A novel carbon-flax bioepoxy hybrid composite bone plate with enhanced bio-mechanical performance Eine neuartige Kohlenstoff-Flachs-Bioepoxid-Hybrid-Verbundwerkstoffknochenplatte mit verbessertem biomechanischen Verhalten

This study aimed to pioneer a transformative approach in orthopedic implant design by developing and analyzing a groundbreaking carbon-flax reinforced bioepoxy hybrid composite bone plate. The primary objectives of the present research were to enhance the bio-mechanical performance of orthopedic implants and explore the potential applications of the novel material for orthopedic implants. Hybrid composite plate was fabricated mimicking the human bone with the soft inner core and a rigid outer coating. Mechanical properties for the hybrid composite were obtained through material characterization studies as per ASTM standards. The hybrid composite bone plates were tested as per bio-mechanical test standard and the results were correlated with the finite element simulations. The maximum stress value in the experiments for the biomechanical four-point bending tests was 331.74 MPa, and the corresponding strain value was 0.0337. The maximum equivalent stress and strain values obtained from simulation were in line with the findings of the experiments. The current research signifies a paradigm shift in orthopedic implant technology. The carbon-flax bioepoxy hybrid composite offers remarkable potential for orthopedic applications, promising safer and more durable solutions for patients in need of bone repair or replacement.
