Provided is a thermoplastic composite, a method for preparing a thermoplastic composite, and an injection-molded product. The thermoplastic composite comprises 35-75% by weight of a thermoplastic resin, 5-45% by weight of a non-cellulosic organic fiber, and 5-20%) by weight of hollow glass microspheres, based on 100% by weight of the total weight of the thermoplastic composite.

Thermoplastic composite, method for preparing thermoplastic composite, and injection-molded product

A system () for monitoring a temperature of an electrical conductor of an electrical cable and including a temperature sensor unit () and a transceiver unit (). The temperature sensor unit () is located inside the first (semi)conductive layer and includes a micro-controller (), a temperature sensor (), an energy harvest sub-unit () and a wireless transmitter layer (). The temperature sensor () is adapted to detect a first signal (S) representing temperature of the electrical conductor and to supply the first signal (S) to the micro-controller (). The transceiver unit () is located outside the first (semi)conductive layer and includes an energy transmitter () and a wireless receiver (). The energy harvest sub-unit () is adapted to harvest electromagnetic power from the energy transmitter () and to provide electrical power to the micro-controller (). The wireless transmitter () is adapted to being engaged with the wireless receiver () under the control of the micro-controller () to transmit a second signal (S) converted from the first signal (S) to the wireless receiver (). The energy harvest sub-unit () and the wireless transmitter () are designed to have different working frequency.

Systems and methods for monitoring temperature of electrical conductor

A system for monitoring temperature of an electrical conductor () enclosed in at least a (semi)conductive layer () comprising: a passive inductive unit (), and a transceiver unit () and a control unit (). The passive inductive unit () includes at least one temperature sensitive component and is configured to have a resonance frequency and/or Q value that vary with temperature of the electrical conductor (). The transceiver unit () is configured to be electromagnetically coupled to the passive inductive unit () and to send out a signal representing the resonance frequency and/or Q value of the passive inductive unit (). The transceiver unit () is further configured to communicate with the control unit () which ascertains the signal representing one or both of the resonance frequency and Q value, and which determines a value of the temperature of the electrical conductor () based on the ascertained signal representing one or both of the resonance frequency and Q value.
