Detection of glue deficiency in laminated wood with pulse thermography

 Adhesion problems sometimes occur during the production of laminated wood products. To minimize such quality problems, there is a need for a nondestructive test that can provide continuous control of the process and the product. This study presents results from measurements performed to evaluate the potential of pulse thermography as a method to detect glue deficiency in laminated wood. Defect depth, defect size, and degree of glue deficiency have been varied. The surface layer was made of merbau (Intsia bijuga) and the substrate of Scots pine (Pinus silvestris). The results showed that pulse thermography is a promising tool for detecting glue deficiency underneath the thin laminated wood surface layers, mainly because of the short inspection time. Lack of glue with a minimum thermal defect size of 3 was detectable (thermal defect size is defined as the quotient of defect size and defect depth). The penetration depth was 1.0 mm and the highest contrast, 0.62°C, was achieved for one of the largest defects (24 mm) below the thinnest (0.5 mm) surface layer after 1 second. Starved glue joints showed about half the contrast compared to areas with total lack of glue.

Recent research and development work on wood composites in Japan

Summary This paper highlights a number of articles on research and development on wood composites. The coefficient of variation in the mechanical properties of wood components tends to decrease when the thickness of the wood elements decreases. This finding was utilized in the manufacture of hollow cylindrical columns of laminated veneer lumber (LVL) from Cryptomeria plantation thinnings. In the future, the marketing of wood composite boards will tend toward two types: thick boards with low density properties and thin boards with fiber orientation. For the production of thick boards, fundamental parameters and application of steam-injection pressing have been studied, and continuous steam-injection pressing has been developed. For thin board production, generation principles of aligning torque in high-voltage system and the application has been studied. A new oriented mat former with electrodes positioned only at the reverse side of a forming belt has been developed. Various synthetic resins of low-molecular weight have been applied to improve dimensional stability of laminated products, such as LVLs and particleboards. Acetylation and formalyzation of fibers and particles were investigated to provide stabilized panels. High pressure steam treatment during pressing of wood composites has been studied and the process has been found effective and promising.The authors wish to thank Mr. Dwight A.
