  text: Oil palm wood is mainly low in density and since strength and stiffness correlate
    with density, this study aimed to enhance the properties of oil palm wood through
    thermo-hygro-mechanical (THM) densification. In contrast to other studies using
    small laboratory-sized specimens, this study examined the densification of oil
    palm boards in sawn timber dimensions of 2.0 m length. Modulus of elasticity (MOE)
    and modulus of rupture (MOR) in bending, shear strength and shear modulus parallel
    by two-plate shear test and Young’s modulus in the three main directions as well
    as shear modulus in the three planes by ultrasonic testing were determined at
    densified and undensified specimens. The bending properties were increased to
    considerably higher levels and a compression ratio of 60% showed higher MOE and
    MOR values than that of 40%; whereas for boards of the inner part of the trunk,
    a compression ratio of 60% showed better results than that of 75%. The shear properties
    were only slightly increased through densification. Densification can improve
    the properties of oil palm wood. However, the wide range of density and properties
    found in natural oil palm wood is also present in densified oil palm wood.
