  1. 21. Inelastic analysis of fiber reinforced polymeric composites

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

    Sammanfattning : Fiber reinforced polymer composites are seeing increased use in the outomotive industry and other applications. This is because of the potential for rational and economical production in large series of complex shaped parts. Properties such as high strength to weight ratio and superior impact properties are of particular interest. LÄS MER

  5. 24. Polymeric Materials for Bearing Applications : Tribological Studies in Lubricated Conditions

    Författare :Arash Golchin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

    Sammanfattning : One of the most important demands in hydropower and other industries today stems from the emphasis on preserving the environment. Usage of mineral and synthetic oils in sliding bearings of hydropower plants raises concerns about the environmental impact of these lubricants in case of spillage into downstream water. LÄS MER

  7. 25. Freeze-Dried Wheat Gluten-Based Foams

    Författare :Thomas Blomfeldt; Mikael Hedenqvist; Delcour Jan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Wheat gluten; Glutenin; Gliadin; Renewable; Freeze-drying; Pore structure; Baceterial cellulose; Glycerol; Mechanical properties; Thermal conductivity; Combustion properties;

    Sammanfattning : This thesis presents wheat gluten foams as an alternative to the available commercialfoams. Polymeric foams, like all plastics, are mostly made from petroleum, and this isaffecting the environment negatively with the emission of greenhouse gases and generation oflandfills. LÄS MER
