  1. 31. Investigation on the effect of pore size and surface area of mesoporous silica on the conductivity of solid composite electrolytes

    University essay from KTH/Tillämpad fysik

    Author : Hitesh Khanna Pedaprolu; [2022]
    Keywords : Solid Composite Electrolytes SCE ; Mesoporous Silica; Silica SiO2 ; Ionic Liquid Electrolyte ILE ; Fasta sammansatta elektrolyter SCE ; mesoporös kiseldioxid; kiseldioxid SiO2 ; jonisk flytande elektrolyt ILE ;

    Abstract : Solid-state batteries are gaining a lot of attention in the commecial sector today. Development of the solid state electrolytes is an important part in making commercially viable solid-state batteries. READ MORE

  3. 32. EVALUATION OF ENVIRONMENTAL AND TECHNICAL PERFORMANCE OF ALTERNATE FIBRES FOR SHOTCRETE IN TUNNELS

    University essay from KTH/Betongbyggnad

    Author : Shilpa Anand; [2022]
    Keywords : Shotcrete; Life cycle assessment; Environmental Product Declaration; Global warming potential; steel; basalt and synthetic fibres; flexural strength; energy absorption.;

    Abstract : Tunnels in hard and jointed rock are normally excavated in an arch shape to enable the rock mass to support its weight. Since the beginning of the 1980's, fibre reinforced shotcrete (FRS) in combination with rock bolts have been the dominating support method for hard rock tunnels. READ MORE

  4. 33. Analysis of Resin Impregnated Non-woven : In collaboration with Hitachi Energy

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Ahmed Abdulkareem Najm Al-Saedi; Anders Hedenfeldt; Andrea García; Anna-Karin Kron; Cornelia Bergström; Lova Källkvist; [2022]
    Keywords : resin impregnated non-woven; bushings; composite; resin impregnated paper; tensile; bending; permeability; mechanical properties;

    Abstract : High voltage bushings are the most critical components of power transformers. A common material used in bushings is resin impregnated paper (RIP). Hitachi Energy is investigating whether this can be replaced with a new material, resin impregnated non-woven (RIN). READ MORE

  5. 34. Adhesive bonding of fiber laminate patch to sandwich-structured composite

    University essay from Lunds universitet/Materialteknik

    Author : Daniel Nesic; [2022]
    Keywords : Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

    Abstract : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. READ MORE

  6. 35. Micro- / Meso- Scale Dielectric Strength Testing of Fibre Composites

    University essay from Umeå universitet/Institutionen för fysik

    Author : Johannes Fernberg; [2022]
    Keywords : Dielectric strength; composite; GFRP; glassfibre; composite microstructure; FEA; electric breakdown; single fibre;

    Abstract : Glass fibre composites are common materials used in high voltage applications as insulating materials that provide good structural integrity. The aim of this thesis is to develop a method of studying the failure in such materials by measuring the dielectric strength on micro- and meso- scale samples, consisting of single fibre filaments and fibre bundles respectively embedded in epoxy resin.
