  2. 11. Micromechanical Modelling of Wood and Fibre Properties

    Author : Kent Persson; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Byggnadsteknik; Building construction; Microfibril angle; Density; Hygroexpansion; Stiffness; Simulation; Wood; Fibre; pollution control; Miljöteknik; kontroll av utsläpp; Material technology; Materiallära; materialteknik;

    Abstract : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. READ MORE

  4. 12. Wood-fibre composites : Stress transfer and hygroexpansion

    Author : Karin M. Almgren; Kristofer Gamstedt; Véronique Michaud; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Wood fibres is a type of natural fibres suitable for composite applications. The abundance of wood in Swedish forests makes wood-fibre composites a new and interesting application for the Swedish pulp and paper industry. READ MORE

  5. 13. Fibre reinforced concrete : fracture mechanics methods applied on self-compacting concrete and energetically modified binders

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

    Abstract : Fibre reinforced concrete (FRC) is a type of building material that is increasing in use. As new types on concrete develops the need to update the knowledge on the use of fibre reinforcement increases. This thesis covers test methods for FRC that ranges from standard beam tests to sophisticated uniaxial tension tests. READ MORE

  6. 14. Dimensional Stability of Paper : Influence of Fibre-Fibre Joints and Fibre Wall Oxidation

    Author : Per A. Larsson; Lars Wågberg; Mikael Lindström; Lars Berglund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : Papper är ett mycket mångsidigt material. Trots detta finns det ett flertal egenskaper som begränsar papperets användbarhet. Ett av de större problemen med cellulosa- och lignocellulosafibrer är att de sänker sin fria energi genom att sorbera vatten, och denna sorption förändrar papperets dimensioner. READ MORE

  7. 15. 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
