EXPLORING THE SYNERGISTIC EFFECTS ON MATERIAL PERFORMANCE AND APPLICATION OF 3D PRINTED PETG/CARBON

Abstract

This study investigates the synergistic effects of integrating carbon fibers into PETG (polyethylene terephthalate glycol-modified) for 30 printing applications, aiming to enhance material performance and broaden the range of potential applications. PETG is favored in 30 printing due to its ease of use, chemical resistance, and durability, yet it often falls short in mechanical strength for demanding applications. By reinforcing PETG with carbon fibers, this research seeks to significantly improve its tensile strength, flexural strength, and impact resistance. The methodology involves creating PETG/carbon _ fiber composite filaments through a melt extrusion process, ensuring a uniform distribution of fibers within the polymer matrix. Various composites with differing carbon fiber contents are prepared and subjected to comprehensive mechanical testing to evaluate enhancements in material properties. The composites are then utilized in 30 printing to fabricate test specimens and functional parts. Results show that carbon fiber reinforcement leads to substantial improvements in the mechanical properties ofPETG. Tensile and flexural tests reveal marked increases in strength and stiffness, while impact resistance is notably enhanced. The study also explores the effect of fiber orientation and dispersion on overall material performance, with microstructural analysis via scanning electron microscopy (SEM) providing insights into the quality of fibermatrix adhesion. Additionally, the research evaluates the practical implications of using PETG/carbon fiber composites in various applications, demonstrating their potential in fields requiring high-performance materials, such as aerospace, automotive, and engineering. This investigation underscores the advantages of PETG/carbon fiber composites in 3 0 printing, offering a pathway to more robust and versatile printed components.er
