  1. 6. 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

  2. 7. Analysis of Stiffness Measurement Methods on Extracellular Vesicles

    University essay from KTH/Tillämpad fysik

    Author : Hanna Kylhammar; [2022]
    Keywords : Extracellular Vesicles; AFM; Atomic Force Microscopy; Fluorescent Microscopy; Extracellulära Vesiklar; AFM; Atomkraftsmikroskopi; Fluorescensmikroskopi;

    Abstract : Extracellular vesicles are important players in cell-to-cell communication and have the potential to be used as biomarkers for decease. The mechanical properties of extracellular vesicles is an active field of research, with new methods and models being developed. READ MORE

  3. 8. Enhancing the endurance of UAVs by the use of structural power composites: System-level study of a flying wing

    University essay from KTH/Lättkonstruktioner

    Author : Gustav Burman; [2021]
    Keywords : ;

    Abstract : This thesis studies the feasibility of integrating the novelStructural Battery (SB)[1] into the airframe of a UnmannedAerial Vehicle (UAV). The potential advantages in terms ofmass, range and endurance are studied.The aircraft performance is analysed using conventionalflight mechanics, modelled in Matlab and Xfoil. READ MORE

  4. 9. Dynamic Design of Bridges on High-Speed Railway Lines

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Felicia Nilsson; Filippa Dahl; [2019]
    Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

    Abstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE

  5. 10. 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.
