Composite layered materials from soft hardwood species imitating oak structure

Abstract

The study substantiates the feasibility of producing composite finishing materials from soft hardwood species that imitate the texture of oak. A method is proposed for manufacturing decorative finishing strips from rotary-cut veneer by alternating layers of veneers of different species and colors, which ensures a vivid and expressive structure resembling oak. It was established that the wave-like structure is achieved through veneer elements shaped like pyramids, placed within the glued veneer package. The degree of veneer layer curvature (waviness) is determined by the size, quantity, and spacing of these additional elements. Research was conducted to examine the relationship between the density of decorative strips and the parameters of the bonding regime, aiming to enable the production of higher-density products. A regression equation was derived to adequately describe the dependence of decorative strip density on bonding conditions, including pressing duration, veneer package thickness, and press plate temperature. Statistical processing and graphical dependencies were developed using computer programs such as PlanExp B-D13, Excel, and SigmaPlot. The study confirmed the possibility of producing decorative strips with increased density. © The Authors, published by EDP Sciences.
