  2. 1. Manufacture of long-fibre reinforced ceramics by reaction bonding

    Author : Jesper Brandt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; weaves; slurry infiltration; fibre; aluminium oxide; reaction bonding; ceramic matrix composite; mullite; silicon nitride; alumina; CMC;

    Abstract : For several decades ceramic matrix composites has been of interest to be used as hot parts in certain high-performance gas turbine aero engines. In general, ceramic materials resist higher temperatures than superalloys. READ MORE

  4. 2. Crying Rya: A Practitioner’s Narrative Through Hand Weaving

    Author : Emelie Röndahl; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; rya; hand weaving; crafts; time; two-sidedness; reflective practice; bodily knowledge; craft research; artistic research;

    Abstract : This research project examines a repeated focus on time and slowness that I have experienced over years in connection with my hand-weaving practice using the Scandinavian technique of rya. Research through my own studio practice has led me to question a public image of weaving as time-consuming or slow and why temporality is attributed to the finished object, while I claim that it is only experienced in the making process.

  5. 3. Testing and analysis of composites with 3D woven reinforcement

    Author : Tomas Ekermann; Malin Åkermo; Stefan Hallström; Lars Pilgaard Mikkelsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D weave; finite element; manufacturing; yarn path; weaving; failure criteria; mechanical testing; 3D väv; finita element; tillverkning; trådbanor; vävning; brottkriterier; mekanisk provning; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Composites with three-dimensional (3D) reinforcement have several benefits, compared to laminated composites. Their through-thickness reinforcement increase the out-of-plane properties significantly and could eliminate problems with delaminations. Also, these composites have proven to have great damage tolerance and energy absorption. READ MORE

  6. 4. 3D-woven Reinforcement in Composites

    Author : Fredrik Stig; Stefan Hallström; Dan Zenkert; Andrew Long; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Composites made from three-dimensional (3D) textile preforms can reduce  both the weight and manufacturing cost of advanced composite structures  within e.g. aircraft, naval vessels and blades of wind turbines. READ MORE

  7. 5. Hydrodynamics of plane liquid jets aimed at applications in paper manufacturing

    Author : Daniel Söderberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid jet; transition; break-up; stability; wavelet; free surface; waves; streamwise streaks; fibre suspension; headbox; forming; shadowgraph; hot-film; Engineering mechanics; Teknisk mekanik;

    Abstract : Process industries are in general depending, in one way or the other, on fluid mechanics.Specifically, paper manufacturing, which probably is the dominant processindustry in Sweden, is depending on the flow of cellulose fibres suspended in water. READ MORE
