Abstract

The aim of this study was to investigate the cutting direction in some wood types used in wood products industry on the bonding strength of wood-to-wood joint. The samples with different cutting directions prepared from the woods of Oriental beech (Fagus orientalis Lipsky), European oak (Quercus petraea (Mattu.) Liebl.), Scotch pine (Pinus sylvestris Lipsky) and Toros cedar (Cedrus libani A. Rich) have been glued with the Klebit-303 (K-303) and Kleiberit-305 (K-305) in diagonally tangential-radial (Di-TR), diagonally tangential-tangential (Di-TT), plain grain-grain (P-GG) joints of I-Type examples (by axial tension test) and diagonal miter joint (Di-MJ), diagonally tangential-grain (Di-TG), diagonal radial-grain (Di-RG) joints of L-Type examples (by diagonal tensile test) have been performed according to ISO 6237 standard. The results showed that the highest bonding strength was found to be 16.60 N/mm(2) in Oriental beech with the K-303 in Di-TR and the lowest to be 2.227 N/mm(2) in Toros cedar with the K-305 in P-GG by axial tension test, and the highest value was 10.98 N/mm(2) in Oriental beech with the K-303 in P-RG the lowest value was 3.197 N/mm(2) in Scotch pine with the K-305 in Di-MJ by diagonal tensile test. Thus, applying the Di-TR and Di-RG cutting order with the glue K-303 for bonding massive Wood pieces without using auxiliary bonding elements (tenon, rabbet, dowel, dovetail etc.) may offer advantages over others.
