Epoxy resin is widely used in high voltage apparatus as insulation due to its excellent mechanical, electrical and chemical properties. In recent years, researches on epoxy resin/nanocomposites have shown that the presence of nano-size filler in epoxy resin system can improve electrical, thermal and mechanical properties significantly. In the present paper, the epoxy resin containing nanosize SiO2...
Atomic-scale computational materials engineering offers an exciting complement to experimental observations, revealing critical materials property data, and providing understanding which can form the basis for innovation. This contribution reviews the current state of atomic-scale simulations and their capabilities to predict mechanical, thermal, and electric properties of microelectronics materials...
This paper presents for the first time the complex dielectric permittivity and loss tangent measurements for a selection of advanced polymer-based thermoplastics in the Q-band, V-band and W-band frequencies. These plastics are reported to have exceptional mechanical, thermal and electrical properties and are extensively used as electrical insulating materials, often operating at high voltages. With...
The novel multiaromatic epoxy resin and hardener was synthesized and characterized. The mechanical, thermal, electrical as well as flame retardant properties of cured epoxy resins were systematically investigated. Experiment results indicated that the cured novel multiaromatic resins exhibited very good mechanical properties, good electrical properties, high glass transition temperature, good dielectric...
Polymeric materials like mineral filled and fibre reinforced epoxy resins were applied in many power apparatus for electric insulation. Outdoor and indoor insulation systems in condition of high humidity, partial discharges (PD) and mechanical overstresses lead to lifetime reduction. Aims of this investigation is the extension of operating time due to economical reasons, reduction of maintenance and...
The introduction and development of biaxially-oriented poly(ethylene naphthalate) film (PEN film) in Japan has been compared with the biaxially-oriented poly(ethylene terephthalate) film (the PET film), which is usually mass-produced for electrical and audio-visual uses. Its physical, mechanical, electrical, thermal, chemical, optical and surface properties and radiation resistance were reviewed and...
