  1. 1. Characterization of elastic moduli of single fibres

    Författare :Shanghong Duan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AFM; Nanoindentation; Shear modulus; Transverse modulus; Carbon fibre;

    Sammanfattning : The carbon fibre is one of most promising materials for high-performance composites since it is lightweight and strong. It has been widely used to build carbon fibre reinforced polymer (CFRP) composites. The carbon fibre dramatically reinforces the composite in the fibre direction. LÄS MER

  3. 2. Transverse anisotropy in softwoods : Modelling and experiments

    Författare :Carl S. Modén; Lars Berglund; Lennart Salmén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Softwood; Cellular solid; Anisotropy; Deformation mechanisms; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Transverse anisotropy is an important phenomenon of practical and scientific interest. Although the presence of ray tissue explains the high radial modulus in many hardwoods, experimental data in the literature shows that this is not the case for pine. LÄS MER

  4. 3. Transverse failure initiation in polymer composites

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

    Sammanfattning : Transverse failure is one of the most important failure modes in polymer composites. The phenomenon often causes the first deviations from nonlinear laminate behavior. Also, in pressure vessels and pipes, fluid leakage through a path of transverse cracks is often the limiting design criterion. LÄS MER

  5. 4. Micromechanics of softwoods in the transverse plane : effects on cell and annual ring scales

    Författare :Carl S. Modén; Lars Berglund; Per Johan Gustafsson; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära; Engineering mechanics; Teknisk mekanik; Biomaterials; Biomaterial;

    Sammanfattning : Transverse mechanical properties of wood are important in many practial applications and an interesting scientific subject. A very low transverse shear modulus has been identified in spruce, which causes large strain concentrations in wood structures. LÄS MER

  7. 5. Characterisation of a structural battery composite and its constituents

    Författare :Shanghong Duan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomimetic; carbon fibres; 3D reconstruction.; volume expansion; elastic modulus; characterisation; structural battery electrolyte; structural battery; lithiation;

    Sammanfattning : The structural battery composite is a recently successfully developed multifunctional lithium-ion battery. It is safer and capable to carry mechanical load compared to commercially available liquid electrolyte batteries. LÄS MER
