  2. 21. Plate bonding : strengthening of existing concrete structures with epoxy bonded plates of steel or fibre reinforced plastics

    Author : Björn Täljsten; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : This thesis deals with several aspects of the plate bonding problem, i.e. when steel or fibre reinforced plastics (FRP) plates are bonded to a concrete structure with the use of an epoxy adhesive. Both theoretical work and laboratory tests are presented as well as a full scale test on a strengthened concrete bridge. READ MORE

  4. 22. Bio-based materials from crambe and carinata industrial oilseed meals : compression moulded and extruded oilseed meal plastics

    Author : William Newson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Protein-based plastics are considered as a new route for valorisation of oilseed meal from the industrial oil crops Crambe abyssinia (crambe) and Brassica carinata (carinata) as they cannot be used for animal feed or human food. To convert oilseed meals into protein-based plastic films compression moulding was used with varying processing temperature, chemical additives and protein extraction conditions. READ MORE

  5. 23. On the multifunctional performance of structural batteries

    Author : David Carlstedt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modelling; Multifunctional composites; Electrical properties; Carbon fibre reinforced plastics; Mechanical properties; Energy storage;

    Abstract : The structural battery composite is a composite material that can store electrical energy (i.e. work as a battery) while simultaneously provide mechanical integrity in a structural system. Due to its inherent ability to store energy this material offers significant weight savings on a system level. READ MORE

  6. 24. Transport Properties and Durability of LCP and FRP materials for process equipment

    Author : Stefanie Römhild; Mikael Hedenqvist; Rodney Rychwalski; KTH; []
    Keywords : Liquid crystalline polymer LCP ; Vectra A950; disclination; annealing; transport properties; diffusion; lining; bonding; glass fibre reinforced plastics FRP ; thermoset; vinyl ester; novolac; water; water activity; sorption isotherm; long-term properties; FEP;

    Abstract : This thesis focuses on transport properties and durability of liquid crystalline polymers (LCP)and fibre reinforced plastics (FRP) with regard to application in industrial process equipment.In the first part of the study the possibility of using a thermotropic LCP of type Vectra A950as lining material for FRP process equipment was investigated.
