   Sammanfattning : Lightweight energy storage is a must for increased driving range of electric vehicles. “Mass-less” energy storage can be achieved by directly storing energy in structural components. LÄS MER

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

   Författare :Mohsen Safari Ardi; Chalmers tekniska högskola; []
   Nyckelord :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;

   Sammanfattning : 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. 14. Strengthening of concrete beams using cementitious carbon fibre composites

   Författare :Anders Wiberg; KTH; []
   Nyckelord :civil; materials science; textile technology;

   Sammanfattning : 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. LÄS MER

7. 15. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets

   Författare :Björn Voigt; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melamine-formaldehyde; carbon black; phenol-formaldehyde; shungite; mechanical and electrical properties; carbon fibres;

   Sammanfattning : In view of the excellent properties of carbon fibres (CF) and the growing demand for multi-functional materials e.g., electrically conductive composites, engineering thermosets with carbon fibres are highly attractive. Similarly, electrically conductive fillers are of great importance. LÄS MER
