Abstract

The present study investigates the influence of degradation effects due to natural aging of a pine wood by using acoustic birefringence measurements. In the present study, the acoustic anisotropy parameter for aged and un-aged Mexican pine (Pinus strobus) wood was calculated by the ultrasonic emission-transmission technique. The experimental measurements were carried out using a shear wave ultrasonic transducer with a central frequency of 0.5MHz. Ultrasonic velocity data and scanning electron microscopy (SEM) were performed, establishing a direct correlation with the shear wave velocity and the acoustic anisotropy parameter developed on the naturally aged and un-aged wood.
