Transforming waste polypropylene (PP) and carbon fibre into upcycled composite materials for additive manufacturing represents an ideal circular economy challenge. An optimized method material extrusion 3D printing was developed to overcome adhesion warpage challenges during printing. The study explored the impact of varying weight fractions (0 wt%, 2 5 8 15 25 wt%), firstly on properties filament then printability mechanical printed specimens. Optimized parameters yielded successful fabrication fibre-reinforced filaments. Micro-level assessment polymer revealed a decrease in due thermal processes making Microstructural analysis, along with optical scanning electron microscopy, provided insights inter-bead voids, debonding, dispersion, fracture modes, filament/sample quality. Differential Scanning Calorimetry indicated slight matrix degradation extrusion, leading slightly reduced melting crystallization temperatures.

In recent years, the creative use of polymers has been expanded as range achievable material properties and options for manufacturing post-processing continually grows. The main goal this research was to design develop a fully-functioning extrusion additive device with capability produce functionally graded high-temperature thermoplastic PEEK (polyether ether ketone) materials through manipulation microstructure during manufacturing. Five different strategies control chamber temperature crystallinity were investigated, concepts thermal introduced govern crystallisation cooling mechanics process. interaction individually deposited beads printing process investigated using scanning electron microscopy observe quantify porosity levels interlayer bonding strength, which affect quality final part. Functional testing printed parts carried out identify crystallinity, boundary layer adhesion, mechanical behaviour. Furnace annealing found be most effective methods, resulting in highest Finally, cylindrical part successfully, incorporating both low high crystalline regions.

The low carbon footprint, biodegradability, interesting mechanical properties, and relatively price are considered some of the reasons for increased interest in polylactic acid-based (PLA-based) filaments supplied with natural fillers. However, it is essential to recognize that incorporating fillers into virgin PLA significantly impacts printability resulting blends. complex inter-relationship between process, structure, properties context fused deposition modeling (FDM)-manufactured biocomposites still not fully understood, which thus often results decreased reliability this technology biocomposites, accuracy, presence defects manufactured biocomposite samples. In light these considerations, study aims identify optimal processing parameters FDM manufacturing process involving wood-filled biocomposites. This presents an optimization approach consisting Grey Relational Analysis conjunction Taguchi orthogonal array. has identified combination a scanning speed 70 mm/s, layer height 0.1 mm, printing temperature 220 °C as most optimal, highly satisfactory good dimensional accuracy (Dx = 20.115 Dy 20.556 Dz 20.220 mm) voids (1.673%). experimentally determined Grade specimen optimized set (0.782) was agreement predicted value (0. 754), substantiating validity process. Additionally, research compared efficacy integrated multiparametric method conventional monoparametric strategy. method, combines array, exhibited superior performance. Although strategy yielded specimens favorable values targeted analysis remaining characteristics uncovered unsatisfactory results. highlights potential drawbacks relying on singular approach.

Benefitting from lightweight, high strength, long life, and green recyclability, continuous fiber reinforced thermoplastic composite (CFTPC) pipes have attracted extensive interest, especially in the on-orbit additive manufacturing of structural components. However, preparation CFTPC remains challenging due to limited space processing temperature resin. Here, we report an effective approach for performance carbon fiber/polyether-ether-ketone (CF/PEEK) thin-walled via bidirectional reinforcement using pultrusion-winding technique. The fabrication can be achieved, but limitation by size core mold is also broken. compressive shear CF/PEEK with different layer designs been studied based on experiments simulations. With increase axial prepreg tape layer, resultant exhibit greatly improved compression strength. finite element analysis indicates that maximum stress decreased enhancement. flexural strength proved cycles. simulation confirms circumferential strain effectively reduced. facile controllability this highlight their suitability utilization large-scale structures.

The usage of basalt fiber in the engineering industries has gained significant interest due to its characteristics such as alkali resistance and enhanced mechanical properties. Similarly, E-glass-fiber-reinforced composites have been widely used fabrication electrically resistive industrial components switches, circuit panels, covering cases.
