The thickness of the boards was reduced with compression ratios of 40%, 60% and 75%. Since densified wood tends to recover from compression, especially under humid conditions, this study examined the set-recovery and the hygroscopic behavior of THM densified oil palm wood. The equilibrium moisture content (EMC), differential swelling and swelling coefficient, linear swelling and shrinkage as well as the differential swelling anisotropy were determined under climate conditions with different relative humidity (RH) (20°C/35% RH, 20°C/65% RH and 20°C/85% RH). The maximum swelling was measured after water soaking and the remaining set-recovery was evaluated after re-drying at 103°C. The EMC was reduced by the THM process by around 20%. In the direction of compression (thickness), the densified specimens show higher values for all analyzed swelling and shrinkage parameters than the undensified specimens from the equivalent position within the trunk. The maximum swelling in thickness of 22–38% during water soaking is mostly reversed by shrinkage during re-drying and a comparably low remaining set-recovery of 3–8% is measured at oven dry condition."}],"year":"2024","author":[{"id":"74242","full_name":"Kölli, Nathan","first_name":"Nathan","last_name":"Kölli"},{"last_name":"Frühwald-König","first_name":"Katja","id":"26232","full_name":"Frühwald-König, Katja"},{"first_name":"Martin","full_name":"Hackel, Martin","id":"79798","last_name":"Hackel"}],"department":[{"_id":"DEP7018"},{"_id":"DEP1309"}]},{"user_id":"83781","type":"industry_journal_article","place":"Berlin","_id":"11823","doi":"https://doi.org/10.1007/s00107-024-02131-w","has_accepted_license":"1","publication_status":"published","isi":"1","publisher":"Springer","quality_controlled":"1","department":[{"_id":"DEP7018"}],"abstract":[{"text":"This study investigates the macromechanical and micromechanical behavior of oil palm wood by testing the elastomechanical properties in bending, compression parallel and perpendicular and tension parallel and perpendicular to the vascular bundles of small-size test specimen depending on the position within the trunk, the density and the number of vascular bundles per unit area as well as the plantation site. All properties tested show a much higher exponential increase with the density, following power law relationships with exponents > 1, than common wood species and a significant gradient over both trunk height and cross section. Oil palm wood can be seen as a unidirectional long-fiber-reinforced bio-composite, if vascular bundles are considered as reinforcements (fibers) and parenchymatous ground tissue as matrix. The adapted rule-of-mixture based on the number of vascular bundles per unit area can be confirmed for the density, but not for the tensile properties, because the number of vascular bundles per unit area and share of fibers within the bundles is greater in the periphery than in the trunk central tissue. Furthermore, cell wall thickening over time is more pronounced in the peripheral than in the central tissue and more at the bottom than near the top. Different from small test specimens from common wood species, the compression strength exceeds the tensile strength: fc,0 : fm : ft,0 is 1.4 : 2.2–1.2 : 1. The performance indices for minimum weight design by Ashby and coworkers are comparable to that for coconut and date palm wood.","lang":"eng"}],"date_updated":"2025-06-25T13:05:49Z","publication":"European journal of wood and wood products : Holz als Roh- und Werkstoff ","publication_identifier":{"eissn":["1436-736X"],"issn":["0018-3768"]},"date_created":"2024-08-17T06:41:58Z","keyword":["MECHANICAL-PROPERTIES","STEM","FAILURE"],"language":[{"iso":"eng"}],"oa":"1","citation":{"short":"K.

SPACH) and Noble fir (Abies procera REHD.) for Christmas trees, intending to convert them into high forests. Climate-related damage, especially since 2018, has significantly reduced spruce populations, requirering a shift towards climate-adaptable tree species in future forests. Additionally, to reduce CO2 emissions from construction, there's a push for expanding timber construction, requiring non-spruce species for load-bearing products and applications. Although Nordmann and Noble fir are potential alternatives to spruce, they are not yet integrated into European standardization for load-bearing construction. Therefore, an assessment of German-origin Nordmann and Noble fir for use in glued laminated building products (GLT and CLT) is underway. Kiln-dried lamellas are graded visually and by machine using longitudinal vibration, with selected lamellas tested for tensile strength. Various mechanical properties are determined using non-destructive and destructive methods to establish input parameters for Finite Element Analysis (FEA).

In this investigation, combined GLT from oil palm wood is tested in compression parallel and perpendicular and glulam lamellas in tension parallel to the vascular bundles. Strength and Young´s modulus in compression and tension parallel increase with the density by power law relationship. In contrast to dicotyledons, the strength in construction size exceeds that of small, defect-free test specimens (compression strength perpendicular), are in the same range (tensile and bending strength parallel) or only a little below (compression strength parallel). The specimen size does not influence the strength. The ratio of fc,0 : fm : ft,0 is 1.2 : 0.8 … 1.7 … 2.6 : 1 and fc,0 : fc,90 = 2.7 … 13.0 … 32.6 : 1 for ρ = 200 … 400 … 600 kg/m³; the ratio of Ec,0 : Em : Et,0 is 1.2 : 1.3 : 1 for ρ = 400 kg/m³. Ashby´s performance indices for minimum weight design rise with the density; the strength-density performance indices are comparable or only slightly lower than that for structural size softwood, whereas the modulus-density performance indices are much lower. The challenge in use of oil palm wood for load-bearing construction products is the low stiffness.","lang":"eng"}],"issue":"5","quality_controlled":"1","publisher":"Taylor & Francis","type":"scientific_journal_article","user_id":"83781","intvolume":" 19","place":"London","doi":"10.1080/17480272.2024.2303627","_id":"11113","title":"Compression properties of glued laminated timber and tensile properties of gluelam lamellas from oil palm wood","volume":19,"citation":{"ama":"Frühwald-König K, Heister L.

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"}],"conference":{"location":"Oslo, Norway","name":"13.

The applicability of ultrasonic testing (time of flight of three longitudinal, six shear and three quasi-shear wave measurements) for the characterization of all 12 elastic constants of oil palm wood hav-ing various densities was investigated under the assumption of an orthotropic material behavior. For the evaluation, the simplified uncorrected and the full stiffness inversion method were used.

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). Center boards from the top of the trunk had the highest dewatering rates while boards from the periphery at the bottom of the trunk (high density, low water content) showed the lowest.","lang":"eng"}],"publisher":"Springer Nature Singapore","type":"book_chapter","user_id":"83781","alternative_title":["ByPalma 2021, Kuala Lumpur, Malaysia"],"place":"Singapore","_id":"10593","doi":"https://doi.org/10.1007/978-981-19-6195-3_2","title":"Mechanical Dewatering of Wet Oil Palm Lumber Prior to Press-Drying","citation":{"van":"Frühwald-König K, Kölli N, Frühwald A.
