  1. 1. Influence of Ageing on Material Properties at Interfaces in Composite Insulators

    Författare :Johan Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite insulators; ageing; silicone rubber; salt fog test; Outdoor insulation; inclined plane test; interfaces;

    Sammanfattning : High quality of internal interfaces in composite insulators for high voltage applications is necessary for securing durability of their functionality. Weak macroscopic interfaces between the glass fibre reinforced (FRP) epoxy core and the silicone rubber (SIR) housing, such as spots with reduced bonding or a loss of the adhesion as well as presence of foreign contaminants, can appear to have an accelerating effect on the evolution of ageing processes, though it may take years before the first signs of processes endangering the insulator function appear.

  3. 2. Development and Evaluation of Mechanical Joints for Composite Floor Elements with Cross Laminated Timber

    Författare :Nicolas Jacquier; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : One of the important issues in the development of a multi-storey timber construction system is the definition of the floor solution. This thesis focuses on the development of composite floor solutions where Cross Laminated Timber (CLT) panels are used as a base element. LÄS MER

  4. 3. Strong blast wave interaction with multiphase media

    Författare :Sembian Sundarapandian; Nicholas Apazidis; Konstantinos Kontis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast waves; negative pressure; cavitation; blast wave attenuation; RMI; KHI; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The interaction of a blast wave propagating in air with different fluids like water column, aqueous foam and thermal/density inhomogeneity have been studied both experimentally and numerically. The blast waves were generated at atmospheric conditions in a newly constructed exploding wire facility. LÄS MER

  5. 4. Properties and Long-Term Performance of Internal Interfaces in Composite Insulators

    Författare :Johan Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : An important component that secures durability of composite insulators for high voltage applications is the quality of internal interfaces. Weak interfaces, in form of a reduced bonding or a loss of the adhesion between the insulation components, can be devastating for the long-term functionality of an insulator. LÄS MER
