1. 1. Mechanics of Cross-Laminated Timber

   Författare :Dietrich Buck; Olle Hagman; Dick Sandberg; Mats Ekevad; Mikael Sjödahl; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CLT assembly; CLT manufacture; Crosslam; DIC analysis; Digital speckle photography; Full-field mechanics; Laminated wood product; Mass timber engineering; Non-contact measurement; Non-destructive; Optical measurement; Panel configuration; Strain localization; X-lam; Alternativ byggmetod; Bildkorrelation; Hållbart byggande; KL- trä; Korslimmat trä; Skjuvtöjning; Massivträ; Träkonstruktion; Träteknik; Wood Science and Engineering;

   Sammanfattning : Increasing awareness of sustainable building materials has led to interest in enhancing the structural performance of engineered wood products. Wood is a sustainable, renewable material, and the increasing use of wood in construction contributes to its sustainability. LÄS MER

3. 2. Acetylation of Solid Wood. Wood Properties and Process Development

   Författare :Pia Larsson Brelid; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microwave heating; deformation; wood; hardness; adhesive bonding; power penetration depth; shear strength; delamination; acetylation; pH; bending strength; dielectric properties; stability;

   Sammanfattning : The influence of acetylation on selected wood properties has been determined for Scandinavian pine and spruce wood, in order to predict the behavior of acetylated wood when it is used in different applications. Only minor differences in both bending strength and the modulus of elasticity were obtained for acetylated wood when compared with unmodified wood, and can, for practical applications, be considered unaltered.

4. 3. Moisture Transport and Moisture-Induced Distortions in Timber - an Experimental and Numerical Study

   Författare :John Eriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat transfer; gluing; twist; drying; wood; timber board; laminated product; FEM; distortion; moisture; mass transfer;

   Sammanfattning : Timber products subjected to climatic variations commonly display moisture-induced distortions that can lead to serious problems for end-users. The aim of the thesis, which consists of an extended summary and six appended papers, was to investigate the potential of using the gluing technique suggested here for dealing with problems of moisture-induced distortions and developing the heat and mass transfer models which such distortion analyses require.

5. 4. Studies on the competitiveness of wood : - market segmentation and customer need assessments

   Författare :Ragnar Jonsson; Roger Cooper; Växjö universitet; []
   Nyckelord :wood; building material; material substitution; end-consumer; floorcovering; customer needs; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING;

   Sammanfattning : Over the last decades, wood has encountered increasing competition from other building materials. Hence, it is relevant to study the underlying factors of material substitution. The market for repair and remodelling (R&R) is growing in importance. LÄS MER

7. 5. Shape stability of laminated veneer products

   Författare :Lars Blomqvist; Dick Sandberg; Jimmy Johansson; Magdalena Sterley; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adhesive; beech; birch; bending; laminated veneer products; moulding; shape stability; spring-back; twist; veneer; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : This thesis is about the shape stability of laminated veneer products.Laminated veneer products consist of veneers bonded together with adhesive into a predetermined shape. Such products are used in several contexts but especially in furniture manufacture. LÄS MER
