Abstract

In this work, we employed a wave mixing technique with an incident longitudinal wave and a shear wave to measure the Acoustic Nonlinearity Parameter (ANLP) of adhesive bonds. An adhesive transfer tape (F-9473PC) was used as an adhesive material: two aluminum plates are bonded together by the tape. To achieve a high signal to noise ratio, the optimal interaction angle and frequency ratio between the two incident waves were carefully selected so resonance occurs primarily in the adhesive layer, which somewhat suppressed the resonance in the aluminum plates. One of the most significant features of this method is that the measurements need only one-side access to the sample being measured. To demonstrate the effectiveness of the proposed technique, the adhesively bonded aluminum sample was placed in a temperature-controlled chamber for thermal aging. The ANLP of the thermally aged sample was compared with that of a freshly made adhesive sample. The results show that the ANLP increases with aging time and temperature.
