Effect of Densification Temperature and Some Surfacing Techniques on the Surface Roughness of Densified Scots Pine (Pinus sylvestris L.)
Imirzi, Hasan Ozgur; Ulker, Onur; Burdurlu, Erol (North Carolina State Univ Dept Wood & Paper Sci, 2014)The effects of densification temperature, planing, circular sawing, and sanding on the surface roughness of densified Scots pine using the open-system thermodynamic method were studied. Densification was applied to Scots ... -
The Effect of Densification Temperature on Some Physical and Mechanical Properties of Scots Pine (Pinus sylvestris L.)
Ulker, Onur; Imirzi, Ozgur; Burdurlu, Erol (North Carolina State Univ Dept Wood & Paper Sci, 2012)As wood's density increases, strength properties tend to increase due to a decrease in cavity volume. This study aimed to determine the effect of temperature levels in the densification process with an open-system ... -
Effect of Glass Wool and Stone Wool Additives on Some Mechanical Properties of Wood Composites
Ulker, Onur; Burdurlu, Erol (North Carolina State Univ Dept Wood & Paper Sci, 2016)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 ... -
Effects of Some Mineral Wools and Adhesives on Burning Characteristics of Particleboard
Ulker, Onur; Burdurlu, Erol (North Carolina State Univ Dept Wood & Paper Sci, 2015)In this study, effects of adhesive and additive's type and ratio on burning characteristics of particleboard (PB) added glass wool (GW) and rock wool (RW) were researched. PB's furnish was derived from 50% Crimean pine, ... -
Evaluation Of Corner Joint Strength Of Composite Panels Bonded With Modified Starch
Ulker, Onur; Derafs, Mercan Haddad (SLOVAK FOREST PRODUCTS RESEARCH INST, 2020)The objective of this research was to evaluate the strength of corner joints of box shaped furniture made from eastern red cedar (Juniperus virginiana L.) and corn starch binder southern sample.
