“…These high values were achieved with a 0.97% binder ratio, 70 °C pressing temperature, 25-min pressing time, and 1-to 3-mm thick particles (Guru et al 2006). The bending and internal bonding strength of particleboards produced from hazelnut shells and three different binders with densities of 0.6 g/cm 3 and 0.7 g/cm 3 were within standard limits (Copur et al 2007). The resistance properties of particleboards are greatly affected by wood defects and the inclusion of bark (Nemli et al 2004).…”

Mechanical properties of wood composites made from multiple wood species (50% Crimean pine, 30% Eastern Black Sea oak, 15% quaking aspen, and 5% wood machining residues) were evaluated using various amount of glass wool (GW) and stone wool (SW) additives. A total of 70 experimental panels were produced with a target density of 640 kg/m 3 . The bending strength, modulus of elasticity, tensile strength parallel to the surface of boards, tensile strength perpendicular to the surface of boards (internal bond), and cutting (shear) strength parallel to the surface of boards were determined. After statistical analysis, the results indicated that the SW and GW additives decreased the bending strength and modulus of elasticity by 49% in almost all boards. The addition of SW resulted in a 6% reduction in the tensile strength parallel to the surface. Relative to SW, GW resulted in an additional 8% reduction in shear strength, a 3% reduction in the screw tensile strength perpendicular to the surface, and a 6% reduction in the tensile strength parallel to the surface. Thus, the SW and GW additives decreased all the selected mechanical properties of wood composites.

“…The values of thickness swelling ranged from 6.26% to 24.54%. Copur et al 26 and Mendes et al 22 reported similar values for thickness swelling for boards produced from hazelnut husk and cassava bagasse, respectively. The highest value of thickness swelling was obtained for particle boards produced using an adhesive-cassava stalk ratio of 2:1 while the lowest thickness swelling was obtained for particle boards produced using an adhesive-cassava stalk ratio of 3:1.…”

We investigated the potential use of cassava stalks for the production of bonded particle boards. Particle boards were produced from cassava stalks using urea-formaldehyde as a binder. Water absorption and thickness swelling tests were carried out to determine dimensional stability of the boards while modulus of rupture and modulus of elasticity tests were carried out to assess the mechanical strength of the boards. Particle boards produced using an adhesive–cassava stalk ratio of 3:1 gave the best results in terms of the lowest mean values of water absorption (20%) and thickness swelling (6.26%), as well as the highest values of modulus of rupture (4×106 N/m2) and modulus of elasticity (2366.74×106 N/m2). The particle boards produced met the ANSI/A208.1-1999 standard for general-purpose boards. The results of analyses of variance carried out revealed that the adhesive–cassava stalk ratio had a marked influence (p<0.05) on the physical properties (water absorption and thickness swelling) but not on the mechanical properties (modulus of rupture and modulus of elasticity).

“…Use of agro-waste materials as a reinforcement in the production of WPCs alleviate the shortage of wood resources, and can have the potential to start a natural fiber industry in countries where there are little or no wood resources 5 . Çöpür et al 6 also believe that agricultural byproducts are excellent alternative waste materials to substitute wood because they are plentiful, widespread, and easily available. Apart from their abundance and renewability, utilization of agricultural wastes can be advantageous to economy, environment, and technology.…”

“…The main concern of obtaining reinforcements by incorporating wood fibers lies in the inherent incompatibility between the hydrophilic fibers and hydrophobic polymers, which results in a poor adhesion 6,7 . Thus, some coupling agents have been used in the modification of fibers, to increase the interfacial adhesion between cellulosic reinforcement and polymeric matrix and thereby improve the mechanical properties of the polymeric composite 8 .…”

This study investigates the feasibility of using recycled high density polyethylene (HDPE) and wood fiber from species Eucalyptus grandis (EU) to manufacture experimental composite panels. The use of maleated polyethylene as coupling agent (CA) improved the compatibility between the fiber and plastic matrix. The mechanical properties of the resultant composites were compared with polymer with and without compatibilizer. The influence of the coupling agent (CA) in the polymer matrices and composites were evaluated at different concentrations, checking the physical, mechanical and thermal properties of wood plastic composites (WPC). Results of mechanical, physical and thermal properties showed that concentration of 3% w/w CA in the polymer matrices was that which showed the best results, but in the composites properties were very similar in all formulations. Based on the findings in this work, it appears that recycled materials can be used to manufacture value-added panels without having any significant adverse influence on material properties.
