  2. 1. Continuous Fibre Reinforced Oxide/Oxide Composites

    Author : Magnus Holmquist; Chalmers University of Technology; []
    Keywords : polycrystalline oxide fibre; zirconia; single crystal oxide fibre; hot isostatic pressing; hot pressing; alumina; mullite; sapphire; tape casting; interface; VibroIntrusion; interphase; continuous fibre reinforced ceramic composite; mechanical properties; oxide fibre; ceramic matrix composite;

    Abstract : The appealing properties of ceramics include retention of strength and hardness at high temperatures, chemical inertness and low density. However, monolithic ceramics fail in a brittle, unpredictable manner making them unsuitable for many applications where reliability is a key requirement. READ MORE

  4. 2. Flow of pulp suspensions at low shear rates

    Author : Tomas Wikström; Chalmers University of Technology; []
    Keywords : fibre diameter; temperature; computational fluid dynamics; consistency; coarseness; wood species; pH; pulp suspension; fibre length; sonar doppler; agitation; Bingham model; yield stress;

  5. 3. Viscous Behaviour of Fibre-filled Liquids

    Author : Mina Djalili-Moghaddam; Chalmers University of Technology; []
    Keywords : viscosity; geometry effects; short-range interactions; parallel plate; fibre suspension; normal force; cone and plate;

    Abstract : Process simulation of discontinuous fibre composites is of importance in automotive industries. The performance of a fibre composite part depends to a great extent on the fibre orientation pattern. READ MORE

  6. 4. Steel fibre corrosion in cracks : durability of sprayed concrete

    Author : Erik Nordström; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Steel fibre reinforced sprayed concrete is common practice for permanent linings in underground construction. Today there is a demand on "expected technical service life" of 120 years. Thin steel fibres could be expected to discontinue carrying load fast with a decrease of fibre diameter caused by corrosion, especially in cracks. READ MORE

  7. 5. Durability of sprayed concrete : steel fibre corrosion in cracks

    Author : Erik Nordström; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : A combination of sprayed concrete technique and steel fibre technology gives obvious advantages when saving the work needed to place conventional reinforcement. In rock strengthening applications this is most accentuated. Sprayed concrete in general, made by skilled workmen, will generally be of high quality and good durability. READ MORE
