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

   Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

   Sammanfattning : 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. LÄS MER

4. 3. Konstruktion av fackverk och drivlina i ett navlöst hjul : Designprocess med jämförelse av metoder

   Kandidat-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik

   Författare :Elsa Ottosson; [2021]
   Nyckelord :Construction; innovation; bicycle wheel; sustainable environment; material selection; mechanics; product design; prototyping; Konstruktion; innovation; cykelhjul; hållbar miljö; materialval; mekanik; produktdesign; prototypframtagning;

   Sammanfattning : This paper is a part of the course PPU305 at Mälardalen University, the bachelor thesis. A companycurrently developing an electric bicycle had a concept of an innovative wheel containing no spokesand no hub. This meant that the functions these components usually fill needed to be solved in anotherway. LÄS MER

5. 4. Energy Efficient Composites for Automotive Industry.

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Sammanfattning : 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. LÄS MER

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

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

   Sammanfattning : 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. LÄS MER
