Characterization of continuous carbon fibre reinforced 3D printed polymer composites with varying fibre volume fractions

Fused deposition modelling (FDM) is one of the most popular additive manufacturing (AM) technique which used to investigate elastic properties 3D printed polyamide-based polymer composites structures. The aim this work study mechanical continuous carbon fibre reinforced polyamide composite samples using tensile and flexural testing by varying volume contents with applying pressure, temperature holding for 60 minutes in platen press. results showed that strength stiffness increased increase content (fraction). Hot pressed exhibited about 27 % modulus 11 because increasing fraction from 29 35%. Synergetic effect both short was also studied, it observed were higher than only composites. Effects voids on fibre-reinforced quantified. A microstructure carried out scanning electron microscope (SEM). Following SEM analysis tested specimens, there a strong correlation between microstructure. Fibre measured acid digestion method determine amount before after hot pressing (compaction). From Micro- Computed Tomography (µCT) confirmed reduced void return modulus.
