneously distributed fibers. It was also revealed by atomic force Fourier transform infrared spectroscopy...

World is facing numerous environmental challenges, one of them being the increasing pollution both in atmosphere and landfi lls.After goods have been used, they are either buried or burnt.Both ways disposal detrimental hazardous to environment.The term biodegradation becoming more important, as it converts materials into water, carbon dioxide biomass, which present no harm environment.Nowadays, a lot research performed on development biodegradable polymers, can "vanish" from Earth surface...

Poly(lactic acid)-cellulose nanocrystals (PLA/CNC) nanocomposite fibers with 1% weight fraction of were prepared <italic>via</italic> melt-spinning.

This systematic review concerns the use of smart textiles enabled applications based on myoelectric activity. Electromyography (EMG) is technique for recording and evaluating electric signals related to muscle activity (myoelectric). EMG a well-established that provides wealth information clinical diagnosis, monitoring, treatment. Introducing sensor systems allow ubiquitous monitoring health conditions using textile integrated solutions not only opens possibilities ambulatory, long-term,...

Abstract Biobased composites were manufactured with a compression‐molding technique. Novel thermoset resins from soybean oil used as matrix, and flax fibers reinforcements. The air‐laid stacked randomly, the woven fabrics crosswise (0/90°), impregnation was performed manually. fiber/resin ratio 60 : 40. prepared biobased characterized by impact flexural testing. Scanning electron microscopy of knife‐cut cross sections specimens also done to investigate fiber–matrix interface....

Abstract An oxidative chemical vapor deposition (OCVD) process was used to coat flexible textile fiber (viscose) with highly conductive polymer, poly (3,4‐ethylenedioxythiophene) (PEDOT) in presence of ferric (III) chloride (FeCl 3 ) oxidant. OCVD is a solvent free get uniform, thin, and polymer layer on different substrates. In this paper, PEDOT coated viscose fibers, prepared under specific conditions, exhibited high conductivity 14.2 S/cm. The effects polymerization such as time, oxidant...

A bio-based thermoset resin was reinforced with flax fabrics and Lyocell fiber. The effect of different weave architectures studied four architectures: plain, twill (two types), dobby. the outer ply thickness characterized flexural impact testing. Composites manufactured plain reinforcement had best mechanical properties. tensile strength, modulus, strength were 280MPa, 32GPa, 250MPa, 25GPa, 75 kJ/m 2 , respectively. Reinforcements twill-weave architecture did not impart appreciable or...
