  1. 1. Hygroelastic behaviour of wood-fibre based materials on the composite, fibre and ultrastructural level

    Författare :Razvan Cristian Neagu; Kristofer Gamstedt; Staffan Toll; KTH; []
    Nyckelord :wood fibres; ultrastructure; structure-property relations; microfibril angle; composites; characterization methods; hygroelastic properties; micromechanics; modelling; reinforcement potential; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Wood fibres can be used as reinforcement in plastics for load carrying purposes. Some advantages compared with conventional man-made fibres are that wood fibres come from a renewable resource, have high specific stiffness and strength, are generally less hazardous to health, biodegradable, and can be manufactured at low cost and high volumes.

  3. 2. Hygroelastic properties of wood fibres for composite applications

    Författare :Cristian Neagu; Kristofer Gamstedt; Per-Johan Gustafsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Wood pulp fibres are gaining increased use for other applications than paper and board. Wood fibres can also be used as reinforcement in plastics for load carrying purposes. LÄS MER

  4. 3. Modeling the mechanical performance of natural fiber composites

    Författare :Erik Marklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Due to environmental concerns the interest in use of renewable and recyclable materials has dramatically increased over the recent years. Wood and other lignocellulosic fiber reinforced polymers have large potential as structural materials due to the high specific stiffness, high specific strength and high aspect ratio of the fibers.

  5. 4. Structure and Mechanical Behaviour of Wood-Fibre Composites

    Författare :Thomas Joffre; E. Kristofer Gamstedt; Stéphane Avril; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Wood fibres have several advantages compared to man-made synthetic fibres: they have high specific stiffness, are renewable, relatively inexpensive, available in industrial quantities and biodegradable. However, to increase and diversify their utilisation, it is necessary to increase the understanding on what controls their mechanical properties. LÄS MER
