  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

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Characterization of a Novel Tubular Carbon Fibre Based Electrode for Dopamine Detection with Fast Scan Cyclic Voltammetry

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

    Author : Sofia Hansson; [2022]
    Keywords : FSCV; Carbon Fibre Microelectrodes; Electrode development; Dopamine; Parkinson’s disease; In-vitro; FSCV; Kolfibermikroelektroder; Elektrodutveckling; Dopamin; Parkinsons sjukdom; In-vitro;

    Abstract : Fast Scan Cyclic Voltammetry (FSCV) is an electrochemical technique, based on ramping a voltage through a microelectrode and measuring the resulting redox current to obtain information about an electroactive molecule. FSCV can be used for the detection of dopamine, which is a vital neurotransmitter. READ MORE

  4. 3. Energy Efficient Composites for Automotive Industry.

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Abstract : 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. READ MORE

  5. 4. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Mercedes Amelia Bettelli; [2020]
    Keywords : Carbon Fibres Reinforced Polymer Composite; epoxy resins; cure behaviour; residual stress and shape distortions;

    Abstract : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. READ MORE

  6. 5. Design of Ultra High Performance Fibre Reinforced Concrete Bridges : A Comparative Study to Conventional Concrete Bridges

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Viktor Eriksson; [2019]
    Keywords : Bridge design; CO2 emissions; Mechanical properties and behaviour; Straight short steel fibres; UHPC; UHPFRC; Bro dimensionering; CO2 utsläpp; Korta raka stålfibrer; Mekaniska egenskaper och beteende; UHPC; UHPFRC;

    Abstract : The use of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) in the construction industry started in the 1990s and has since then been used for bridges all over the world. The mechanical properties and the dense matrix result in lower material usage and superior durability compared to conventional concrete, but the implementation of UHPFRC in the Swedish industry has been delayed.
