Paper Title:
Effect of Ultrasound Waves on Resin-infiltrated Time of Wood Materials Using a Peak-Delay Measurement Method
  Abstract

A nondestructive evaluation (NDE) technique would be very beneficial to assess resininfiltrated absorption effect of wood when wood was resin-treated. In this work, a wood material was nondestructively characterized and a technique was developed to measure ultrasonic velocity in wood using automated data acquisition software. We have proposed a peak-delay measurement method based on the pulse overlap measurement method. Also through transmission mode was performed to compare ultrasonic velocity with the above peak-delay measurement method in an immersion tank. The variation of ultrasonic velocity was measured and found to be somewhat consistent with those in infiltrated area in the course of nature absorption. For mapping out the material property inhomogeneity, through-transmission scans were used based on both amplitude and time-of-flight of the ultrasonic pulse. A peak-delay measurement method well somewhat corresponded to ultrasonic velocities of the pulse overlap method and through-transmission mode and C-scan image signal based on peak-to-peak amplitude.
