    Sammanfattning : Thermally modified timber (TMT) has gained market share in Europe as an environmentally friendly and durable building material. Unfortunately, TMT products are currently prohibited for use in structural applications as there is insufficient data to estimate the loss in strength due to thermal modification. LÄS MER

    Sammanfattning : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. LÄS MER

  3. 3. The measurement of compression wood and other wood features and the prediction of their impact on wood products

    Författare :Micael Öhman; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Wood is a complex and highly variable biological material formed to give the tree best possible conditions for sustaining life. Thus every piece of wood is possessed of unique qualities. LÄS MER

  4. 4. Outsourcing in the Wood Product Manufacturing Sector A Combined Customer and Supplier Perspective

    Författare :Daniel Nordigården; Staffan Brege; Jakob Rehme; Dan Andersson; Lars Bengtsson; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Outsourcing; driving forces; forward integration; supplier value-adding strategies; parallel production; wood products and sawmills; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

    Sammanfattning : Outsourcing can be defined as transferring an activity from internal to external control. This thesis studies outsourcing in the wood product manufacturing (WPM) sector from both a customer and supplier perspective. LÄS MER

  5. 5. Automatic measurement of compression wood and spiral grain for the prediction of distortion in sawn wood products

    Författare :Jan Nyström; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : Distortion is one of the major obstacles for effective utilisation of wood, especially in the building process, where wood has lost market shares to other materials largely because of the lack of straightness. Bow and spring are often caused by compression wood, while twist is the cause of spiral grain. LÄS MER
