Special Issue Information

Dear Colleagues,

Wood modification is relied upon to enhance the physical, mechanical, and aesthetic properties of wood and wood composites. There are some modification techniques, such as thermal treatment, alkali treatment, grafting/coupling agents, and anhydride treatment. The surface of the wood particles will be more hydrophobic, increasing their compatibility with the surface of the polymer matrix. However, chemical modification techniques generally use chemical additives that are not environmentally friendly. Among the modification techniques, thermal treatment, generally varying from 150 to 220 °C, is one of the most commonly used environmentally friendly techniques in the wood and wood composite industry because no chemicals are used in this technique, and it is a simpler method than others. This special issue focuses on improving wood products using thermal modification processes, applications, and their properties.

Wood-polymer composites are increasingly produced through fused deposition modeling (FDM)—an additive manufacturing technique. The versatility of this technology has attracted several industries to print complex shapes and structures. This underscores the importance of studying the mechanical properties of the FDM parts, specifically, their elastic properties. A numerical homogenization methodology is introduced in the present study, focusing on the fundamental aspect of the elastic properties. Investigations were carried out on the influence of various parameters like wood volume fraction, aspect ratio, and internal porosity. The numerical results were validated using analytical models and experimental data. The comparison showed a satisfactory agreement with experimental data, where the relative error did not exceed 10%, leading to a strong conclusion about the validity and effectiveness of the proposed approach.
