  1. 1. Flexible Composites - Strength, Deformation and Fracture Proecesses in Woven and D.O.S. Reinforcement Materials

    Författare :Torbjörn Dartman; Industriell Produktion; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kompositmaterial; Composite materials; Textile materials; Joints; Coated fabrics; Tear strength; Flexible composites; Damage resistance;

    Sammanfattning : In this thesis the tensile strength, deformation, damage resistance and tear propagation for flexible composites are analysed. There are two essential requirements common to all flexible composites; namely, high tearing strength and good matrix-to-fabric adhesion. The interaction of fabric and matrix is complex. LÄS MER

  3. 2. Lighting and Sensing Applications of Nanostructured ZnO, CuO and Their Composites

    Författare :Ahmed ELtahir Elsharif Zainelabdin; Magnus Willander; Omer Nour; Leonard J. Brillson; Linköpings universitet; []
    Nyckelord :ZnO; CuO; Nanostructures; Composites; ZnO polymer LEDs; humidity sensor; p-n heterojunction;

    Sammanfattning : Low dimensional nanostructures of zinc oxide (ZnO), cupric oxide (CuO), and their composite nanostructures possess remarkable physical and chemical properties. Fundamental understanding and manipulation of these unique properties are crucial for all potential applications. LÄS MER

  4. 3. Visualisation of composites manufacturing

    Författare :Magnus Andersson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The five papers in this thesis demonstrate five unique ways to monitor composite manufacturing. They also clarify several phenomena that take place during composite manufacturing. Of particular interest are two manufacturing methods, namely vacuum infusion (Paper A-D) and compression moulding of SMC (Paper E). LÄS MER

  5. 4. Solution-Processable Conductive Graphene-Based Materials for Flexible Electronics

    Författare :Jie Zhao; Zhi-Bin Zhang; Shi-Li Zhang; Matti Mäntysalo; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Graphene oxide; Silver; Copper; Composite; Conductive inks; Flexible electronics; Printed electronics; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

    Sammanfattning : This thesis work explores electrical conductors based on few-layer graphene flakes as an enabler for low-cost, mechanically flexible, and high-conductivity conductors in large area flexible and printed electronic devices. The flakes are deposited from aqueous solutions and processed at low temperature. LÄS MER

  7. 5. Vacuum infusion of polymer composites

    Författare :Magnus Andersson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : The current trend towards an increased use of vacuum infusion for manufacturing of high performance fibre reinforced polymer composites has stressed the necessity of an advanced modelling of the process. Until recent years development in this area has mainly been based on trial and error and the behaviour of the method is therefore not fully understood. LÄS MER
