    Sammanfattning : Bio-basedcomposites are being increasingly used in applications where weight saving,and environmental friendliness is as important as structural performance. Obviously, bio-based materials have their limitations regarding durability and stability of the properties,but their potential in use for advanced applications can be expanded if they were functionalized and considered beyond their structural performance.

  4. 3. Development of New Multiscale Polymer Composites for Water Lubricated Tribological Contacts

    Författare :Hari Shankar Vadivel; Nazanin Emami; Sujeet Kumar Sinha; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UHMWPE; Tribology; Composite; Friction; Wear; Tensile; Creep; Ageing; Machine Elements; Maskinelement;

    Sammanfattning : Moving towards a Green Economy, there is a growing demand to use environmentally friendly tribological systems that has resulted in industries turning towards new mate-rials and water-based lubrication to satisfy their needs. Considering the low viscosity of water, tribological contacts lubricated with it are likely to operate in boundary/mixed lubrication regime for relatively long periods. LÄS MER
