Numerical Simulation for Enhancing Joint Strength of CFRP Single-Wrap Bonds Through Post-Processing

We conduct a numerical simulation on the joint strength of single-wrap bonded joints in carbon fiber reinforced plastics (CFRP). After bonding two pieces of CFRP, we attempt to improve the joint strength solely through post-processing, such as beveling. Fracture analysis is performed using the finite-element analysis software ABAQUS, assuming that only the adhesive layer fails. Through post-processing, we are able to achieve an increase in joint strength of up to approximately 1.5 times, according to the numerical results. This study provides valuable insights into improving joint strength.
