Abstract
The increasing demand on rubberwood by various industries in Malaysia is due to shortage in supply. Trend of replanting RW acerage vs oil palm trees have significantly reduced the future supply further. Subsequently the oil palm industries has been shown to be capable to generate large amount ofcellulosic residues in form of frond trunk and empty fruit bunches. These oil palm fibres are therefore potential substitution material for rubberwood in MDF manufacture. However there is no information as to whether these fibres could be mixed with the rubberwood fibres. This study looks at MDF board properties of admixtures of RW and EFB with ratio of 100RW 70RW30EFB 50RW50EFB 30RW70EFB and 100EFB. Analysis of variance were conducted to determine variance in Densities Moisture content MC Modulus of rupture MOR Modulus of elasticity MOE Internal bonding lB and thickness swelling for these admixtures. In bending strength all the boards passed the minimum requirement of the JIS A 5905:2003 for Type 30 board except for the board containing 100EFB which only achieve Type 15 board. The physical strength of properties MOR MOE and lB of the MDF board from 100RW fibre was significantly superior p0.05. The dimensional stability properties TS made from board admixture 70RW and 30EFB board were shown to be the best.
