  2. 1. Development of Finite Element Models for 3-D Forming Processes of Paper and Paperboard

    Author : Eric Linvill; Sören Östlund; Johan Tryding; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3-D forming; constitutive model; moisture; temperature; hydroforming; deep drawing; 3-D formning; finitaelement; konstitutiv modell; fukt; temperatur; hydroformning; djup dragning; Hållfasthetslära; Solid Mechanics;

    Abstract : Paper materials have a long history of use in packaging products, although traditional paper-based packaging is limited in its shape and design. In order to enable more advanced paper-based packaging, various 3-D forming processes for paper materials have been studied. READ MORE

  4. 2. The synthesis, surface modification and use of metal-oxide nanoparticles in polyethylene for ultra-low transmission-loss HVDC cable insulation materials

    Author : Amir Masoud Pourrahimi; Ulf W. Gedde; Alexander Bismarck; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; metal-oxide nanoparticles; heat treatment; surface coating; humidity resistance; interfacial adhesion; nanocomposite; HVDC insulation; polyeten; metalloxid nanopartiklar; värmebehandling; ytmodifiering av partiklarna; fukt inverkan; gränsskiktsvidhäftning; nanokomposit; HVDC isolering; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Polyethylene composites which contain low concentrations of metal-oxide nanoparticles e.g. ZnO and MgO are emerging materials for the use in insulations of extruded high-voltage direct-current (HVDC) cables. READ MORE

  5. 3. An Experimental Investigation of Shape Distortions in Aerospace Composites

    Author : Erik Hörberg; Malin Åkermo; Stefan Hallström; Patrik Fernberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flyg- och rymdteknik; Aerospace Engineering;

    Abstract : Composite materials are increasingly used in primary structure of modern commercial aircraft. Its excellent material characteristics enables reduction of structural weight compared to traditional metal solutions and thereby offers reduction of fuel consumption and carbon dioxide (CO2) emissions.

  6. 4. Shape stability of laminated veneer products

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

    Abstract : 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. READ MORE

  7. 5. Redistribution of moisture and ions in cement based materials

    Author : Magnus Åhs; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture redistribution; ion redistribution; cement based materials; hysteresis; sorption isotherm; scanning;

    Abstract : There were two principal objectives for this thesis. The first was to develop a methodology and evaluation model of moisture redistribution in order to make the future relative humidity in a screeded concrete slab predictable. The second objective was to develop a method to determine the critical humidity for ion transport in concrete. READ MORE
