Low- Velocity Impact Damage Observation and Compression After Impact Strength Evaluation of 3D Printed Continuous Carbon Fiber Reinforced Thermoplastic Laminates

Abstract

In this study, we introduced out-of-plane low-speed impact damage for continuous carbon fiber reinforced thermoplastics (Continuous CFRTP) pseudo-isotropic laminates formed by a fused deposition modeling (FDM) type 3D printer, In addition to quantitatively evaluating the impact properties, the appearance of damage in the specimen was observed in detail using X-ray CT and an optical microscope , and the post-impact compressive strength was evaluated In addition to damage to the laminated composite material , damage patterns peculiar to 3D printer moldings could be confirmed.
