  1. 11. Effect of Degree of Cure on Viscoelastic Behavior of Polymers and their Composites

    Författare :Sibin Saseendran; Janis Varna; Anders Sjögren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Viscoelasticty; Curing; Epoxy; Polymeric Composite Materials; Polymera konstruktionsmaterial;

    Sammanfattning : Reinforced polymer composites consist of continuous fibers embedded in a polymer matrix. The matrix is usually a thermoplastic or thermosetting resin. LÄS MER

  3. 12. Laboratory Seismic Testing of Asphalt Concrete

    Författare :Anders Gudmarsson; Nils Rydén; Björn Birgisson; Hervé Di Bendetto; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Nondestructive laboratory seismic testing to characterize the complex modulus and Poisson’s ratio of asphalt concrete is presented in this thesis. These material properties are directly related to pavement quality and the dynamic Young’s modulus is used in thickness design of pavements. LÄS MER

  4. 13. A theoretical investigation of Tin+1AlCn and Mn2GaC MAX phases : phase stability and materials properties

    Författare :Andreas Thore; Johanna Rosén; Björn Alling; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis presents theoretical research on MAX phases (M=transition metal, A=A-group element, X=carbon and/or nitrogen), with focus on predictions of phase stability as well as of physical properties.The first part is an investigation of the phase stability of the MAX phases Ti2AlC, Ti3AlC2, and Ti4AlC3 at elevated temperatures, where the former two phases have been obtained experimentally.

  5. 14. A novel composite material from recycled constituents

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

    Sammanfattning : The increasing industrial use of carbon fibre in e.g. aircraft and wind turbines calls for strategies for their recovery and possible reuse. In additional, tremendous amount of energy is needed to be able to manufacture pristine carbon fibres. LÄS MER

  7. 15. Material parameters and defects in anisotropic plates determined by hologram interferometry

    Författare :Karl-Evert Fällström; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental Mechanics; Experimentell mekanik;

    Sammanfattning : Material parameters and defects in composite plates are determined in a non-contacting and nondestructive way by use of optical methods. Material parameters are determined from TV-holography images, and defects are detected by holographic interferometry with a double pulsed laser as the light source. LÄS MER
