Near Surface Mounted method, the attachment performance and bending performance were to be improved by using carbon plates to attach surface penetration to wood. To evaluate the bending performance, a new-sand beam was used to produce a complete CFRP plate surface injection experiment. All experiments were finally destroyed by bending failure by tensile side splitting, and experiments with three CFRP plates were measured 19.94% higher than those with no reinforcement, indicating in this experiment that bending reinforcement performance is improved by increasing the amount of adhesion of CFRP plates. Exterior Bonded Method, the attachment performance of CFRP plates to wood was improved using high-intensity bolts, and to evaluate the flexural reinforcement performance, the experiments and non-reinforced experiments were conducted by manufacturing CFRP plates that were reinforced with red-pine beams. As a result of the experiment, all of the subjects were finally destroyed due to bending failure caused by tensile side split of wood, and the average maximum strength of the subjects reinforcing the CFRP plate with high-power bolts was about 63.0% greater than that of the non-reinforced experiments. As a result, the bending reinforcement of wood by EBM reinforcement was evaluated to be better than NSM reinforcement in improving the flexural strength, which is thought to be due to the anchorage of the high-power bolt end the effect of the 2nd area moment.
