  1. 1. Thermoset biopolymer reinforced with carbon-nanotubes

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Morteza Esmaeili; [2019]
    Nyckelord :biopolymers; bio-composites; glycerol lactic acid; carbon nanotube; reinforcement; thermoset; dispersion;

    Sammanfattning : Compared to conventional fibers, carbon nanotubes possess several significant properties, which make them as an excellent alternative reinforcement in multi-functional material industry. In this study, the possibility of dispersion of the multi-wall carbon nanotube (MWCNTs) in a thermoset bio-based resin (synthesized based on end-functionalized glycerol-lactic acid oligomers, GLA, at university of Borås) was investigated.

    Sammanfattning : Aluminium is one of the metals playing a prominent role in automobile industry after cast iron. Because of its light weight property and good mechanical properties. When aluminium reinforced with silicon carbide showing good tribological properties and improved strength. LÄS MER

  4. 3. Influence of ANS Triboconditioning on friction and fatigue in rolling contact configurations

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Björn Hedmark; Per Wallgren; [2019]
    Nyckelord :Tribology; friction; fatigue; micropitting; surface engineering; twin-disc; triboconditioning; LTU;

    Sammanfattning : The automotive industry is constantly being challenged by customers and authorities to enhance the efficiency of the internal combustion engine (ICE) in order to achieve improved fuel consumption and reduced emissions. There are several interfaces within the design of an ICE that causes frictional losses, one of them is the valvetrain. LÄS MER

  5. 4. Mechanical and Thermal Characterisation of Novel UHMWPE Composites for Total Joint Arthroplasty

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

    Författare :Julian Somberg; [2019]
    Nyckelord :UHMWPE; Nanocomposites; DSC; Fracture Toughness; Wear;

    Sammanfattning : Total joint arthroplasty surgeries are known to have a high success rate but the longevity of the implants still acts as a limiting factor. Ultrahigh molecular weight polyethylene is the material of choice for the implant bearing surfaces due to its excellent clinical and tribological performance. LÄS MER

  7. 5. Enhancement of Phenol Formaldehyde Adhesive with Crystalline Nano Cellulose

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Författare :Johan Ekstrand; [2019]
    Nyckelord :Nano Cellulose; Fibrillated cellulose; Wood Adhesive; Shear strength; Adhesive Enhancement; Formaldehyde adhesive; Phenol Formaldehyde;

    Sammanfattning : Abstract The wood industries to this day use almost exclusively petroleum derived adhesives that are based mainly on the reaction of formaldehyde with urea, melamine or phenol. These adhesives have low cost and good adjustable properties which makes it hard for bio-based alternatives to compete. LÄS MER
