EFFECT OF TENON GEOMETRY, GRAIN ORIENTATION, AND SHOULDER ON BENDING MOMENT CAPACITY AND MOMENT ROTATION CHARACTERISTICS OF MORTISE AND TENON JOINTS
Likos, Erkan; Haviarova, Eva; Eckelman, Carl A.; Erdil, Yusuf Ziya; Ozcifci, Ayhan (Soc Wood Sci Technol, 2012)Bending moment capacity and moment rotation characteristics of mortise and tenon joints as a function of tenon geometry, grain orientation, length, and shoulder fit were examined. Bending moment capacity of all joints in ... -
Effects of heat treatment and surface roughness on bonding strength
Ozcan, Suleyman; Ozcifci, Ayhan; Hiziroglu, Salim; Toker, Hilmi (Elsevier Sci Ltd, 2012)The objective of this study was to determine the effect of heat treatment on bonding strength of the samples from four different species, namely Scotch pine, oriental beech, white oak and Uludag fir woods. The samples were ... -
EFFECTS OF SILICA GEL ON LEACHING RESISTANCE AND THERMAL PROPERTIES OF IMPREGNATED WOOD
Altun, Suat; Ozcifci, Ayhan; Senel, Ahmet; Baysal, Ergün; Toker, Hilmi (Slovak Forest Products Research Inst, 2010)The aim of this study was to increase the resistance of fire retardant chemicals for leaching in order to improve the fire resistance of wood. For this purpose, Scots pine (Pinus sylvestris L.) and Chestnut (Castanea sativa ... -

Ozcifci, Ayhan; Ayar, Serdar; Baysal, Ergün; Toker, Hilmi (Slovak Forest Products Research Inst, 2011)The aim of this study was to determine the effects of some impregnation parameters such as impregnation chemicals, impregnation durations, and impregnation methods on modulus of rupture (MOR) and modulus of elasticity (MOE) ... -
Fire properties of laminated veneer lumber treated with some fire retardants
Ozcifci, Ayhan; Toker, Hilmi; Baysal, Ergün (State Forest Products Research Inst, 2007)The objective of this study was to determine fire properties of laminated veneer lumber (LVL) prepared from beech (Fagus orientalis Lipsky) veneers treated with some fire retardants. Boric acid (BA), borax (BX), and di ... -
GLOSSINESS, COLOR STABILITY, AND SURFACE ROUGHNESS OF WOOD TREATED WITH SOME BLEACHING CHEMICALS
Ozcifci, Ayhan; Yapici, Fatih; Altun, Suat; Toker, Hilmi; Baysal, Ergün; Senel, Ahmet; Simsek, Hakan (State Forest Products Research Inst, 2009)The aim of this study was to determine the effects of different bleaching chemicals and their treatment time on glossiness, color stability, and surface roughness of wood. Spruce (Picea orientalis L.) and oak (Quercus ... -
Influence of weathering on adhesion strength of chemically treated and coated Scotch pine
Toker, Hilmi; Hiziroglu, Salim; Ozcifci, Ayhan (Elsevier Science Sa, 2012)The objective of this study was to evaluate the effect of weathering on adhesion strength of Scotch pine (Pinus sylvestris L.) samples treated with three concentrations of Tanalith-E. Treated samples were also coated with ... -
AN INVESTIGATION ON COMPRESSION PARALLEL TO GRAIN VALUES OF WOOD IMPREGNATED WITH SOME BORON COMPOUNDS
Toker, Hilmi; Baysal, Ergün; Ozcifci, Ayhan; Altinok, Mustafa; Sonmez, Abdullah; Yapici, Fatih; Senel, Ahmet (Slovak Forest Products Research Inst, 2008)This study was carried out to determine compression strength parallel to grain of wood impregnated with some boron compounds.
