  2. 1. A Study on Sandwich Structures : Development, Mechanical Characterization and Numerical Modeling

    Author : Samuel Hammarberg; Pär Jonsén; Jörgen Kajberg; Simon Larsson; Dan Zenkert; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultra-High Strength Steel; UHSS; Sandwich; Micro-sandwich; Hybrix; Modeling; Composite; Hållfasthetslära; Solid Mechanics;

    Abstract : Legislative demands force the automotive industry to reduce greenhouse gas (GHG) emissions. At the same time, crashworthiness must not be compromised. A ve-hicle’s GHG emissions, such as carbon dioxide, is dependent on its fuel consump-tion. Lowering the vehicle weight, reducing fuel consumption, will therefor reduce emissions. READ MORE

  7. 5. Recyclable self-reinforced ductile fiber composite materials for structural applications

    Author : Christof Schneider; Dan Zenkert; Sohrab Kazemahvazi; Malin Åkermo; Ignace Verpoest; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-reinforced polymer; Composite; sandwich structure; mechanical properties; impact behaviour; finite element; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : Lightweight structures in vehicles are a proven way to reduce fuel consumption and the environmental impact during the use. Lower structural weight can be achieved by using high performance materials such as composites or using the material efficiently as a sandwich structure. READ MORE
