Fracture Toughness of Wood and Wood Composites during Crack Propagation

The mode I fracture toughness as a function of crack length of medium density fiberboard (MDF), particle board (PB), and Douglas-fir (DF) were all measured using a new energy-based method. PB and MDF are examples of composites that develop fiber bridging during crack propagation, which causes their toughness to increase with crack length. Longitudinal cracks in DF also displayed fiber bridging ...

Performance Characterization of Coatings on Treated-wood

Coating performance is greatly influenced by the properties of the wood substrate. This study was focused on evaluating the performance of coatings on both preservative- and thermally-treated wood. A number of commercially formulated semi-transparent stains Alkyd, Alkyd-Acrylic and PU were applied on four different types of preservative treated and heat-treated wood and their performances were ...

Handling of impregnated waste wood and characterization of ash residues after combustion of the wood

In the next ten years the amounts of waste wood impregnated with Cu, Cr and As (CCA) is expected to increase dramatically world wide. CCA has been widely used for wood preservation since the early 1950s and because the fixation of CCA in the wood is good, the concentration of CCA is still high, when the wood is at the end of service. In some countries e.g. Denmark and Norway, the use of As for ...

Strenght and Colour Response of Solid Wood to Heat Treatment

Heat treatment is a method for improving the durability and dimensional stability of wood. The treatment method used in this work is called Thermo Wood and is industrially applied in Finland. In 2004 production was 31146 m. The method involves heating wood in a steam atmosphere where the heat causes chemical changes in the structure of the wood. The present work was done in order to improve the...
