  1. 6. Wood fiber composites : from processing and structure to mechanical performance

    Författare :Lars-Olof Nordin; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The work presented in this thesis has been focused on the mechanical properties of wood fiber composites. One goal has been to investigate the processing of wood polymer composite materials with good mechanical properties, and how to tailor these properties for different applications. LÄS MER

  3. 7. Improved mechanical properties of a polar polythiophene through copolymerization or blending with urethanes

    Författare :Sepideh Zokaei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conductive fibers; polar conjugated polymers; mechanical properties;

    Sammanfattning : Polar polythiophenes with oligoethylene glycol side chains are a developing class of materials that are great candidates for energy harvesting and storage as well as bioelectronics. The polar side chains enhance the compatibility with molecular dopants and improve the electrical conductivity and thermal stability of the doped material. LÄS MER

  4. 8. Tensile behaviour of mineral-based composites

    Författare :Katalin Orosz; Anders Ansell; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : Externally bonded fibre-reinforced polymer (FRP) systems have shown to be a robust and durable way to repair, or strengthen concrete structures. Epoxy, as the most common bonding agent, provides excellent force transfer, and bonds well to the base substrate to the as well as to the strengthening material. LÄS MER

  5. 9. Electronic Waste Plastics Characterisation and Recycling by Melt-processing

    Författare :Erik Stenvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; melt-blending; WEEE; ternary polymer blend; processing conditions; plastics recycling; composition analysis; e-waste;

    Sammanfattning : Melt-processing of blended plastics from waste electrical and electronic equipment (WEEE) is a method to facilitate mechanical recycling, and this might improve the recycling conditions and increase the amounts of plastics being recycled. To ensure the quality of melt-blended plastic waste, it is essential to know the composition of the incoming material and then possibly improve the compatibility between the different polymer phases.

  7. 10. Natural fibres/polypropylene composites from residual and recycled materials

    Författare :Ana Espert; KTH; []
    Nyckelord :;

    Sammanfattning : Natural fibres fulfil all the requirements in order toreplace inorganic fillers in thermoplastic composites. Naturalfibres are inexpensive, renewable, biodegradable, present lowerdensity and their mechanical properties can be compared tothose of inorganic fillers. However, several disadvantagesappear when natural fibres are used for composites. LÄS MER
