  1. 1. Fibre reinforced polymers in civil engineering : flexural strengthening of concrete structures with prestressed near surface mounted CFRP rods

    Författare :Håkan Nordin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Repair and/or upgrading of concrete structures with bonded steel or FRP (Fiber Reinforced Polymers) materials or by use of external tendons have been used for some time. In most cases the bonded on FRP materials are unstressed. LÄS MER

  3. 2. Benefits of strengthening timber with fibre-reinforced polymers

    Författare :Alann André; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental results; Carbon; Timber; Tension perpendicular to the grain; Ductility; Flax; Reinforcement; Compression failure parallel to the grain; Kinkband; Composite materials; Numerical model; Analytical model; FRP;

    Sammanfattning : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. LÄS MER

  4. 3. Induction heating of carbon fibre reinforced polymer composites : Characterization and modelling

    Författare :Fredrik Lundström; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon fibre reinforced polymers; Induction heating; Material characterization; Thermal properties; Electrical conductivity; Numerical modelling;

    Sammanfattning : Carbon fibre reinforced polymers (CFRP) are lightweight materials with great potential due to their high strength and stiffness relative to their weight. This enables weight reduction in, for example, vehicles, which is important in reducing energy consumption. LÄS MER

  5. 4. Carbon fibre reinforced polymers for strengthening of structural elements

    Författare :Anders Carolin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : There is a large need for strengthening of concrete structures all around the world. There can be many reasons for strengthening, increased loads, design and construction faults, change of structural system, and so on. The need exists for both strengthening in flexure as well as in shear. LÄS MER

  7. 5. Industrial Bridge Engineering -Structural developments for more efficient bridge construction

    Författare :Peter Harryson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; product and productivity developments; materials developments; Keywords: Bridges; fibre-reinforced polymers.; industrial construction process; steel-fibre-reinforced ultra-high-performance concrete; design; structural joints; structural developments;

    Sammanfattning : In recent years, growing concern about the deficiencies and lack of efficiency in the construction industry has highlighted the need of research in order to make substantial improvements, rectify incongruities and succeed in progressive development. For bridges, the advantages that can be expected from an industrial construction process are especially interesting. LÄS MER
