Advanced ceramics appear to be a very important resource for the development of many new technologies (fuel cells, nuclear fusion…) and in many manufacturing processes. An important issue in the construction of ceramic components is related to their joining methods. When size and complexity of the components grow, it is impossible to sintherize...

The results of an experimental investigation on carbon/carbon composites (C/C) bonded joints tested in shear at room temperature, under seven different configurations, are presented. The samples have been joined by an epoxy adhesive (AV119): this adhesive is not to be considered as a suitable joining material for C/C for high temperature...

The main insulating system components of stator windings of rotating electrical machines are organic enamel and impregnating resin. When power electronic converters supply motors, the stator insulation system is subjected to voltage waveforms such as PWM composed by trains of pulses. Due to reflection phenomena, overvoltage can be associated to...

The insulating system of stator windings of rotating electrical machines are usually based upon organic enamel as primary insulation and impregnating resin used for the secondary insulation. When the motors are supplied by power electronic converters, the stator insulation system is subjected to voltage waveforms such as PWM composed by trains...
