  1. 1. Solder Matrix Fiber Composite Thermal Interface Materials

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Josef Hansson; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal management; composite materials; solder; thermal interface material;

    Abstract : Overheating has been a problem for microelectronics devices for decades, and the problem is exacerbated by the continued trend of miniaturization of features and the corresponding increase in power density. Thermal interface materials (TIMs) target one of the main bottlenecks in heat transfer: the interface between two materials, such as between a heat-generating microchip and a heatsink. READ MORE

    Abstract : Low-density polyethylene (LDPE) nanocomposites containing metal oxide nanoparticles are considered as promising candidates for insulating materials in future high-voltage direct-current (HVDC) cables. The significant improvement in dielectric properties compared with unfilled polymer is attributed to the large and active interface between the nanoparticles and the polymer. READ MORE

  3. 3. Fabrication and Characterisation of Carbon Nanotube Array Thermal Interface Materials

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Abstract : Atmospheric plasma sprayed (APS) thermal barrier coatings (TBCs) are commonly used for thermal protection of components in modern gas turbine application such as power generation, marine and aero engines. TBC is a duplex material system consisting of an insulating ceramic topcoat layer and an intermetallic bondcoat layer. READ MORE

  5. 5. Thermal Barrier Coatings Failure Mechanisms and Life Prediction

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Krishna Praveen Jonnalagadda; Linköpings universitet.; Linköpings universitet.; [2019]
