Enhanced mechanical properties of the hybrid CFRP-SLA laminates through laminate modifications

Enhanced mechanical properties on the hybrid laminates consist of carbon fiber reinforced polymers-stereolithography (CFRP-SLA) reported in the present study. Hybrid laminates can significantly increase tensile strength more than 4,2 times higher (91.35 MPa), and flexural strength 10.7 times higher (156.81 MPa) compared to bare 3D printed samples. The improvement can be achieved due to the modification of the surface of the 3D printed model which has empty cavities filled with resin to form an interlocking mechanism and improved adhesion between laminates. The model can delay catastrophic failure mechanisms. The study could potentially be applied in structural and aerospace fields. © 2024 Elsevier B.V.
