  1. 1. Carbon fibres from lignin-cellulose precursors

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andreas Bengtsson; KTH.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon fibre; Kraft lignin; Cellulose; Dry-jet wet spinning; Kolfiber; Sulfatlignin; Cellulosa; Våtspinning; Luftgapsspinning; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : It is in the nature of the human species to find solutions of complex technical problems and always strive for improvements. The development of new materials is not an exception. One of the many man-made materials is carbon fibre (CF). READ MORE

  2. 2. Cellulose–Assisted Dispersion of Carbon Nanotubes : From Colloids to Composites

    University dissertation from KTH Royal Institute of Technology

    Author : Alireza Hajian; KTH.; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanocelluloses; Carbon nanotubes; Composites; Colloids; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : It is a challenge to disperse nanoparticles to obtain a nanostructured composite. This thesis aims at providing a new route to fabricate carbon nanotube (CNT) composites and suggests mechanisms for nanocellulose–CNT interactions. This route is based on unmodified CNT dispersed in water with the help of nanocellulose. READ MORE

  3. 3. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets

    University dissertation from KTH Royal Institute of Technology

    Author : Björn Voigt; [2004]
    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

  4. 4. Benefits of strengthening timber with fibre-reinforced polymers

    University dissertation from KTH Royal Institute of Technology

    Author : Alann André; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental results; Carbon; Timber; Tension perpendicular to the grain; Ductility; Flax; Reinforcement; Compression failure parallel to the grain; Kinkband; Composite materials; Numerical model; Analytical model; FRP;

    Abstract : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. READ MORE

  5. 5. Application of a Sandwich Construction on a Superstructure of a High Speed Ferry

    University dissertation from KTH Royal Institute of Technology

    Author : Gaurav Ahuja; [2007]
