An asymptotic method of multiple scales has been used to model wave propagation normal to the layers of a tri-laminated composite where each of its major constituents is sandwiched between two bonding layers. The model has the form of mixture equations of three constituents and two common directors. The efficacy of the model is assessed by comparison of predicted and exact phase velocity spectra and stress profiles in the cell for time harmonic waves. It is also found that the influence of the bonding agent on the first mode phase velocity spectrum is insignificant. However, a significant variation of the stress in the bonding layers suggests the necessity of the proposed model which can recover a continuous stress-microstructure in the cell.
