This paper presents a method for evaluating Young’s modulus of materials based on air-coupled ultrasonic technology. Firstly, the air-coupled ultrasonic transducer is developed based on 1-3 piezoelectric composites and double-layer matching structure. In the mode of one-transmitter-one-receiver, the insertion loss and -6 dB bandwidth of the designed air-coupled ultrasonic transducer are -23.9 dB and 26.9%, respectively. Then, an experimental platform is set up to evaluate the Young’s modulus of copper wire and silver wire by combining the static tensile method and air-coupled ultrasonic technology. The evaluated results are consistent with the corresponding recognized values.
