  2. 21. Micromechanics of Powder Compaction

    Author : Erik Olsson; Per-Lennart Larsson; Christophe Martin; KTH; []
    Keywords : Hållfasthetslära; Solid Mechanics;

    Abstract : Compaction of powders followed by sintering is a convenient manufacturing method for products of complex shape and components of materials that are difficult to produce using conventional metallurgy. During the compaction and the handling of the unsintered compact, defects can develop which could remain in the final sintered product. READ MORE

  4. 22. A study of wood adhesion and interactions using DMTA

    Author : Anna Backman Sandlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Abstract : The aim of the work presented in this thesis was to investigate whether the adhesion of glues and lacquers to wood could be studied using dynamic mechanical thermal analysis (DMTA). This method has been widely used to study interactions in polymer blends, copolymers and in polymeric composites but very few investigations had been done on solid wood. READ MORE

  5. 23. Adhesion and Nanotribology of Biofibres

    Author : Hiroyasu Mizuno; Mark Rutland; Nicholas Spencer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The fibre probe atomic force microscope is developed, which allows direct measurement of force and friction between single fibres at the nanoscale under various conditions. In this work, polyester and human hair fibres were used as being representative of synthetic and animal fibre. READ MORE

  6. 24. The Influence of Molecular Adhesion on Paper Strength

    Author : Malin Eriksson; Lars Wågberg; Orlando Rojas; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi;

    Abstract : This thesis deals with the influence of molecular adhesion on paper strength. By combining the use of high-resolution techniques and silica/cellulose surfaces, with various fibre–fibre and sheet testing techniques, new information regarding the molecular mechanisms responsible for paper strength has been obtained.

  7. 25. High Temperature Tribology of Aluminium : Effect of Lubrication and Surface Engineering on Friction and Material Transfer

    Author : Justine Decrozant-Triquenaux; Jens Hardell; Manel Rodriguez Ripoll; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Abstract : Lightweight design for automotive applications has been pursued for several decades and continues to increase. The main driving forces are new and increasingly stringent emission regulations as well as the increasing popularity of electric, or hybrid, vehicles where the increased weight of the batteries need to be compensated by light weight structures.
