  1. 1. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

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

    Författare :William Tönnberg; [2022]
    Nyckelord :Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Sammanfattning : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. LÄS MER

  3. 2. Mechanical properties of compression moulded fibre composite sheets

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Jakob Engström; [2021]
    Nyckelord :;

    Sammanfattning : This master thesis project was carried out at a large international company in the forest industry. The company is currently interested in producing sheet formed composite materials with high wood fibre content that can be further processed and formed using conventional compression moulding.

  4. 3. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing

    Master-uppsats, KTH/Materialvetenskap

    Författare :Julia Sjöström; [2020]
    Nyckelord :Maraging steel; selective laser melting; temperature evolution; macro-scale modelling; segregation; ICME.;

    Sammanfattning : Additive manufacturing methods for steel are competing against commercial production in an increasing pace. The geometry freedom together with the high strength and toughness due to extreme cooling rates make this method viable to use for high-performance components. The desirable material properties originate from the ultrafine grain structures. LÄS MER

  7. 5. Macro segregation in continuous cast HSLA steels : With correlation to impact toughness

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :August Åström; Morgan Sten; [2019]
    Nyckelord :Macro segregation continuous cast HSLA steels correlation impact toughness strength statistical analysis;

    Sammanfattning : The report reviews macro segregations in continuous cast steels and possible correlations to impact toughness. The purpose of the thesis is to investigate centreline segregates and V-segregates to see which of them that affect impact toughness the most. LÄS MER
