Use of industrially produced thermally modified wood residues for production of wood plastic composites: Summary of the doctoral thesis
2022
Kuka, Edgars
The aim of the Thesis is to characterise TM wood residues and obtain WPC with improved water resistance, as well as to clarify the advantages and disadvantages of these composites, in-depth studying and explaining the causes of the changes in the properties. The main tasks of the Thesis are covered in five points: 1. To describe TM wood residues (particle size distribution, chemical composition, length/diameter ratio, etc.) depending on the wood species, thermal modification method and intensity. 2. To study the impact of TM wood residues on the physical and mechanical properties of WPC (density, impact strength, bending properties, surface microhardness, water absorption, etc.). 3. To study the impact of TM wood residues on the performance of WPC (resistance to weathering processes, biological resistance, water resistance, etc.). 4. To analyse and try to explain the results obtained by conducting in-depth research by various methods appropriate for these purposes (SEM, LSM, UV-Vis, etc.). 5. To investigate the possibility of improving the WPC properties by changing the composition.
