  1. 1. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Sofia Westberg; [2023]
    Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

    Abstract : 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. READ MORE

  3. 2. Risk assessment of non-intentionally added substances in polyester yarn made from recycled polyethylene terephthalate (PET)

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristina Arnqvist; [2023]
    Keywords : r-PET; polyester yarn; NIAS; risk assessment;

    Abstract : Polyester is a synthetic material made from polyethylene terephthalate (PET), which is synthesised from fossil raw materials. Many clothing manufacturers are using polyester in their clothing, which, from an environmental perspective, creates a non-sustainable cycle. READ MORE

  4. 3. Continuous Fibre Reinforcements in Injection Moulded Composites

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Erik Björkqvist; [2023]
    Keywords : Injection moulding; Plastics; Thermoplastics; Fibre Reinforcement; FEM; Formsprutning; Plast; Termoplast; Fiberarmering; FEM;

    Abstract : The use of continuously reinforced thermoplastics have increased in recent years andoffer some significant advantages over their thermoset counterparts. The utilizationof these materials is however still limited due to the labour intensive processingand manufacturing. READ MORE

  5. 4. Multiple Fibre Bragg Grating Force Sensor

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Felix Fritzén; [2023]
    Keywords : FBG force sensor; Fiber Bragg Grating force sensing; Fiber optic force sensor; Optical force sensing; Strain-based force sensing; Bragg wavelength shift; Force measurement using FBG; Fiber optic sensing technology; Fiber optic grating sensor;

    Abstract : The purpose of this project is to explore the FBG (Fiber Bragg Grating) technology and create a force sensor. The result can be used as a basis for further projects.The project starts with force and strain measurements. The project then evolves to incorporate multiple FBG sensors. READ MORE

  6. 5. Exploring Particulate Filtration during Thermal Runaway in Lithium-Ion Battery Packs

    University essay from KTH/Kemiteknik

    Author : Amanda Halvarsson; [2023]
    Keywords : battery pack; particles; thermal runaway; filtration; batteripack; partiklar; termisk rusning; filtrering;

    Abstract : Med övergången till elektrifiering inom transport uppstår nya utmaningar när det gäller batterisystem som placeras i elfordon. Det finns för närvarande en möjlighet att minska riskerna med toxiciteten hos partiklar som sprutas ut med de gaser som bildas under termisk rusning i litiumjonbattericeller som är placerade i batterisystem.
