  1. 1. On the Fracture of Thin Laminates

    Författare :Sharon Kao-Walter; Blekinge Institute of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; interface; crack; adhesion; crack tip driving force;

    Sammanfattning : This thesis concerns mechanical and fracture properties of a thin aluminium foil and polymer laminate that is widely used as packaging material. The possibility of controlling the path of the growing crack propagation by adjustment of the adhesion level and the property of the polymer layer is investigated. LÄS MER

  3. 2. Analysis of geometrically modified adhesive joints in steel beams strengthened with composite laminates

    Författare :Reza Haghani Dogaheh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FE analysis; Stress concentration; Fillet; Laminate; Reverse tapering; Normal tapering; Adhesive joint; FRP;

    Sammanfattning : The use of bonded FRP laminates to strengthen and upgrade existing structures has attracted a great deal of attention during the past two decades. The attractiveness of this method is mainly due to the superior material properties of FRP laminates such as high strength and stiffness, as well as advantages associated with the bonding technique, such as ease of application and good fatigue performance.

  4. 3. Joining of Carbon Fibre Reinforced Plastics for Automotive Applications

    Författare :Gordon Kelly; KTH; []
    Nyckelord :Composite; laminate; bearing strength; joining; load introduction; hybrid joint; finite element analysis; mechanical testing;

    Sammanfattning : The introduction of carbon-fibre reinforced plastics in loadbearing automotive structures provides a great potential toreduce vehicle weight and fuel consumption. To enable themanufacture and assembly of composite structural parts,reliable and cost-effective joining technologies must bedeveloped. LÄS MER

  5. 4. Micro-cracking and delaminations of composite laminates under tensile quasi-static and cyclic loading

    Författare :Hiba Ben Kahla; Janis Varna; Zoubir Ayadi; Federica Daghla; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laminate; Fatigue; damage growth; stiffness reduction; NCF; Polymeric Composite Materials; Polymera kompositmaterial;

    Sammanfattning : Aerospace industry is devoted to improving the aircraft performance while reducing its weight and limiting the emissions. Part of this objective can be accomplished with the use of high-performance long fibre reinforced polymer laminated composites. LÄS MER

  7. 5. Protein-based Packaging Films, Sheets and Composites: Process Development and Functional Properties

    Författare :Sung-Woo Cho; Mikael Hedenqvist; Amar K. Mohanty; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; wheat gluten; solution casting; compression molding; extrusion; injection molding; aging; migration; opacity; heat sealability; hemp fiber; laminate; polylactic acid; clay; nanocomposites.; Other chemical engineering; Övrig kemiteknik;

    Sammanfattning : The depletion of the petroleum resources and a number of environmental concerns led to considerable research efforts in the field of biodegradable materials over the last few decades. Of the diverse range of biopolymers, wheat gluten (WG) stands out as an alternative to synthetic plastics in packaging applications due to its attractive combination of flexibility and strength, high gas barrier properties under low humidity conditions and renewability.
