Properties of finger jointing effect by adhersive types on three different species / Mohd Khaidir Mohd Nor

The finger jointing short pieces of lumber has become an increasingly popular
method of reducing wood waste and utilizing shorts to realize maximum profit from
the steadily rising cost of raw materials. This study was conducted to evaluate the
mechanical properties of finger jointing effect by adhersive types on three different
species at three species (Acacia mangium, neolamarckia cadamba and leucaena
spp.), and to determine the effects of species and adhesive used on finger jointing
system. This two adhesive and the combination of same species were tested in
horizontal orientation for bending properties (modulus of elasticity and modulus of
rupture) conforming to the European standard (EN 408:2003). The result revealed
that the speciment from the three species and the type of adhesive (polyvinyl acetate
and Epoxy) was strong enough to be use as material in funiture making. Thus, it can
be concluded that finger joint from Acacia mangium, neolamarckia cadamba and
leucaena spp. Using by types of adhesive (polyvinyl acetate and Epoxy) can
successfully be produced as the main source of raw materials for finger
