Mineral-wood composites with improved fire properties and durability prepared through MgCO3-based mineralization
2025 - IRG/WP 25-30823
New mineral-wood composites that demonstrate improved fire properties and higher resistance to selected fungi have been prepared using an environmentally-friendly mineralisation process involving impregnation with an aqueous magnesium acetoacetate solution. MgCO3-based compounds are formed in situ, deep within the wood’s structure. We show that the new mineralisation method overcomes wood’s lo...

Process Development in Continuous Wood Densification and the Influence of Ionic Liquids on Set-Recovery and Mechanical Properties
2025 - IRG/WP 25-30827
The densification of wood significantly enhances its mechanical properties, making low-density species more viable for high-performance applications. However, challenges such as set-recovery (SR) and production speed hinder large-scale adoption. This study investigates continuous surface densification using a custom-built belt press and examines the effect of chemical pre-treatment with ionic liqu...

Investigation of Impregnation Factors for Biomass-Based Phenol-Formaldehyde Resins
2025 - IRG/WP 25-41044
This study investigates the impregnation factors affecting the treatment of wood with biomass-based phenol-formaldehyde (PF) resins, such as impregnation methods, resin properties, and setting parameters like time and pressure. The goal is to ensure effective resin penetration into the wood cell wall structure, thereby enhancing wood durability and mechanical properties. Previous literature has la...
