  1. 1. Multiscale Analysis of Multifunctional Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Ammara Dil; [2019]
    Keywords : ;

    Abstract : Conventional polymer composites are highly demanding due to their high strength and stiffness, low weight, easy processing and corrosion resistance. However, their weak out of plane properties restricts their use in high performance applications, such as aerospace, military and automotive components. READ MORE

  2. 2. Study on the impact of CNT or graphene reinforced interlaminar region in composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Tobias Karlsson; [2019]
    Keywords : Carbon fiber composite; electrical conductivity; electromagnetic interference shielding effectiveness; CNT; Buckypaper;

    Abstract : The interlaminar region is a contributing factor to the limited electrical conductivity of carbon fiber/epoxy composites. Consisting of electrically insulating epoxy matrix between conductive layers of carbon fiber, the interlaminar region prevents electrical interaction between the carbon fiber layers and electrical conduction in the through thickness direction.

  3. 3. A Preliminary Optimisation and Techno-economic Analysis of Solar Assisted Building Heating System Using Transpired Air Solar Collector and Heat Pump in Sweden

    University essay from Högskolan Dalarna/Energiteknik

    Author : Puneet Kumar Saini; [2019]
    Keywords : Solar energy; air heating; Optimisation; heat pump; transpired air collector;

    Abstract : This thesis presents an optimisation approach and techno-economic evaluation tool for a system consisting of a transpired solar air collector and air source heat pump in a series arrangement. The thesis also investigates the application of the developed tool for feasibility study of a solar heat pump system for a group of three multi-family houses located in Ludvika, Sweden. READ MORE

  4. 4. Green Roof Performance in Cold Climates : A study on how different plants suited for the subarctic climate in northernSweden affects the performances of green roofs

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jonathan Hjelm; [2019]
    Keywords : Stormwater; Green roofs; Cold climate; Stormwater management;

    Abstract : Increased urbanization leads to an increasing amount of impervious surfaces and a decrease ofthe natural hydrological function. Urban stormwater does thus risk to create high surface flows which could damage the receiving water bodies (e.g. erosion) or the urban area itself (flooding). READ MORE

  5. 5. Computational modeling strategy of steel connections

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Carl-Michael Bjälkensäter; Carl Holmgren; [2019]
    Keywords : FEM; steel; connection; joint; Technology and Engineering;

    Abstract : When designing large complex steel structures numerical calculation methods are always used to some extent. The simulation technology of today is advanced and can with proper modeling technique provide detailed analyses which captures the structural response accurately. READ MORE
