  1. 6. A µCT Investigation of the Electrical Breakdown Mechanisms in Mica/Epoxy Machine Insulation

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Carl Saxén; [2017]
    Keywords : Breakdown; composite; computed tomography; epoxy; mica; resin; winding; x-ray; μCT;

    Abstract : Mica/Epoxy machine insulation is a composite material of the mineral mica, fibre-glass mesh and epoxy resin. The material is used in motors and generators rated for high voltage, where the material must withstand multiple stresses such as elevated temperatures, mechanical and electrical stresses. READ MORE

  3. 7. Master thesis within light warhead for support weapon : Investigation of defects, methods and requirement specifications in order to get a shell body shatter free

    University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

    Author : Adam Jansson; [2016]
    Keywords : warhead; support weapon; shell body; shatter free; defect; method; carbon fibre; epoxy; crack; delamination; porosity; CFRP; CFRE; NDT; verkansdel; understödsvapen; granathylsa; splitterfri; defekt; metod; kolfiber; epoxi; spricka; delaminering; porositet; OFP;

    Abstract : At launching the shell body, especially the backplane of the shell body, will be exposed to very high stresses due to acceleration, pressure and increased temperature from the propellant combustion. Defects in the shell body could in worst case for example result in high temperature gas leakage into the warhead and thereby ignite the explosives before exiting the launcher. READ MORE

  4. 8. Polymerization of Zwitterionic Sulphobetaine Methacrylate and Modification of Contact Lens Substrate

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Tobias Ingverud; [2015]
    Keywords : Zwitterionic; Sulphobetaine; RAFT; ATRP; End-group-modification; Grafting-to; Contact lens; zwitterjonisk; RAFT; ATRP; ändgrupps modifiering; ympning-till; kontakt;

    Abstract : In this study, the zwitterionic monomer [2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) was polymerized in a controlled manner by reversible addition-fragmentation chain transfer (RAFT) polymerization. The SBMA was also polymerized by atom transfer radical polymerization (ATRP) but in a less controlled manner why ATRP was discarded for further use in the study. READ MORE

  5. 9. CFRP strengthening of existing building structures

    University essay from Institutionen för teknik och naturvetenskap; Tekniska högskolan

    Author : Marlene Karlsson; [2007]
    Keywords : ;

    Abstract : Most of the building structures needed in twenty years from now is already built. Building structures are ageing and they deteriorate and often the demands on the structure changes over time. It is often needed to reinforce the structure, especially when reconstructing, repairing or renovating a building. READ MORE
