2. 1. Atoms in Lithiated Carbon Fibres

   Author : Marcus Johansen; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lithium insertion; atom probe tomography; synchrotron hard X-ray photoelectron spectroscopy; energy storage; carbon fibres; Auger electron spectroscopy; microstructure; heteroatoms; multifunctional composites;

   Abstract : Carbon fibres are key constituents of structural batteries, in which electrochemical energy storage and mechanical load bearing are merged in one multifunctional device. Here carbon fibres simultaneously act as structural reinforcement by carrying load and as battery electrode by hosting lithium (Li)-ions in its microstructure. READ MORE

4. 2. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets

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

   Abstract : 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. READ MORE

5. 3. 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.

6. 4. On the production of polyethylene dielectrics and conductive polymer composite fibres

   Author : Martin Strååt; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; carbon black; polypropylene; melt spinning; foaming; polystyrene; fibres; cables; carbon nanotubes; electrical properties;

   Abstract : Foamed cable insulations and conductive polymer composite fibres are two applications in polymer processing where the electrical properties of a material may be altered significantly during processing. Their common denominator is that the outcome depends to a large degree on the flow behaviour of the polymer melt, in particular the melt extensional properties. READ MORE

7. 5. Towards the production of conductive and piezoelectric bicomponent textile fibres

   Author : Erik Nilsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polypropylene; Graphite nanoplatelets; bi-component fibres; rheology; conductive fibres; carbon black; PVDF; electrical conductivity; piezoelectric fibres; melt spinning;

   Abstract : In the present study electrical conductive and piezoelectric textile fibres have been manufactured and characterized. Potential applications of these fibres are for example textiles with heating and sensor properties. READ MORE
