Purpose The paper aims to present an investigation of wood bonding strength as a very important indicator for effective using in further manufacturing processes. Design/methodology/approach In this study, the wood bonding strength sensitivity was estimated based on grain orientation, feed speed, heating time and temperature, temperature and type of adhesive. Artificial intelligence methods were applied for this analysis because it is strongly a nonlinear process. Findings It was shown that the artificial intelligence tools could be useful, reliable and effective for the wood bonding strength sensitivity estimation. Afterwards the power consumption in in solid wood machining process is analyzed and estimated by the artificial intelligence tools. Originality/value Results shown that the wood bonding strength is the most sensitive for type of adhesive. Thus, the results of the present research can be successfully applied in the wood industry to reduce the time, energy and high experimental costs.

Wood Bonding

Majority of engineered wood product such as glulam, laminated veneer lumber and parallel strand lumber relies greatly on wood adhesive bonding and adhesive penetration. Determination of bonding strength and adhesive penetration of adhesive-wood could enhance effective utilization of wood as construction material. Kapur (Dryobalanops aromatica) and Kelat (Syzygium spp.) were two commercial Malaysian medium hardwoods were used in the study. Since pressure is essential during wood bonding, the purpose of the study is to determine the effect of different pressure on bonding strength and adhesive penetration. Kapur and Kelat samples were bonded using Phenol resorcinol formaldehyde (PRF) and press at three different pressures (100 psi, 200 psi and 300 psi). Shear stress of bond line and Adhesive penetration were measured. The result shows that Kapur has lower bonding strength compares to Kelat and both samples pressed with 200 psi pressure shows higher shear strength then 100 psi and 300 psi. The result of adhesive penetration shows that higher pressure applied during bonding assembly resulting in the higher adhesive penetration into the wood porous structure.

The aim of the study was to evaluate the applicability and performance of polyglycerol- and sucrose-based polyols as components of a simplified formulation of polyurethane adhesives. Colloidal silica was used as a viscosity control and reinforcing agent. The adhesives were examined in terms of reactivity, thermal stability, viscosity, work of adhesion, wetting, surface energy, and bonding strength on wooden substrates. Silica was found to increase gelling time, but markedly improved bonding strength and adhesion with substrates. Bonded solid beech wood samples prepared at 80, 110, and 130 °C showed shear strengths between 7.1 MPa and 9.9 MPa with 100% wood failure. The renewable resource-based polyols were demonstrated to be useful in formulation of polyurethane adhesives for furniture industry—especially with silica as a filler.
