Apart from Young´s modulus parallel to the vascular bundles, the elastic properties of oil palm wood are not known. 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 lack of correlation between the density and the ultrasonic velocity when using flat transducers questions the applicability of this method for oil palm wood.}}, author = {{Frühwald-König, Katja and Faust, Benedikt}}, booktitle = {{Proceedings 22nd International Nondestructive Testing and Evaluation of Wood Symposium}}, location = {{Quebec City, Canada}}, pages = {{29--39}}, publisher = {{U.S. Department of Agriculture, Forest Service, Forest Products Laboratory}}, title = {{{Evaluation of Elastic Constants of Oil Palm Wood using Ultrasonic Measurement}}}, year = {{2022}}, } @misc{8926, author = {{Frühwald-König, Katja}}, location = {{Lichtenau/Westfalen}}, title = {{{Aktueller/künftiger Holzbedarf und Holzverwendung (stofflich und energetisch)}}}, year = {{2022}}, } @misc{8927, author = {{Wieland, Stefanie and Frühwald-König, Katja}}, location = {{Lichtenau/Westfalen}}, title = {{{Wald im Klimawandel - Neue Holzarten für das Bauen mit Holz}}}, year = {{2022}}, } @misc{10703, author = {{Frühwald-König, Katja}}, location = {{online}}, title = {{{Was kann Holz - außer klimafreundlich?}}}, year = {{2021}}, } @misc{10742, author = {{Stosch, Martin}}, pages = {{55}}, title = {{{Fügeverfahren und Mittel zur Durchführung des Verfahrens.

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. }}, author = {{Kölli, Nathan}}, booktitle = {{6th International Conference on Process Technologies for the Forest and Biobased Products Industries PTF BPI 2021 }}, editor = {{Young , Timothy M. and Petutschnigg, Alexander }}, keywords = {{Oil Palm Wood, Densification, Drying}}, location = {{St. Simons Island, Georgia / USA}}, title = {{{Densification and Press-Drying of Wet Oil Palm Lumber}}}, year = {{2021}}, } @inproceedings{6946, author = {{Frühwald-König, Katja}}, location = {{Düsseldorf}}, title = {{{Mit Holzprodukten nachhaltig in die Zukunft bei veränderten Holzsortimenten}}}, year = {{2021}}, }
