  1. 1. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.

    University essay from Lunds universitet/Industriell Produktion

    Author : Cornelis Botermans; [2023]
    Keywords : Technology and Engineering;

    Abstract : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. READ MORE

  3. 2. 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

  4. 3. Production of biocomposite materials from filamentous fungi grown on apple pomace

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Angela Sabbagh; Susanna Bahari; [2022]
    Keywords : ;

    Abstract : Managing and reducing food waste has increasingly become a global problem in later years, including food waste in the form of fruit pulp from the juice and beverage production industries. Another current urgent issue is the need for a replacement of fossil fuel-based plastics with more sustainable biopolymers. READ MORE

  5. 4. Effects of Temperature and Moisture Content on Young’s Modulus in Glass Fiber Reinforced Polyamide

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Joel Sandberg; Samuel Sjölin; [2022]
    Keywords : Polyamide; nylon 66; PA66GF25; glassfiber reinforced polyamide; Young’s modulus; Polyamid; nylon 66; PA66GF25; glasfiberförstärkt polyamid; Youngs modul.;

    Abstract : This thesis was made in cooperation with Roxtec. Roxtec specialises in cable sealingsolutions and are world leading in their area. In many of Roxtec’s products steel isused in the frame holding the sealing rubber. To lower Roxtec’s environmental foot-print plastic would be used instead in the frames if possible, more specific polyamide6. READ MORE

  6. 5. Enhancement of translucence in fiber-based packaging materials

    University essay from KTH/Fiber- och polymerteknologi

    Author : Saila Tallinen; [2022]
    Keywords : Paper; translucent; fiber-based packages; impregnation; cellulose; papper; genomskinlighet; fiberbaserade förpackningsmaterial; impregnering; cellulosa;

    Abstract : The utilization of fiber-based packages has started to take more place at the packaging sector but is still restricted by a lack of transparency. Today this challenge is tried to be solved by paying more attention on the characteristics of nanofibers and their possibilities. READ MORE
