  1. 1. Incorporating Flax Fiber Composites in Hypercar Panels

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Hanna Öster; Sara Isorena Guðjónsdóttir; [2023]
    Nyckelord :sound transmission loss; coincidence frequency; sound pressure level; flax fibre; carbon fibre; ljudtransmission; koincidensfrekvens; ljudtrycksnivå; linfiber; kolfiber;

    Sammanfattning : This thesis investigates sound transmission loss through flat finite panels using composite materials, which incorporate both carbon and flax fibres. The study wascarried out by performing FEM simulations developed and validated in steps. Thevalidation process was time-consuming but crucial in ensuring the model’s reliability. LÄS MER

  3. 2. Energy Efficient Composites for Automotive Industry.

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Mariana Rojas; [2021]
    Nyckelord :Hybrid composites; Short fibres; Carbon fibres; Flax fibres; Manufacturing; Resin Transfer Moulding RTM ; Vacuum infusion; Tensile tests; Flexural tests;

    Sammanfattning : Hybrid composites play a key role in sustainable development. For many years, carbon fibres in an epoxy matrix have been an attractive option for many structural applications because of their higher specific mechanical properties mostly. LÄS MER

  4. 3. The applicability of agricultural fibres in industrial cleaning cloths : in the aspects of processability and sustainability

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Liv Walker; Karin Essén; [2020]
    Nyckelord :Nonwoven; Industrial cleaning cloth; Agricultural fibres; Bast fibres; Polyester; Single-use; Nonwoven; Industriella rengöringsdukar; Naturliga fibrer; Bastfibrer; Polyester; Engångsartiklar;

    Sammanfattning : This study has its background in the EU directive, the ‘Single-Use Plastics Directive’. The directive was initiated due to the environmental impacts that the oceans suffer due to plastic waste. The directive presents the most common single-use products found as waste in the oceans, including wipes and cloths. LÄS MER

  5. 4. Environmental Impact Analysis of Flax Fibre Cultivation for Composite Reinforcement

    Magister-uppsats, Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Författare :Elin Jacobsson; [2018]
    Nyckelord :flax fibre; life cycle assessment; reinforcement; environmental impact assessment;

    Sammanfattning : Searching for environmentally sustainable alternatives for reinforcement of composite materials, flax fibre has one of the most promising potentials due to its desired mechanical properties. The fact that flax is a bio-material, in contrast to conventional synthetic fibres, does not ensure a less environmental impact. LÄS MER

  7. 5. Norges första oljeexploatering? : En arkeobotanisk och morfometrisk undersökning av linfrön från Eikebakken, Norge

    Kandidat-uppsats, Umeå universitet/Institutionen för idé- och samhällsstudier

    Författare :Ida Lundberg; [2017]
    Nyckelord :Arkeobotanik; Chenopodium; Linum usitatissimum; lin; Norge; Rogalands fylke; sen bronsålder; tidig järnålder; experimentell arkeologi; Morfometrisk undersökning;

    Sammanfattning : This bachelor’s thesis is based on the charred archaeobotanical material from a settlement at Eikebakken, Norway dated to the end of Bronze Age. The study focuses on determining the potential use of weeds and the oil plant flax (Linum usitatissimum). LÄS MER
