Abstract The current research has produced engineering plastics composite for automotive applications using waste recycled plastic polyethylene terephthalate (RPET) bottles as the matrix and compounded with chemically modified natural kenaf fibers in comparison virgin (PET) composites under same processing conditions. Kenaf were surface by alkali epoxy coating treatment methods. RPET which mechanically pulverized a 5 mm mesh size aperture into flakes melt‐mixed 10 wt% of short twin‐screw extruder compression‐molded at 240°С optimized temperature. Mechanical thermal analyses performed on both RPET, PET (VPET), their constituent composites. Scanning electron microscopy (SEM) was carried out to assess composite's morphological characteristics. results show that treated (TKF/RPET TKF/VPET) gave higher mechanical properties compared untreated (KF/RPET KF/VPET) its impact than VPET However, tensile flexural strength showed melting peak temperatures 252.9°C 245.8°C respectively. Both TKF/RPET TKF/VPET more thermally stable decomposed SEM strong fiber/matrix adhesion no clear evidence fiber degradation It can be concluded possessed similar counterpart serve substitute formulation.

To implement a circular economic life for thermoplastic waste, such as polylactic acid (PLA) waste from filament-based material extrusion (FME) printing and reduce the costs associated with producing filaments FME process, granule-based (GME) printer was developed by modifying head head. However, concerns have been raised about mechanical performance of parts printed using GME method. Previous studies reported mixed results, some finding inferior compared to counterparts, while others comparable or slightly better performance. Moreover, these were limited tensile flexural evaluations, lacked clear explanation support them. Therefore, address this uncertainty research gaps, comprehensive comparison analysis study conducted among specimens two types printers. Characterization tests conducted, including tests, impact 3-point bending hardness reveal properties parts. Furthermore, scanning electron microscope (SEM) differential calorimetry (DSC) thermal imaging, rheological gel permeation chromatography (GPC) carried out analyze explain results. The results indicated no significant differences (P > 0.05) in terms properties, strength modulus, strength. there difference shore D strain at break between methods, complex viscosity samples greater than that counterparts. Remarkably, average molecular weights higher those ones, which can be attributed lower actual temperature chamber due its different location heater, thermistor melting

Three-dimensional printing with waste acrylonitrile butadiene styrene: Processing and characterization

Journal of Reinforced Plastics and Composites, Год журнала: 2024, Номер unknown

Опубликована: Янв. 2, 2024

Three-dimensional (3D) printing of waste plastic such as acrylonitrile butadiene styrene (ABS) is challenging because multiple heating cycles and irregular cooling cause accumulation stress in 3D-printed structures, which significantly affects mesostructured fiber-to-fiber bond strength. Hence, this study demonstrates the ability to print high-quality parts via 3D using ABS waste. The different weight proportions (100, 90/10, 80/20, 70/30, 60/40, 50/50) recycled (RABS)/virgin (VABS) are selected for experimentation. It found that increasing VABS content RABS improved physical properties samples. Due blending RABS, average enhancement flexural strength (Sf), flex modulus (Ef), work fracture (WOF) 11.49%, 5.45%, 17.31%, respectively, when compared with 100% Similarly, increase Young’s (E), tensile at yield (Ty), ultimate (UTS) 7.71%, 5.19%, 3.51%, respectively. samples printed 50% RABS/50% blends show superior mechanical than others, also 90% RABS/10% 80% RABS/20% very close provides unique opportunities sustainable use technology.

Abstract Polyvinylidene fluoride (PVDF) is a smart piezoelectric material with remarkable properties, offering vast potential for applications in areas such as energy harvesting, biomedical devices, and sensors. Among its various crystalline phases, the β -phase most electroactive, characterized by high dielectric properties. Recently, PVDF has been processed using 3D printing due to technology’s ability fabricate complex intricate structures, along advantages design flexibility, efficiency, rapid prototyping. While content often enhanced through additives or post-processing, limited attention given role of feedstock preparation extrusion parameters phase enhancement. In this study, we investigated how influence PVDF, aiming optimize properties applications. filaments were produced two different methods: direct from pellets solution-based process involving dissolution solvent, followed extrusion. Phase content, structural changes, thermal stability assessed x-ray diffraction (XRD), Fourier-transform infrared spectroscopy, differential scanning calorimetry. Results show that processing conditions significantly impact crystallinity concentration filaments. Notably, solution-processed exhibited higher compared pellet-based method, suggesting approach may enhance performance. This study highlights importance techniques means tailoring electroactive advanced 3D-printed
