  1. 1. Development and characterisation of bast and basalt fibre hybrid polymer composites for automotive applications

    Författare :Anjum Saleem; Roberts Joffe; Högskolan i Borås; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flax; Hemp; Kenaf; Basalt fibres; Polypropylene; Acrylic based polyester resins; Flexural; Tensile; Impact strength; Resource Recovery; Resursåtervinning;

    Sammanfattning : Natural fibres such as kenaf, hemp, and flax, also known as bast fibres, offer several benefits such as low density, low cost, carbon dioxide neutrality, sustainability and renewability. In Europe, their composites are used intensively by almost all car manufacturers, mostly in interior applications. LÄS MER

  2. 2. Strengthening of timber structures with flax fibres

    Författare :Alann Andre; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The natural defects present in timber are the source of large variations in mechanical properties. This drawback has been partially counteracted with the use of Engineered Wood Products EWP (glulam, composite I-beam, parallel strand lumber, etc.) instead of solid wood. LÄS MER

  3. 3. Mechanical Analysis of Melamine-Formaldehyde Composites

    Författare :Per-Ola Hagstrand; Chalmers University of Technology; []
    Nyckelord :melamine-formaldehyde; damage; composites; alumina trihydrate; stiffness modelling; cyclic loading; rheokinetics; flax fibres; in-situ SEM;

    Sammanfattning : Planar random fibre composite materials based on melamine-formaldehyde (MF), one of the hardest and stiffest isotropic polymers that is known, have been developed recently on an industrial scale. In this thesis the mechanical behaviour of these materials is systematically investigated for the first time. LÄS MER

  4. 4. Benefits of strengthening timber with fibre-reinforced polymers

    Författare :Alann André; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

  5. 5. Renewable Composites Prepared from Biobased Thermoset Resins

    Författare :Dan Åkesson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Renewable; natural fibre; composite; biobased thermoset resin; natural fibres; composites; Energi och material;

    Sammanfattning : In our efforts to create a more sustainable society, several researchers have tried to prepare composites from renewable materials in recent years. The use of natural fibres for reinforcement of composites has been relatively well studied. LÄS MER
