  1. 11. Application of a Sandwich Construction on a Superstructure of a High Speed Ferry

    Author : Gaurav Ahuja; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; catamaran; pitch connecting moment; carbon fibre; natural frequency analysis; light weight structure; structural optimisation.; torsional moment; glass fibre; Sandwich construction; finite element analysis;

    Abstract : Usage of light weight materials has gained momentum in the marine market in the last few decades. This rise has lead to some ships using parts fabricated out of materials like glass and carbon fibre. READ MORE

    Author : Andreas Bengtsson; Monica Ek; Maria Sedin; Elisabet Brännvall; Elisabeth Sjöholm; Johannes Ganster; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Carbon fiber; Carbonization; Cellulose; Kraft pulp; Softwood kraft lignin; Solution spinning; Stabilization; Barrvedslignin; Cellulosa; Karbonisering; Kolfiber; Lösningsmedelsspinning; Stabilisering; Sulfatmassa; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Carbon fibers (CFs) have excellent mechanical properties and a low density, making themattractive as a reinforcing fiber in composites. The use of CFs is limited to high-end applications,since they are produced from an expensive fossil-based precursor via an energy-intensivemanufacturing process, explaining the need for cheaper CFs from renewables.

  3. 13. Lithium-intercalated Carbon Fibres : Towards the Realisation of Multifunctional Composite Energy Storage Materials

    Author : Eric Jacques; Dan Zenkert; Göran Lindbergh; Milo Shaffer; KTH; []
    Keywords : Flyg- och rymdteknik; Aerospace Engineering;

    Abstract : Lightweight design is a major improvement path for sustainable transport asit contributes to lower vehicles energy consumption and gas emissions. Anovel solution to weight savings is to store energy directly in the mechanicalstructure of the vehicle with a multifunctional material, called structural battery,which could simultaneously bear mechanical loads and store electricalenergy.

  4. 14. Studies of Dielectric Relaxation in Solid Polymers and Composites

    Author : Mohsen Safari Ardi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dielectric permittivity; time-domain dielectric relaxation; composite; carbon black; poly vinylidene fluoride ; interfacial polarization; poly vinyl chloride ; coated carbon fibre; epoxy; poly methyl methacrylate ; nitrile butadiene rubber; ethylene-vinyl acetate copolymer; polyamide 6;

    Abstract : Non-linear characteristics of homogeneous solid polymers and solid polymer-based composites have been studied both experimentally and theoretically. In particular experimental studies of non-linear dielectric response of six homogeneous solid polymeric materials and the influence of the composition on the properties of solid polymer-based composites with high dielectric permittivities have been carried out and a theoretical study of dipole-dipole interaction in solids based on a formulation due to P.

  5. 15. Strengthening of concrete beams using cementitious carbon fibre composites

    Author : Anders Wiberg; KTH; []
    Keywords : civil; materials science; textile technology;

    Abstract : The research described in this thesis deals with the use ofcement-based carbon fibre reinforced composites forstrengthening of existing structural concrete. There is a large world-wide need for simple and reliablemethods to repair and strengthen aging infrastructure andbuildings. READ MORE
