| Abstract Scope |
This study presents the production and characterization of prototypes made of polycarbonate, PETG, and ABS fabricated via additive manufacturing, aiming to investigate their potential as electromagnetic radiation absorbing materials (ERAM). Test specimens were printed with different infill percentages and color variations to evaluate the influence of internal geometry and pigmentation on electromagnetic performance. The results indicated that absorption in the X-band is directly related to infill density and the material’s internal configuration, which are critical factors for electromagnetic wave dissipation. Thermal (TGA), morphological (SEM), and electromagnetic absorption analyses were conducted to correlate the internal structure of the polymers with their absorption capacity. It is concluded that, even in the absence of conductive fillers, geometric design plays a key role in the functional performance of the composites, opening new possibilities for applications in stealth technologies and electromagnetic shielding. |
