  1. 1. A Feasibility Analysis of Natural Composite Alternatives in High Performance Sailing Vessels

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Sabrina Smith; [2023]
    Nyckelord :F50 catamaran; sustainable materials; marine applications; flax laminates; mechanical testing; environmental analysis; weight distribution; yacht performance;

    Sammanfattning : The construction of high-performance vessels like the F50 catamaran has traditionally prioritized advanced composite materials and performance-driven design. However, there is a growing need to incorporate sustainable materials and practices, with their performance in marine applications remaining relatively unknown. LÄS MER

  3. 2. Utvärdering av potentiell biomassa från Zambia för tillverkning av bränslepellets : Pelletsproduktion i enpetarpress, friktions- och kompressionsstudier samt hårdhetstest och fuktupptag

    Master-uppsats, Karlstads universitet

    Författare :Lisa Henriksson; [2018]
    Nyckelord :Biomass; single pellet press; moisture uptake; hardness; compression; friction; lignin; cellulose; hemicellulose; Zambia; Biomassa; enpetare; pellets; fuktupptag; hårdhet; kompression; friktion; lignin; cellulosa; hemicellulosa; Zambia;

    Sammanfattning : Biomass has been used as a fuel since ancient times. In recent decades the use has increased and the technology has developed considerably in large parts of the world. In Sub Saharan Africa, traditionally used biomass, such as wood or charcoal, is still the main source of energy in households. LÄS MER

  4. 3. Fuktsäkerhet inom nyproduktion : Väderskydd

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

    Författare :Narmin Kader; Kimia Khoshdel; [2018]
    Nyckelord :Fuktsäkerhet; nyproduktion; väderskydd; bygg; Wästbygg; prefabricerad element;

    Sammanfattning : This report is created in order to pay attention to moisture safety in new constructions with the help of weather protection systems. This is a new technique which has been introduced to the construction business, but it is a technique that has still not raised enough attention in the business. LÄS MER

  5. 4. Permeability in surface treated Norway spruce samples- Effect of wood properties

    M1-uppsats, Institutionen för teknik, TEK

    Författare :Josefin Nilsson; [2012]
    Nyckelord :Norway spruce; Picea abies; durability; water uptake; wood properties;

    Sammanfattning : In Norway spruce there's a large natural variation in durability but knowledge about what is causing this variation is missing. In this thesis the focus were put into investigating how the water uptake ability was affected by the influence of heartwood versus sapwood and wood properties such as density and annual ring width.
