Properties of particleboard produce from hybrid of Ludai and Kelempayan / Nur Mardiatul Fitriah Kamaruddin

This study is conducted to determine the mechanical and physical properties
of hybrid particleboard made from Ludai and Kelempayan hence evaluates
the effect of ratio and size of particle to board properties. Log of Ludai is
obtained directly from UiTM Jengka Forest Reserved. Particleboard is made
with target board density of 600 kg/m3 and particle ratio divided by 4 that are
100LD: 0KL, 70LD:30KL, 50LD:50KL, OLD: 100KL. Resin used is
Melamine Urea Formaldehyde (MUF). Particleboard with 2.0 mm particle
size has reach the minimum requirement for Malaysian Standard with
1617 MPa (LD100: KL0), 2301 MPa (LD70:KL30), 1710 MPa (LD 50:50)
and 1667 MPa (LD0: KL100). For MOR value, only particleboard with ratio
LD70: KL30 from 2.0 mm particle size were met the standard where the value
was 18.78 MPa. For IB, all particleboard successfully achieves the standard
require with the least value came from 1.0 mm particleboard from ratio of
LD70: KL30 with 0.38MPa. Result in thickness swelling shows only
particleboard from LD70: KL30 with particle size of 1.0 mm were met with
the minimum standard required which the value was 11.19%. Admixture of
Ludai in ratio and particle size causes decreasing performance to strength of
particleboard. The highest value is produced from board with ratio of
70LD: 30KL with particle size of 2.0 mm where has value of 2301 MPa for
MOE, 18.2 MPa for MOR, 1.80 MPa for IB, 18.77% for TS and 92.03% of
WA. Particleboard from hybrid of Ludai and Kelempayan has low potential
as a raw material for particleboard manufacturing because of the low
performance gave by Ludai species when it was mixed with Kelempayan.
