1. 11. Kinetic Energy Storage and Magnetic Bearings : for Vehicular Applications

   Författare :Johan Abrahamsson; Hans Bernhoff; Urban Lundin; Richard Magdalena Stephan; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flywheel; magnetic bearing; energy storage; electric vehicle; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

   Sammanfattning : One of the main challenges in order to make electric cars competitive with gas-powered cars is in the improvement of the electric power system. Although many of the energy sources currently used in electric vehicles have sufficientlyhigh specific energy, their applicability is limited due to low specific power. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER

7. 15. Technical cost modelling and efficient design of lightweight composites in structural applications

   Författare :Mathilda Karlsson Hagnell; Malin Åkermo; Dan Zenkert; Gerhard Ziegmann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technical cost modelling; composite materials; carbon fibre; lightweight design; optimization; Vehicle and Maritime Engineering; Farkostteknik;

   Sammanfattning : A lightweight transport design reduces fuel costs and emissions and can be achieved through the use of fibre-reinforced composite materials. Although lightweight, the composite raw material can be expensive and the sequential component production challenging and costly. LÄS MER
