Some Mechanical Properties of Nylon Composite Plywood Produced from Different Wood Species
Öz
Abstract
Aim of study: Investigation of some mechanical properties of panels produced using polyethylene waste as adhesive instead of formaldehyde-based resins used in plywood was aimed and polyethylene amount was tried to determine for plywood produced from different wood species.
Area of study: This study was conducted at the Pilot Facility of Department of Forest Industry Engineering, Karadeniz Technical University in Trabzon, Turkey.
Material and Methods: Beech (Fagus Orientalis Lipsky), alder (Alnus glutinosa subsp. barbata) and Scots pine (Pinus sylvestris L.) veneers were used to produce polyethylene plywood. Three different polyethylene amounts was used (160, 200 and 240 gr/m2). Density, shear strength, bending strength and modulus of elasticity of plywood panels were determined according to TS EN 323-1, TS EN 314-1 and TS EN 310, respectively.
Main results: The best mechanical strength values for beech and alder were obtained from panels produced using 200 gr/m2 polyethylene amounts. Moreover, these values for Scots pine were found in panels produced using 160 gr/m2 polyethylene amounts.
Research highlights: When this study applies in the plywood industry, can provide to both recycle polyethylene waste and prevent formaldehyde release. Polyethylene plywood waste can be used production of wood plastic composite panels.
