The idea supporting the investigation of current manuscript was to develop customized filters for air conditioners with different pore percentages and geometry additional advantage presenting antibacterial performance. This property expected due reinforcement Cu nanoparticles in polymeric matrix poly(lactic acid) (PLA) polyurethane (TPU). filaments were characterized by their chemical composition, thermal mechanical properties, behavior before after processing fused filament fabrication. An X-ray photoelectron spectroscopy showed that nanocomposite presented particles at surface valence states, including Cu0, Cu+, Cu2+. After processing, metallic are almost absent from surface, a result confirmed micro-computer tomography (μ-CT) characterization. Antibacterial tests made using solid-state diffusion mimic dry environment conditioner filters. bacteria proliferation hindered. However, no performance could be observed absence element on surface. Nevertheless, antimicrobial when evaluated liquid tests. Therefore, obtained results provide valuable indications developing new nanocomposites must maintain activity being processed tested conditions diffusion.

Novel Processes for the Production of Continuous Carbon Fiber-Reinforced Thermoplastic Polymers via Additive Manufacturing and Comparisons

Polymers, Journal Year: 2025, Volume and Issue: 17(5), P. 584 - 584

Published: Feb. 22, 2025

Continuous fiber-reinforced polymer (CoFRP) parts offer significant potential for reducing future product consumption and CO2 emissions due to their high tensile properties low density. Additive manufacturing enables the tool-free production of complex geometries with optimal material utilization, making it a promising approach creating load-path-optimized CoFRP parts. Recent advancements have integrated continuous fibers into laser sintering processes, allowing support-free improved properties. However, additive faces challenges such as long times, small component dimensions, defects like void content. New including Arburg Polymer Freeforming (APF), robotic direct extrusion (DES) integration thermoplastic tapes, sintering, enabled CoFRPs address these issues. A comparison new processes existing methods is necessary determine most suitable specific tasks. The fulfillment factor used compare composites different matrix fiber materials, representing percentage experimentally achieved relative theoretical maximum according Voigt model. varies significantly across materials. For FFF ranges from 20% 77% stiffness 14% 84% strength, an average 52% 37%, respectively. APF shows (94%) but lower strength (23%), attributed poor fiber–matrix bonding process-induced pores. DES process improves additional consolidation steps, achieving above-average values (67%). produced by novel LS also (85%) (39%), influenced suboptimal parameters defects.

A controlled laminate consolidation is one of the most essential approaches in production fiber-reinforced thermoplastics components. With use specific models, almost entire strength potential material can be exploited. However, a thermo-mechanical situ (TMIC) strategy fused filament fabricated (FFF) process continuous polymer composites (CFRPC) has not been considered so far and leads to deconsolidation defects 3D-printed material. These terms micro macro volumetric flaws joining zone indicate poor parameter selection inadequate consolidation. imperfections lead reduction fiber volume content significant deterioration mechanical properties. In this work, self-developed test rig presented, which able influence monitor during additive manufacturing (AM) with TMIC unit manner. To evaluate rig, construction implemented sensors were tested for full functionality. Subsequently, specimens characterization using three-point bending (3PB) tests microstructural analysis. Based on these results, TMIC, its dependent parameters (consolidation force, temperature, printing speed), presented. perspective future development AM CFRPC shown.
