Thermal conductivity and water vapour transmission properties of wood-based materials

For several wood-based materials (plywood, OSB, melamine faced board (MFB), particle board and fibre board), the thermal conductivity was determined as a function of the temperature (ranging between 10 and 30 °C) and also the moisture content (from an oven-dry sample up to a moisture content at 80% RH). Furthermore, the water vapour resistance factor of these materials as well as of the coating (at MFB) and the diffusion coefficient were determined under dry cup (performance at low humidity dominated by vapour diffusion) and wet cup (performance at high humidity with liquid water and vapour transport) conditions. Thermal conductivity increases with rising temperature, moisture content and density. Moreover, a clear decrease of thermal conductivity was found with decreasing particle size at the same density level, from solid wood over plywood and particle board to fibre board. The water vapour resistance factor of the wood-based materials increases with rising density and decreases with increasing moisture content. An influence of the particle and fibre board thickness was also revealed. In contrast to the remaining materials, an increase of the water vapour resistance factor with increasing moisture content was measured for the coating. The diffusion coefficient decreases with rising density and moisture content.

Flüssigbeschichtung von Möbel-Spanplatten: Oberflächeneigenschaften der Rohplatten,Prüfmethoden,Applikationen, Bewertung der Beschichtung

To evaluate the suitability of particle board for lacquering, 12 different surface properties of 17 industrially produced particle boards, as well as the respective testing methods were investigated. Some new and unconventional methods were applied, such as the indication of the pore percentage by the “bearing portion”, measured by means of a special roughness tester, and the determination of the board density by gamma radiation. After industrial application by scraper priming, sanding and curtain coating, the test specimens were subjected to climatic cycling (storing in standard (20 65) and humid climatel. Only after this treatment the changes in the gross-board-shape and their refation to the board type became obvious. The range of these changes, between the two states of moisture content, could possibly be taken as a criterion to determine the suitability of a certain particle board for a special type of coating.     

Analysing orthotropy in the core layer of wood based panels by means of fracture mechanics

In this study the orthotropic properties in the core layer of wood based panels are analyzed by means of the newly developed double cantilever I beam testing system. Four different wood based panels (i.e., OSB, particle board, particle board containing recycling chips and MDF) were tested in-plane, in longitudinal and lateral orientation. Specific fracture energy numbers yielded significant differences between the longitudinal and the lateral orientation for OSB, while the stress intensity factor analysis showed significant differences for OSB and particle board containing recycling particles.     

Einfluß der Holzart und der Holzartenmischung auf die mechanischen Eigenschaften von Spanplatten bei Verwendung chilenischer Hölzer

The influence of Chilean wood species and mixtures of the same species on particleboard properties was studied. Species and mixture ratio had a great influence on board properties. It was also determined that bending strength and internal bond of particle board from wood mixtures can be calculated using the recorded strength of particle boards based on single wood species.
