THE IMPACT OF CARBON FIBER REINFORCEMENT ON THE DURABILITY AND FUNCTIONALITY OF PETG IN 3D PRINTED

Abstract

The integration of carbon fiber reinforcement into Polyethylene Terephthalate Glycol (PETG) for 3D printed medical devices holds significant potential for enhancing their durability and functionality. This study investigates the effects of carbon fiber reinforcement on the mechanical properties, biocompatibility, and overall performance of PETG in medical applications. The research involves the fabrication of composite materials through advanced 3D printing techniques, followed by a comprehensive evaluation of their mechanical properties, including tensile strength, impact resistance, and fatigue behavior. Biocompatibility assessments ensure that the reinforced PETG composites are safe for medical use, with particular focus on cytotoxicity and inflammatory responses. The study also explores the thermal properties and dimensional stability of the composites to understand their behavior under typical sterilization processes. Results indicate that carbon fiber reinforcement significantly enhances the tensile strength and impact resistance of PETG, making the material more suitable for high-stress medical applications. Additionally, the reinforced composites exhibit improved fatigue resistance, suggesting a longer lifespan for medical devices made from these materials. Thermal analysis demonstrates that the composites maintain stability during sterilization, ensuring their suitability for repeated medical use. Biocompatibility tests confirm that the carbon fiber-reinforced PETG is non-toxic and does not induce adverse biological reactions. The findings of this study highlight the potential of carbon fiber- reinforced PETG as a superior material for 3D printed medical devices, offering enhanced durability, functionality, and safety. This advancement could lead to more reliable and long- lasting medical devices, ultimately improving patient care and treatment outcomes.
