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.
