Abstract The research explores mechanical behavior and dynamic responses of carbon fiber-reinforced polyethylene terephthalate glycol (CF-PETG) composites which were manufactured through Fused Filament Fabrication (FFF) additive manufacturing. ASTM-standard PETG specimens reinforced with 10% as well 20% 30% fibre underwent tensile strength testing modal analysis while FEA validated the results. A FlashForge FFF 3D printer produced printed samples variations raster angle positions (0°, 90°, ± 45°) along nozzle temperature levels ranging from 250 °C to 320 layer thickness ranges 0.1 mm 0.35 mm. CF-PETG had a 60 MPa 25% increase compared pure experiencing Young’s modulus rise 2.3 GPa 3.8 GPa. natural frequency measurement impulse hammer accelerometer revealed that clamped-free-end (CFE) clamped-closed-end (CCE) evaluation both displayed 18% higher readings for respectively. significant fiber-matrix affinity decreased pores confirmed FESEM microscopy results whereas computational models only exhibited slight deviations below experimental findings. preliminary study shows enhances properties also improves dynamical because its potential aerospace automotive market applications researchers should focus on thermal stability better fiber dispersion techniques in upcoming work.
