Wood particle composite board from Acacia mangium bark was made
from bark and wood chip with different ratio between outer and inner
layers. In this study, the board made from different ratio of Acacia
manguim bark chips : wood chips : bark chips are 30 : 40 : 30 (V3) and
20 : 60 : 20% (V4) have significant differrents on physical and mechanical
properties compare to pure fibre bark board (V1) or pure wood fibre wood
(V2). V3 and V4 board have some mechanical properties equal to the
standard of partical board. The static bending strength of these boards are
very hight, reached 27.11 MPa, two times higher than standard
requirement. The tensile strength perpendicular to surface of all boards
gained from 0.302 MPa to 0.47 MPa. This result shows that Acacia
manguim bark chips has significant impact on physical and mechanical
properties of particle composite board.
