Materials used for aircraft fuel tanks are most often metallic. But with technological advances and outbreaks, some new carbon-based composites have emerged that show equivalent thermo-mechanical performance for lower weight and cost. Thus, such materials could become attractive alternatives for fuel tanks of new generations of aircrafts. However, the introduction of new composites justifies new inquiries...
The motor of an electric vehicle and its equipment are connected to the battery via a junction box that contains power relays that ensure current flow when closed but can break the current in abnormal situations. The contacts of such relays have to ensure and maintain a low contact resistance and support a shorting current of a few kA and an acceptable breaking capacity under a normal load of a few...
In the field of electrical contacts, carbon has been rarely investigated but carbon is more and more used in the automotive field. This is especially true in membrane switching technology, which is commonly used in the control field such as in remote controls, automotive switches, mobile phones, etc. This technology is based on a mobile contact, mounted on flexible elastomeric parts which are pressed...
Membrane switching technology is commonly used to operate electrical apparatus such as remote controls, automotive switches, mobile phones, etc. This technology is based on a movable contact, mounted in a supple elastomer frame which allows the contact to be pressed against a stationary contact, mounted on a Printed Circuit Board (PCB). The material of the movable contact is typically a carbon-loaded...
In membrane switching technology, a mobile contact, mounted on supple elastomeric parts is pressed onto a static part of the PCB by means of a knob. This technology is commonly used for keyboards in stationary applications where the contact material is made of carbon film while the PCB is coated with a gold layer. For automotive applications that require high reliability and low cost switches, further...
Electrostatic shock is a very common feature in an automotive environment. Such a phenomenon may be detrimental for the embarked electronic devices and/or the passengers. The work presented in the following deals with this latter aspect and consists of the research of physical solutions able to avoid the human body voltage rise up and its associated discharge. This paper is focused on the determination...
