    Sammanfattning : Nowadays, the forestry industry still uses heavy machinery damaging both the forest and the soil. The start-up AirForestry is currently developing a sustainable way to thin and harvest trees. With their 6.2m wide electric drone carrying a harvesting tool, they can reach, thin, cut and carry trees without the need for access roads. LÄS MER

  3. 2. Embedding Carbon Nanotubes Sensors into Carbon Fiber Laminates

    Master-uppsats, KTH/Materialvetenskap

    Författare :Riccardo Andolfi; [2022]

    Sammanfattning : The use of Fibre Reinforced Polymer (FRP) composite materials in structural applications has increased in the past decades in high­performance sectors, such as in the automotive and aeronautic industries, for weight reduction purposes. However, FRP composite materials can offer more significant innovation potential. LÄS MER

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

    Master-uppsats, KTH/Lättkonstruktioner

    Författare :Gustav Burman; [2021]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  5. 4. 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

  7. 5. Virtual characterization of composite materials for aero-engine components

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

    Författare :Facundo Masari; [2020]
    Nyckelord :Composite; simulation; multiscale; modelling; UD; NCF; prepreg; aerospace; engine;

    Sammanfattning : Since its beginnings, the aerospace industry has been interested in lowering the weight of aircraft. Moving from performance and economic drivers to environmental design parameters, the weight has continuously been a major focus for this industry. LÄS MER
