  1. 21. Tribology of polymer composites for elevated temperature applications

    Författare :Jonna Lind; Åsa Kassman Rudolphi; Stefan Silverbåge; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; polymer composite; friction; wear; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Sammanfattning : Polymers as construction material are common in the industry. Although more recently the use of polymer composites in more demanding applications has increased, requiring more of them mechanically, tribologically and thermally. To enhance the properties various fillers are used, from common glass fibers to more advanced nanoparticles. LÄS MER

  3. 22. Innovative Water-Resistant Fire-Retardant Wood incorporating Ammonium Phosphate-based salts for Exterior Use Conditions

    Författare :Chia-Feng Lin; Olov Karlsson; Dick Sandberg; George Mantanis; Dennis Jones; Bartłomiej Mazela; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

    Sammanfattning : Wood is a naturally based material and plays an important role as a renewable resource when aiming for a sustainable society. Nevertheless, its inherently combustible property needs to be enhanced to comply with modern construction methods and regulations. LÄS MER

  4. 23. Creep aspects of softwood from the cell-wall level to structures

    Författare :Rhodel Bengtsson; E. Kristofer Gamstedt; Mahmoud Mousavi; Reza Afshar; Falk Wittel; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Creep; Solid Mechanics; Wooden Materials; Linear Viscoelasticity; Experiments; Materialvetenskap; Materials Science;

    Sammanfattning : This thesis addresses the intricate mechanical behaviour of natural materials, with a particular focus on wood. Despite millennia of use, understanding the mechanical behaviour of wood materials remains challenging due to their complex microstructures. LÄS MER

    Sammanfattning : The objects of this PhD thesis are Southern Swedish painted wall-hangings: folk art paintings from the 18th and 19th centuries. The aim and objective of the study are: to investigate the construction and manufacturing processes of the painted wall-hangings; to identify both the painting materials and other substances employed; and, to document painting techniques used by different painters within this painted wall-hanging tradition.
