  1. 1. Adhesive bonding of fiber laminate patch to sandwich-structured composite

    University essay from Lunds universitet/Materialteknik

    Author : Daniel Nesic; [2022]
    Keywords : Adhesive bonding; Shipbuilding; Composite construction; Finite element method in structural mechanics; Fiber reinforced plastics; Optical microscopy analysis; Fractography; Technology and Engineering;

    Abstract : By using composites when constructing vehicles, lighter weight and thus better performance can be achieved. Composites are widely used in airplanes and small boats, but has yet to be incorporated in larger ships such as freighters and cruise ships. The main hindrance for its use is the lack of practical knowledge and experience. READ MORE

  3. 2. Towards sustainable shipping: Recommendations for the telescopic mast design of a sailing cargo vessel

    University essay from KTH/Lättkonstruktioner

    Author : Lukas Blau; [2021]
    Keywords : Oceanbird; telescopic mast; conceptual design; sailing cargo vessel;

    Abstract : A comparative study is carried out to investigate the most promising route towardsthe lightweight construction of a retractable mast for a sailing cargo vessel.Four design families are developed and compared. The primary criteria forjudgment are the structural mass, strength, and stiffness in relation to a providedbenchmark design. READ MORE

  4. 3. Investigation and implementation of rapid prototyping in development of a high-speed light craft

    University essay from KTH/Marina system

    Author : Ulrik Sköldkvist; [2021]
    Keywords : ;

    Abstract : Designing and constructing boats or ships is a slow, iterative process where the design goes through several steps in each iteration, and every loop in the process leads closer to the result. However, to verify if the boat's design functions, it must be built if there is no possibility to design, build, and evaluate smaller prototypes during the development. READ MORE

  5. 4. Development and verificationof a method to determine theshear properties of Hybrix core

    University essay from KTH/Lättkonstruktioner

    Author : Sangharsh Bhustalimath; [2020]
    Keywords : Fiber Core Sandwich Sheets; FCSS; Sandwich Construction; Digital Image Correlation; Three point bending test; Hybrix; Sandwichmaterial; fiberkärna; Digital bildkorrelation; Trepunkts; Hybrix;

    Abstract : This thesis helps develop a material model for a novel Fiber Core SandwichSheet construction. A test method was used to determine the mechanicalproperties of the sandwich material. Standard three point bendingtests coupled with digital image correlation was used. Results wereextracted from the digital image data. READ MORE

  6. 5. Temperature distribution in air tight cavities of steel framed modular buildings when exposed to fire

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Elin Bergroth; Greta Torstensson; [2019]
    Keywords : Cavities; fire furnace; fire test; modular building; steel; TASEF; Brandugn; brandtest; hålrum; modulbyggnader; stål; TASEF;

    Abstract : A common way to construct large buildings is by assemble prefabricated modules around a load bearing steel construction. However, if a fire occurs these buildings can be subject to a rapid fire spread due to its cellular nature. READ MORE
