Abstract The invention provides a nondestructive test method for quantifying defects of a composite laminated plate. The nondestructive test method comprises the following steps: (a) placing two sensors on the surface of the laminated plate and symmetrically distributing the two sensors in relation to defects at fixed spacing; (b) adopting a mode of one for sending and one for receiving, and acquiring a guided wave detection signal by a receiving sensor; and (c) processing the detection signal, obtaining characteristic parameters and performing quantitative evaluation on the defects. The nondestructive test method can help efficiently and more accurately quantifying the defects of the composite laminated plate.
