  1. 1. Identification of Fibers in Micro-CT Images of Paperboard Using Deep Learning

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :David Rydgård; [2023]
    Nyckelord :Fiber networks; Paperboard mechanics; Deep learning; Tomography; Image analysis; Technology and Engineering;

    Sammanfattning : This master thesis project explores the possibility of using deep learning to segment individual fibers in three-dimensional tomography images of paperboard fiber networks. We test a method which has previously been used to segment fibers in images of glass fiber reinforced polymers. LÄS MER

  3. 2. Structural strengthening and sustainability improvements of existing buildings – A case study

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Pardis Niknafs; [2022]
    Nyckelord :Building retrofit; structural strengthening; energy efficiency; environmental impact; integrated and sustainable intervention; cross-laminated timber; life cycle assessment;

    Sammanfattning : In Sweden, a large share of residential buildings was built more than 50 years ago. Consequently, old materials, poor maintenance, and corrosion can affect the structural performance of these buildings. Additionally, these buildings do not meet the latest energy efficiency and Eurocode regulations. LÄS MER

  4. 3. Characterization of Fiber Orientation and Weld Line Effects in Reinforced Plastics with Reduced CO2eq Emissions

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Anders Tolf; Markus Johannesson; [2022]
    Nyckelord :Fiber-reinforced plastics; GFRP; Reduced carbon dioxide equivalent materials; Experimental; Uniaxial tensile test; Uniform fiber orientation plate; Tensile strength; Fiber orientation; Weld line; Fracture analysis; Microscopy;

    Sammanfattning : With increasing emphasis and regulations on the environmental footprint in industries, the integration of reduced carbon dioxide equivalent (CO2eq) plastic materials is desirable. Fiber-reinforced plastic materials mechanical properties differ with varying fiber orientations. LÄS MER

  5. 4. Mineral wool : From landfill to a sustaianble polymer composite

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Noéll Sjöbeck; [2022]
    Nyckelord :recycling; sustainability; waste management; circular economy; mineral wool; construction and demolition industry; composites; polymers; återvinning; hållbarhet; avfallshantering; cirkulär ekonomi; mineralull; bygg- och rivningsindustri; kompositer; polymerer;

    Sammanfattning : The focus of the project is recycling of the insulation material mineral wool. The aim is to investigate the potential of using post-consumer wool from landfill as fiber reinforcement in a polymer matrix. LÄS MER

  7. 5. Evaluation of alternative, sustainable polymer materials in regard to mechanical properties and sustainability

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Hanna Axelsson; Joaquin Rudervall; [2021]
    Nyckelord :sustainability; polymers; LCA; mechanical properties; testing; biobased; plastic; recycled; polymer technology; Technology and Engineering;

    Sammanfattning : We live in a world where products are consumed at an ever increasing rate, and where responsibility for the waste created is seldom taken. Plastics are in many ways wondrous materials, but they put a big strain on the environment, both in production and as waste. LÄS MER
