  text: The wood from oil palm trunks exhibits significant variations in distribution
    of structural tissue, density and elastomechanical properties across and along
    the trunk. Its reliable, safe, and economic usage for load-bearing purposes, such
    as glued laminated timber (GLT), requires a precise definition of its elastomechanical
    properties through appropriate strength grading procedures. Oil palm lumber is
    strength graded according to its density using an X-ray technique in which 50
    % of the lamellas are ripped, graded, edge glued and therefore density homogenized,
    and 50 % are cut only according to their geometry. Lamellas are tested in tension
    parallel to the vascular bundles; combined GLT is produced from strength-graded
    lamellas and tested in bending parallel and compression parallel and perpendicular
    to the vascular bundles. The characteristic strength values for C10 and C14 according
    to EN 338 are achieved. A correlation between density and elastomechanical properties
    is estab-lished. GLT from density-homogenized lamellas achieve higher bending
    properties than from lamellas with a “natural” density gradient across the width.

  text: The anatomical structure of oil palm wood is only to a limited extent comparable
    to common wood species used in construction. Typical for monocotyledons, the material
    is composed of high density vascular bundles and a parenchymatous tissue of lower
    density. In three experiment sets, the local and global moduli of elasticity (MOE)
    and the flexural strength of oil palm wood based GLT are determined using FEM
    and various influencing parameters are investigated in a sensitivity analysis.
    Furthermore, the application of densified tension lamellas is studied. The results
    of the modelling are compared with the results from mechanical tests. Significant
    differences, mainly attributed to the specific parameters of the selected material,
    are observed. The results of this preliminary study serve as a starting point
    for computer-aided optimisation and modelling of other oil palm-based products.
