In-Situ Fiber-Optic Temperature Field Measurement During Thermoplastic Composite Welding and Other Applications

An in-situ fiber-optic temperature field measurement is disclosed that can allow process monitoring and diagnosis for thermoplastic composite welding and other applications. A distributed fiber-optic sensor can be permanently embedded in a thermoplastic welded structure when it is welded and left there to perform lifelong monitoring and inspection. The fiber optic sensor can include a dissolvable coating, or a coating matched to the composite material to be welded. Other applications include in-situ fiber-optic temperature field measurement on thermoset composite curing (autoclave), for thermoplastic and thermoset composites during compression molding, and for fiber-optic field measurements on freeze/thaw of large items of public health interest, such as stored or transported foodstuffs.

Method for joining a device to an object with the aid of ultrasonic vibration energy and device and installation suitable for the method

A method for joining a device to an object with the aid of a combination of ultrasonic vibration energy and induction heating, wherein the device includes a portion of a thermoplastic polymer and a susceptor additive wherein this portion is at least partly liquefied or plasticized through the ultrasonic vibration energy in combination with the induction heating and wherein the joining includes establishing a connection between the device and the object which connection is at least one of a positive fit connection, a weld, a press fit connection, and an adhesive connection. The induction heating is applied for rendering the device portion suitable for absorption of ultrasonic vibration energy than other device portions by raising its temperature above the glass transition temperature of the polymer. The ultrasonic vibration energy is used for liquefying or at least plasticizing the thermoplastic polymer of the named device portion.
