  1. 6. Influence of liquid diffusion on the performance of polymer materials in industrial applications

    Författare :Stefanie Römhild; Mikael Hedenqvist; Lars Berglund; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LCP; Vectra A950; thermoset resin; FRP; diffusion; disclination; annealing; lining; bonding; long-term properties in water; Polymer chemistry; Polymerkemi;

    Sammanfattning : Diffusion of liquids into and through polymers is an important factor that negatively may influence the durability or lifetime of a polymer structure used in industrial applications. In this work two types of polymers, a liquid crystalline polymer (LCP, Vectra A950) and various thermoset resins as used in fibre reinforced plastics (FRP) process equipment were studied with regard to barrier properties, chemical resistance and long-term performance.

  3. 7. Synthesis and characterisation of thermoset-clay nanocomposites

    Författare :Xavier Kornmann; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Polymer-clay nanocomposites are materials reinforced on a molecular scale by 1 nm-thick clay layers dispersed in a polymer matrix. Thermoset-clay nanocomposites were synthesised from unsaturated polyester and epoxy resins with two different approaches. LÄS MER

  4. 8. Electron-beam curing of thermoset resins for composites

    Författare :Thierry Glauser; KTH; []
    Nyckelord :;

    Sammanfattning : Electron-beams (EB) are an alternative to traditionalthermal curing when manufacturing thick thermoset composites.It is a quick and energetically efficient technique when curinglarge fiber reinforced parts. Most of the published work onEB-curing deals with curing of thin layers of resin or withcrosslinking of polymers. LÄS MER

  5. 9. Properties and performance of regenerated cellulose thermoset biocomposites

    Författare :Sunil Kumar Ramamoorthy; Jyrki Vuorinen; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; regenerated cellulose fibres; surface modification; alkali; silane; mechanical analysis; biocomposites; renewable resources; Resursåtervinning; Resource Recovery;

    Sammanfattning : Biocomposites have been developed to address the sustainability issues of nonrenewableresource based materials. These composites are often produced by reinforcing natural fibres in petroleum based thermoset resins or thermoplastic polymers. LÄS MER

  7. 10. Synthesis and characterisation of thermoset-layered silicate nanocomposites

    Författare :Xavier Kornmann; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : Thermoset-layered silicate nanocomposites are materials reinforced on a molecular scale by 1 nm-thick silicate layers of high aspect ratio dispersed in a thermoset matrix. These new materials were synthesised from unsaturated polyester and several epoxy resins (DGEBA/diamines and TGDDM/DDS) using two different approaches. LÄS MER
