Mechanical properties of finger joint from acacia manglum spp by adhesive types and tree portion / Umar Khattab Jamal

This study wass carried out to determine the properties of finger jointed Acacia
mangium spp with variables of tree portion top, middle and bottom and also adhesive
types namely PVAc and Epoxy. The physical properties test is to determine the
density and moisture content of Acacia mangium spp that was conducted accordance
to TAPPI standard 1'258 OM·94 (1996). The mechanical properties test is to
determine the Modulus of Rupture (MOR) and Modulus of elasticity (MOE) of
finger jointed Acacia mangium spp. The test was conducted in accordance to the
standard testing method for finger joint, ie . European Standard (EN 408:2003 Timber
Structures, Structural Timber and Glued Laminated Timber, Determination of Some
Physical and Mechanical Properties). For MOR, the sample from top and middle
portions shows the highest reading 40.9587 MPa and 42.2683 MPa. The bottom
portion shows the lowest 37.664 MPa For MOE, both sample from top portion and
middle portion are also the highest 11683.4717 MPa and 11688.267 MPa and the
lowest is bottom portion 11565.1983 MPa. For adhesives, the sample bonded with
Epoxy gives the higher value for MOR and also MOE, 49.9629 MPa and 11932.97
MPa
