    Abstract : Degradation of wood is a complex problem dependent on many parameters, but especially the presence of excessive amounts of water causes many problems.The objective of this work was to study the influence of various parameters on water absorption and desorption in Norway spruce (Picea abies (L.) Karst). READ MORE

  2. 2. Bonding veneers using only heat and pressure : focus on bending and shear strength

    Author : Carmen Cristescu; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-bonding; auto-adhesion; LVL; beech; Fagus Sylvatica; high-temperature; pressure; Forestry; agricultural sciences and landscape planning - Wood fibre and forest products; Skogs- och jordbruksvetenskap samt landskapsplanering - Träfiber- och virkeslära; Träteknik; Wood Technology;

    Abstract : A compact laminated board can be obtained by pressing layers of veneers with no other material or substance placed between them. The process does not require the use of steam pretreatment, surface activation methods, a gastight press, friction or adhesives. It strictly involves the heat and the pressure induced by the press in the veneers. READ MORE
