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

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Sammanfattning : 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. 2. Additive Manufacturing - Integration of Functions in EMI-shields

    Master-uppsats, KTH/Hållfasthetslära (Inst.)

    Författare :Alexandra Lidholm; [2019]
    Nyckelord :;

    Sammanfattning : Additive manufacturing enables a simplified production process of components with complex geometry based on computer aided three-dimensional design. The technology of creating components layer-by-layer allows an efficient process with the ability to design parts with specific properties which can be difficult to obtain when conventional manufacturing methods are used.

  4. 3. Power cables in battery electric vehicles used in underground mining : Analysis of electromagnetic dynamics in high-power cables and development of application-specific design strategies for reduction of EMI

    Master-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Chisom Miriam Ekweoba; [2019]
    Nyckelord :;

    Sammanfattning : The electrification of the automotive industry is growing in popularity, considering the environmental impacts of the conventional diesel-powered automobile. However, from the electromagnetic compatibility (EMC) viewpoint, it is observed that the use of variable-frequency drives (VFD) and relatively high-power cables to propel electrical motors has led to a considerable rise in electromagnetic interference (EMI) within and outside the machine.
