“…It was reported in previous studies that the wooden material whose density was high also had a high bonding strength (Söğütlü et al 2016;Burdurlu et al 2006;Kılıç 2016).…”

“…The wood surface roughness values obtained using standards developed for homogenous materials have been related to several other properties, such as glueability, varnish adhesion, and weathering characteristics (Stumbo 1963;Peters et al 1970;Richter et al 1995;Taylor et al 1999;Söğütlü et al 2016). Based on the findings of Hiziroğlu et al (2013), it can be concluded that fine stylus-type equipment can be used to quantify the surface quality of specimens from wood species used as a function of sanding with different grit sizes of sandpapers.…”

The purpose of this study was to determine the effect of surface roughness on bonding strength in Oriental beech, cherry, Scots pine, and Taurus cedar woods. In conformance with this objective, after planing the wooden materials under different conditions, their surface roughness values were determined in accordance with various standards using scanning equipment. The bonding strength test specimens were prepared using polyvinyl acetate (PVAc) and polyurethane (PUR) adhesives after the wooden materials were separated into three groups of varying surface roughness values, after which bonding strength experiments were carried out. The data obtained from the experiments were evaluated statistically at a 95% level of confidence. According to the test results, the highest bonding strength was obtained in the Oriental beech (9.27 N/mm 2 ), whereas the lowest bonding strength was obtained in the Scots pine (3.65 N/mm 2 ). There was not a statistically significant difference between the bonding strength of the cherry and Oriental beech woods. The PVAc adhesive (7.61 N/mm 2 ) produced more successful results than the PUR adhesive (5.63 N/mm 2 ). Furthermore, it was found that in the specimens with low surface roughness values for each wood type and used adhesives had high bonding strengths.

Combined Surface Treatment of Polyethylene Wood-plastic Composites to Achieve Rapid Bonding with Desired Adhesion Properties

et al. 2017

View full text Add to dashboard Cite

To achieve rapid bonding with desired adhesion properties, a combined treatment of sanding then coating with polyisocyanate, followed by plasma discharge was implemented on the surfaces of polyethylene wood-plastic composites (WPCs). The surface properties of polyethylene WPCs were studied by evaluating the contact angle and bonding strength, as well as analyzing it via Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). The results indicated that the shear strength and durability of the bonding joints of polyethylene WPCs increased considerably due to the synergetic effect from the surface treatment. Thus, a rapid bonding with desired adhesion properties of polyethylene WPCs was achieved. The roughness and the oxygen content on the composites' surface increased after the combined treatment. Polar functional groups, such as -OH, -C=O, and -O-C=O, formed on the surface. At the same time, the presence of -NCO and -NH functionalities, generated during the combined treatment, showed that chemical bondings between polyisocyanate and the wood fibers of the composites occurred. The changes on the surface properties, such as roughness, wettability, as well as formation of chemical groups, substantially affected the adhesion properties of the bonding joint for polyethylene WPCs.
