Abstract
In continuation of our study into estimate potential bonding performance of bonded wood products from tropical fast growing tree species, a study on the bondability of Shorea sp, Acacia mangium Willd and Acacia hybrid from Malaysia was done. Two-ply laminations were produced using PVAc, UF, API and PRF adhesives. In order to determine the bonding performance, the block-shear test was applied according to JAS for structural glued laminated timber under normal conditions and after accelerated-aging treatments. Results showed that high percent wood failure of low-density Shorea sp indicated that the bondability of this species was far better than that of medium-density A. mangium and A. hybrid. Among the adhesives used in each wood species indicates that in Shorea sp and A. mangium, laminates bonded with UF, API and PRF seemed to have better bonding performance than PVAc. In A. hybrid, laminates bonded with API and PRF seemed to have better bonding performance than PVAc and UF.
