Abstract
The aim of this study was to determine
the shear strength and fire performance of beech
(Fagus orientalis) plywood supported (SP) by woven E -
glass fiber (WGF). After providing 1.5 mm thickness
beech veneers from a commercial company, they were
manufactured as five layers. WGFs were placed bottom
of the surface layers of plywood. Urea formaldehyde
resin which contains 64% solid content was used
approximately at a rate of 170 g/m². Adhesive mixture
was spread on single surfaces of veneers by using
roller brush. Shear strength tests were performed on
the bond line 1 (contained WGF) and bond line 2 (not
contained WGF) according to TS EN 314-1 as air dried
and immersed in water. Fire performance tests were
carried out according to ASTM E-69 by using fire tube
test. SP samples have increased in reach to maximum
temperature approximately three minutes. In bond line
1, shear strength values of control plywood (CP)
samples have showed 7% higher shear strength
properties than SP samples in air dried. In bond line 2,
shear strength values of SP samples which are
immersed in water have increased by 45%
