  1. 16. Structural concrete elements subjected to air blast loading

    Författare :Johan Magnusson; Anders Ansell; Bengt Vretblad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Sammanfattning : In the design of structures to resist the effects of air blast loading or other severe dynamic loads it is vital to have large energy absorbing capabilities, and structural elements with large plastic deformation capacities are therefore desirable. Structures need to be designed for ductile response in order to prevent partial or total collapse due to locally failed elements. LÄS MER

  3. 17. Carbon-graphite fiber-reinforced polymers for implant suprastructures

    Författare :Susanna Segerström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Implant prostheses; Matrix; MMA; PMMA nanoparticles; Copolymer; Surface treatment; Size; Adhesion; SEM; Mechanical properties; Physicochemical properties.;

    Sammanfattning : Carbon-graphite fiber-reinforced polymers (CGFR) can be used as the core material for implant-retained prostheses as an alternative to metal frameworks. The purpose was to formulate and develop carbon-graphite fiber-reinforced polymers intended for implant suprastructures and to determine physicochemical, mechanical properties and possible cytotoxic effects.

  4. 18. Properties of Modern Rendering Systems based on Mineral Binders

    Författare :Carl-Magnus Capener; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymers; mortar; rendering; properties; microstructure; admixtures; chemistry;

    Sammanfattning : Composite mineral–organic materials and in particular cement-organic materials are increasingly used in today’s construction applications and civil engineering projects. Polymer-modified render is a material that possesses several properties superior to conventional renders, such as better workability, crack resistance, adhesion to substrate and flexural strength.

  5. 19. Resin transfer moulded composite materials : processing, structure, property relationships

    Författare :J. Anders Holmberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : This thesis contains analysis of the performance of polymer composites manufactured by resin transfer moulding (RTM). The thesis consists of six papers, where the first two deals with the tensile strength of composites reinforced with randomly oriented glass fibres, which still is the most common reinforcement in RTM manufacturing.

  7. 20. All-ceramic Fixed Partial Denture. Studies on aluminum oxide- and zirconium dioxide-based

    Författare :Per Vult von Steyern; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dental ceramics; dental porcelain; all-ceramic; fixed partial dentures;

    Sammanfattning : Keramiska material har länge använts inom tandvården för framställning av tandersättningar. Keramer har många goda egenskaper som gör dem särskilt lämpliga att använda i munnen. LÄS MER
