Properties of hybrid particleboard from acacia (acacia mangium) and oil palm trunk (elaeis guineensis) / Wan Jamalludin Wan Omar

The purpose of this study is to evaluate the properties of the hybrid
particleboard made from Acacia and Oil Palm Trunk and to evaluate the
effects resin content and wood ratio on the particleboard properties. This study
measured using Acacia (100%) then Acacia + Oil Palm Trunk (50%:50%) and Oil Palm Trunk (100%)
this study used the middle part from both species and
the target density was fixed at 650kg/m3.Twenty seven board were produces
for test physical and mechanical properties every sample to achieve target
density 650 kg/m3. The resin content of board were 7%, 9% and 11% and
phenol Formaldehyde resin (PF) was the resin used. All properties tested
were the based on the European Standard (EN). On the mechanical
properties, from of the three wood ratio, 100% acacia show the highest value
for Modulus of Rupture (MOR) from 11% resin content with 15.2 MPa and the
lowest value from wood ratio 100% OPT, 7% resin content with 3.7 MPa.
meanwhile the best value for Modulus of Elasticity (MOE) is from wood ratio
100% acacia with 11% resin content and value of MOE is 2427 MPa. Then
for internal bond (IB) result show that the highest value from wood ratio 100%
Acacia from 11% resin content with value 0.49 MPa and the lowest value
wood ratio 100% OPT 7% and 9% resin content with value 0.05 MPa. On the
physical properties, the best value of Thicknes Swelling (TS) from wood ratio
100% OPT (11% resin content) with value 7.98% and the less value from
wood ratio 100% acacia (&5 resin content) with value 13.89%. Then, the best
value of Water Absorption (WA) from wood ratio 100% Acacia (9% resin content) with 62.24%
and the less value from wood ratio 100% OPT (7% resin
content) with 81.38%. All of the sample from mechanical properties achieved
the standard compared sample from physical properties
