Wood composite panels used in trays would be destructive during its sampling process, which causes the waste of resources and time. The work aims to alleviate this situation and promote nondestructive testing. Longitudinal wave resonance method was used to test the resonant frequency and calculate the dynamic MOE of 9-layer plywood, LVL and a new type of LVL board. The correlation among dynamic MOE, static MOE and MOR was analyzed. The results showed that the dynamic MOE, static MOE and MOR respectively had strong linear correlation at the 0.001 level of plywood and LVL while they had certain linear correlation at the 0.001 level of new-LVL, slightly inferior to plywood and LVL. In conclusion, MOE and MOR of three wood composite panels have certain linear correlation. Applicability of longitudinal wave resonance method in new-LVL is slightly poorer than that in plywood and LVL.
