  1. 6. Wood-fibre composites : Stress transfer and hygroexpansion

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

    Sammanfattning : 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. LÄS MER

  3. 7. Wood fiber composites : from processing and structure to mechanical performance

    Författare :Lars-Olof Nordin; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The work presented in this thesis has been focused on the mechanical properties of wood fiber composites. One goal has been to investigate the processing of wood polymer composite materials with good mechanical properties, and how to tailor these properties for different applications. LÄS MER

  4. 8. Natural fiber composites : optimization of microstructure and processing parameters

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

    Sammanfattning : Natural fiber composites, (NFC) are defined in this work as a group of materials where at least the fibers originates from renewable and CO2 neutral resources. NFC consists of a polymer matrix and a natural fiber. The fibers which originate from wood or plants can replace non-renewable fibers or fillers or simply replace part of the plastic. LÄS MER

  5. 9. Lightweight multifunctional composites : An investigation into ion-inserted carbon fibres for structural energy storage, shape-morphing, energy harvesting & strain-sensing

    Författare :Ross Harnden; Dan Zenkert; Paolo Ermanni; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flyg- och rymdteknik; Aerospace Engineering;

    Sammanfattning : The transport sector accounts for around 26% of all greenhouse gas emissions in the European Union and United Kingdom. By reducing the mass of vehicles it is possible to reduce these emissions substantially.One way to reduce vehicle mass is to use multifunctional structures. LÄS MER

  7. 10. Wood fiber composites : processing, structure and properties

    Författare :Lars-Olof Nordin; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The goal of this work has been to investigate how to make wood polymer composite materials with good mechanical properties, which also could be tailored for different applications. The fundamental idea behind the work was that good mechanical properties of the composite material require that the stiffness and strength of the wood cell wall material are really utilized. LÄS MER
