“…In order to establish the linear elasticity modulus for these [13] in his studies carried out on oar-shaped samples subjected to stretching. Stiffness of the urea-formaldehyde glue was investigated by Clada [22] who reported that the value of its Young's modulus ranged from 4940 to 5200 MPa. Therefore, the following values of the glue linear elasticity modulus were chosen (in MPa): 33 450, 4940, 465, 100, 50, 10, 0.…”

New technologies for wood building construction continue to employ various profileadhesive joints, with mortise and tenon joints being the most popular. Their strength depends both on the wood species and type of the applied glue, as well as the execution accuracy of individual elements. The aim of the performed experiments was to determine the size of normal stresses in places of mutual pressures of the tenon and mortise and the impact of the change of wood species and the type of glue (or lack of glue) applied to the joint on the value of those stresses. It was established, on the basis of numerical calculations, that the phenomena of the tenon and mortise contact are caused both by the bending of the tenon as well as by the torsion of the glue bond. Stresses in the direction perpendicular to the fibre course generating pressures exceeding wood compression strength turned out to be the most dangerous for the tenon and mortise joint. The value of the linear elasticity modulus of the glue bond exerts a decisive influence on the stress values caused by the mutual pressures of the elements of the examined joint.

“…According to Wilczyński (1988), the linear elasticity module Smardzewski (1998a), in conducting tests on samples in the shape of a paddle, subjected to tension. Clada (1965) dealt with determining the stiffness of ureaformaldehyde glue, according to whom the value of Young's modulus varies from 4940 to 5200 MPa. Based on this, the following values of the linear elasticity module of glue were selected in MPa: 33,450,4940,465,100,50, 10 and 0.…”

“…*Sorumlu Yazar (Corresponding Author) e-posta : altinok@gazi.edu.tr Clad (1964) and Brockmann et al (2005) found that for every 1% change of wood moisture, shear strength changes by 0,12 N/mm2, but also softening of the glue layer contributes to poor adhesion performance [8,9]. It has been reported that the adhesion performance of wood increases up to 80% when it is dried [6] .…”

In this study, the adhesion performance of oak (Quercus petrea Liebl.) And Scotch pine (Pinus Silvestris L.) wood samples that were heat treated and glued with 1K-PUR adhesive were kept under different conditions (A1-A4-A5) and moisture contents (20°C /% 35, 20°C /%65 ve 20°C /% 95), and then the adhesion performance was investigated.Rough sized pieces of both types of wood were heat treated at 195°C for 2 hours. Test samples were prepared from untreated and heat treated blanks (DIN EN 204). Tensile tests according to DIN EN 204 were applied to samples kept at 20°C/35%, 20°C/65% and 20°C/95% temperature and relative humidity, respectively, and the adhesion performance was determined in three climatic conditions.At the end of these tests, it was found that the holding environment and climatic conditions have a significant effect on the adhesion resistance. It was observed that the samples that were kept under A1 conditions and tested had wood rupture (error) between 70% and 100%, and the samples tested after holding in A4 and A5 conditions mostly broke off from the glue joint.
