  1. 16. Evaluation of a computational method for natural fiber-reinforced plastics

    University essay from KTH/Hållfasthetslära

    Author : Anna Lim; [2023]
    Keywords : PPNF; Composite material; fiber orientation; natural fiber; coupled analysis; PPNF; Kompositmaterial; fiberorientering; naturfiber; kopplad analys;

    Abstract : The importance of using natural fiber composites (NFCs) has been addressed as a substitution for synthetic fibers, such as glass and carbon fibers. This substitution contributes significantly to reducing greenhouse gas emissions, aligning with the environmental responsibilities of engineering industries. READ MORE

  3. 17. Combustibility study of resin for warm magnet coils used at CERN

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Juan Carlos Lopez Santiago; [2023]
    Keywords : Epoxy resin; flammability; radiation; aging; cone calorimeter; micro combustion calorimeter; thermogravimetric analysis; lateral ignition and flame spread test; chemical composition of polymers; polymers; epoxy composite; polymer composite; failure of epoxy resins; magnetic coil; Technology and Engineering;

    Abstract : CERN is the world's largest particle physics laboratory, housing multiple accelerators that rely heavily on magnetic coils. These coils are integral to the generation of powerful magnetic fields essential for particle accelerator experiments, detectors, and other equipment. READ MORE

  4. 18. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  5. 19. Transmission expansion planning considering Probabilistic Risk Assessment : Implemented at Swedish National Grid

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jakob Björns; [2023]
    Keywords : Probabilistic risk assessment; PSS E; Transmission expansion planning; National grid; Probabilistisk riskbedömning; PSS E; Transmissionsnätsutveckling; Stamnät;

    Abstract : Svenska kraftnät (Swedish National Grid) is the transmission system operator in Sweden and is responsible for maintaining and developing the Swedish transmission grid. One of the tasks included in this responsibility is transmission expansion planning, which means analyzing and planning the capacity in the future transmission grid for the requested load and generation.

  6. 20. Evaluation of Woodmer/plastic composites

    University essay from KTH/Fiber- och polymerteknologi

    Author : Leon Ahlström; [2023]
    Keywords : Extrusion; Woodmer; Flame test; Tensile test; Composites; Extrudering; Woodmer; Flamtest; Dragtest; Kompositer;

    Abstract : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. READ MORE
