  • Helping the Flow of Materials Information
    Acoustic insulating polyamide Rhodia Engineering Plastics, Lyon, France, launches Technyl Star S 218dB1 MSO and 218dB2 MV60, two new polyamide grades that provide more than 4 dB improvement in acoustic insulation over other engineering plastics such as glass-reinforced PP or PA.
    The US company Imi?Tech says that its Solimide lightweight insulating polyamide foam weighs as little as one?quarter as much as alternative approaches to acoustic /thermal insulation, which can result in reductions ranging from 30t on a frigate to 200t aboard an aircraft �
  • Space charge accumulation in coating materials for motor windings under DC high voltage
    Therefore, in this report, we have investigated the space charge behavior in polyamide -imide(PAI) and polyester-imide(PEI), which are usually used as the coating insulating materials for motor windings, under DC high voltage using PEA(Pulsed Electro- Acoustic method) method.

  • Health monitoring of aircraft wiring by acoustic method
    � 1, Figure 7 shows the ratio of reflected energy (in %) when an acoustic wave travels through � The wire was modelled as a copper single strand conductor in polyamide insulation .
  • Space charge behavior in covering insulating material for motor windings under applied voltage of square wave
    Therefore, we tried to investigate the space charge accumulation property in the covering insulating materials under voltage � In this paper, we measured the space charge accumulation in polyamide -imide (PAl) films under a voltage of the square wave by using Pulsed Electro- acoustic (PEA) method.
