  1. 1. Graphene as Solid Lubricant in Polymer Composites : With Application in Hydropower Bearings

    Author : Julian Somberg; Nazanin Emami; Jan Ukonsaari; Gil Gonçalves; Sergei Glavatskih; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Solid Lubricant; Polymer Composite; Friction; Hydropower; Machine Elements; Maskinelement;

    Abstract : With a rising global demand for green energy production, hydropower plays a key role in securing a reliable and sustainable energy supply. Hydropower is the largest and most efficient renewable energy source, with an ever-increasing capacity. READ MORE

  2. 2. Tribology of polymer composites for elevated temperature applications

    Author : Jonna Lind; Åsa Kassman Rudolphi; Stefan Silverbåge; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tribology; polymer composite; friction; wear; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : Polymers as construction material are common in the industry. Although more recently the use of polymer composites in more demanding applications has increased, requiring more of them mechanically, tribologically and thermally. To enhance the properties various fillers are used, from common glass fibers to more advanced nanoparticles. READ MORE

  3. 3. Physically based constitutive models for crash of composites

    Author : Sergio Costa; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crushing; FEA; friction; damage mechanics; CDM; kinking;

    Abstract : The transportation industry and passenger cars in particular are strong emitters of gases that contribute to the climate crisis. For this reason, the automotive industry investigates opportunities to reduce emissions, such as reducing the weight of the car. READ MORE

  4. 4. Tribology of self-lubricating polymer composites for hydropower applications

    Author : Maria Rodiouchkina; Jens Hardell; Kim Berglund; Jan Ukonsaari; Michał Wasilczuk; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymer composites; hydropower; sliding wear; sliding friction; self-lubricating; transfer layers; material characterization; surface analysis; high contact pressure; low sliding speed; Machine Elements; Maskinelement;

    Abstract : The ongoing global climate crisis and its impacts calls for urgent actions, such as significant reduction of CO2 emissions by introducing more renewable energy. This has led to a rapid integration of variable power sources, such as wind and solar power, into the electricity systems. READ MORE

  5. 5. Physically based fibre kinking model for crash of composites

    Author : Sergio Costa; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kinking; Crushing; FEA; damage mechanics; friction;

    Abstract : Passenger cars are a major emitter of global warming gases which has led to tighter regulations being imposed on car manufacturers. An efficient way to reduce emissions is to reduce the weight of the cars. READ MORE
