The gluing characteristics of many of
the indigenous timber species of Bangladesh
are not known. Adequate knowledge of
the gluing characteristics is essential for
optimum utilization of the timber resources
by the repsective industries like plywood
and laminated wood. It is established a
fact that gluability is a function of density
of wood, its structure, presence of extraneous
materials, etc. The study was undertaken
in finding out the gluability of Champa
veneer in the manufacture of plywood. Champa (Michelia champaca) a large
tree with a long straight cylindrical bole of
18 to 21 m in length and often of large
girth, is found in the Chittagong Hill
Tracts forests of Bangladesh. It is light,
(sp. gr. approx. 0.53), soft, straight grained,
even and medium textured. Its sapwood is
white, and the heartwood is light yellowish
brown to olive-brown, somewhat lustrous,
smooth working and takes good polish.
It weighs 497 to 546 kg/m3 at 12 percent
moisture content. The timber dries well
