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.","lang":"eng"}],"keyword":["Oil palm lumber","glue laminated timber","GLT","strength grading","elastomechanical properties"],"status":"public","department":[{"_id":"DEP7018"},{"_id":"DEP1309"}],"user_id":"26232","year":"2023"},{"title":"Technische Eigenschaften der Birke und Einsatz im Ingenieurholzbau","date_updated":"2023-10-25T12:58:17Z","date_created":"2023-09-14T18:34:04Z","language":[{"iso":"eng"}],"publication_status":"published","citation":{"chicago-de":"Frühwald-König, Katja. 2023.

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."}],"conference":{"name":"13th World Conference on Timber Engineering (WCTE 2023)","end_date":"2023-06-22","start_date":"2023-06-19","location":"Oslo (Norwegen)"},"user_id":"83781","year":"2023","corporate_editor":["Norges miljø- og biovitenskapelige universitet ","Norges teknisk-naturvitenskapelige universitet ","Arkitektur- og designhøgskolen i Oslo"],"department":[{"_id":"DEP7018"},{"_id":"DEP1309"}],"status":"public","publication":"Timber for a livable future : World Conference on Timber Engineering : WCTE 2023 : 19-22 June 2023, Oslo, Norway ","date_updated":"2024-06-03T14:10:01Z","doi":"10.52202/069179-0088","title":"FLEXURAL PROPERTIES OF OIL PALM WOOD BASED GLUE LAMINATED TIMBER USING FINITE ELEMENT METHOD","type":"conference_editor_article","author":[{"last_name":"Hackel","id":"79798","full_name":"Hackel, Martin","first_name":"Martin"}],"publication_identifier":{"isbn":["978-1-7138-7329-7"],"eisbn":["978-1-7138-7327-3"]},"citation":{"din1505-2-1":"Hackel, Martin ; Nyrud, A.

The moisture content varies, reversely to the density, with the highest values of up to 600% at the trunk core, especially at the top of the palm trunk. Kiln drying material with such low density, very high moisture content and high sugar and starch content is difficult and often produces drying defects such as cell collapse, cracks, and mold. Mechanical dewatering of wet oil palm lumber in an unheated double roller press reduces the water content and generates sugar-containing pressed water (sap) that could be used as a source for biochemicals. The share of mechanically removed water varied from 1 to >54% of the total water removed from wet to dry state (at 20 °C, 65% rh).

Wood prices are rising because of increasing market demand while simultaneously forests are challenged through conservation issues, deforestation and hazards. The main reasons for deforestation are agriculture, infrastructure and wood harvesting. Oil palm plantations stock on former tropical forest land and cover some 25 Mio ha worldwide. They are replanted every 25 years due to reduced productivity. Using the available wooden trunk material of the cleared plantation not only makes sense in ecological terms but is also a big chance for economy and trade. Research over the last 30 years has led to several ideas in the use for products. The biggest challenge is the anatomical structure of palm wood which is different to coniferous or broadleaf trees. Hard vascular bundles are embedded in low-density parenchyma storage tissue with high moisture content. The soft and sponge-like parenchyma tissue can be compressed easily and a significant share of the water (mc up to 600 % based on dry wood) can be squeezed out. Through press drying, the volume of the parenchyma can be reduced and the wood density increases. Wood strength and stiffness are related to its density and can be improved by densification. TH OWL developed a four-step densification process for oil palm boards. Oil palm lumber was produced from oil palm trunks in a sawmill and then densified under defined conditions. The densification process includes (1) compression to remove a certain percentage of the palm sap, (2) plastification under heat and moisture to soften the wood, (3) hot compression to achieve the densification and remove more water, and (4) press-drying to dry and harden the material. A future perspective on how the laboratory tests could be scaled up to an industrial application with a possible machinery set-up is presented.
