Abstract

Micro X-ray computed tomography (XCT) is an emerging technology that has found many applications in biology and the study of materials. Synchrotron-based micro computed tomography has been adopted for the study of adhesive bonding in wood. This paper reviews recent developments of an integrated project that uses micro XCT to assist with modeling of adhesive bonds and to assess the role of cell wall penetration on moisture resistance.  The research includes study of: anatomical features of several commercially important wood species, penetration of three adhesive types into wood, moisture effects on bonding, and mechanical performance of bonds during XCT scanning.
