  1. 1. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Amirhossein Gholami; Ali Abedisamarin; [2024]
    Nyckelord :Ageing. AA6014. AA6016;

    Sammanfattning : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.

  3. 2. Sustainable food packaging based on polyhydroxyalkanoate

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

    Författare :Safana Al-Ashor; [2024]
    Nyckelord :Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Sammanfattning : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. LÄS MER

  4. 3. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

    Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Karin Hindborg; [2023-08-28]
    Nyckelord :colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

    Sammanfattning : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.

  5. 4. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella material

    Författare :Sofia Westberg; [2023]
    Nyckelord :Carbon fiber; lignin; cellulose; continuous conversion;

    Sammanfattning : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. LÄS MER

  7. 5. Utdragshållfasthet och styvhet i axiellt belastade skruvinfästningar i korslaminerat trä

    Kandidat-uppsats, Jönköping University/JTH, Byggnadsteknik och belysningsvetenskap

    Författare :Carl Hagvall; Svante Wallin; [2023]
    Nyckelord :KL-trä; skruvförband; skruvinfästningar; styvhet; utdragshållfasthet; utdragsprov;

    Sammanfattning : Introduction – Cross-laminated timber (CLT) is a product that is becoming increasingly common in the construction industry. CLT is categorized as homogeneous or combined, where homogeneous has the same strength classes throughout the entire cross-section and combined has varying strength classes across the cross-section.
