Wave impact pressure is one of the important physical quantities in ocean engineering. The traditional method of measuring wave impact pressure using pressure sensors has single measurement results and poor stability. Therefore, it is necessary to find a new measuring element to replace pressure sensors. In this paper, a macro fiber composite material (MFC) is used to measure the wave impact pressure of the model for a wave impact on a vertical plate. In order to verify the feasibility and accuracy of this measurement method, the measured values of wave impact pressure measured by MFC were compared with the calculated values of empirical formulas commonly used in ocean engineering. The experimental results show that the measurement results of MFC are in good agreement with the calculation results of our country's specifications; compared with our country's specifications, among all the effective data generated by the five incident wave heights, only the average error of the incident wave height of 5 cm exceeds 10 %, which is 18.25 %. The average error of the incident wave height of 12 cm is the smallest, with the smallest being 2.56 %.
