Abstract
The adaptable mechanical structures in the form of Shell have found large
developments and use in many applications, especially in the field of smart
structures where the piezoelectric components are used as actuators and sensors.
Many functional constraints prevent the control of a structure by elements
reported on the surfaces of the object. Thus, the piezoelectric components
necessary for the control of the structures will be integrated into this, i.e., in
material, even the material of the wall. Certain work describes the manner and
the performances of structures by using composite materials with thermoset
matrices as structural support and piezoelectric components as the actuator or
sensor elements. The current difficulties in recycling the thermoset materials are
hindering the industrial development of such structures. For this reason, we
propose to use composites with a thermoplastic matrix. Unfortunately, the
current processes of achieving models in smart thermoplastic structures are not
directly exploitable for the integration of components such as the piezoelectric
actuators and sensors which are fragile and sensitive to temperature.
This work evaluates the sizes typically reached in the process transformations
of such composites with a thermoplastic matrix in order to be able to establish
the behavior models for the realized structures. A thermo-mechanic testing
method using dynamic mechanical analysis (DMA) is also proposed.
Keywords: smart thermoplastic manufacturing, cooling rate, thermoplastic
filling time, PZT sensor, piezoelectric properties degradation.
