Assessment of physical and mechanical properties of an engineered wood flooring made of different wood properties
Engineering wood flooring (EWF) has made a considerable progress in recent years due to the combination of different species of wood primarily with low density cores and high density veneers. The goal of this work was the development and characterization of an engineered wood flooring, three layers, 16 mm thickness. Two low density wood species of either coconut palmwood (Cocos nucifera) or melina wood (Gmelina arborea) and a hardwood veneer of red oak (Quercus castanea), glued with a green free formaldehyde adhesive, soybean based, were used to elaborate the new plank (EWF). The effect of different wood properties on the physical and mechanical properties of engineered wood product were measured. Either coconut palmwood or melina EWF had a density of 0.53 g/cm3 and moisture content 9%. Meanwhile, the flexural strength (MOR) ranged from 40 to 70 MPa, modulus of elasticity (MOE) around 10,700 MPa, and internal bond 2.7 MPa. With regard to the Brinell hardness, the EWF manufactured with coconut palmwood and red oak exhibited a higher value than EWF those made with melina and red oak (35 N/mm2 and 24 N/mm2 respectively). The EWF have good mechanical properties, its a light weight material and reached the requirements for EWF according ANSI/HPVA EF 2009 Standars.
