Full textThis work deals with the determination of ageing markers of high-performance polymers for electrical insulation applications in aeronautics. Most of power cables are made of a successive winding of poly(tetrafluoroethylene) PTFE and poly(imide) PI. This research is focused on the effects of thermal ageing on the physico-chemical structure of these polymers in order to link them to changes in thermomechanical and electrical behaviours. For PTFE, enthalpic and mechanical relaxations are strongly impacted by changes in chemical structure associated to a depolymerisation mechanism. The values of the enthalpy of crystallization and of the amplitude of the ß mechanical relaxation associated with the crystal/crystal transition, can be used as markers of thermal ageing for PTFE. For PI, changes in the chemical structure associated to the scission - recombination mechanism, highlight the formation of heterogeneities, modifying sorption process and electrical charge transport as measured in broadband dielectric spectroscopy. The evolution of the diffusion mechanism and of the activation energy of the electrical conductivity, constitute pertinent ageing markers for PI

Full textThis thesis work proposes a systematic methodology dedicated to the evaluation and comparison of CO2 emissions’ reduction for hybrid electric vehicles with different architectures and different levels of functionality. A sizing methodology has been developed, which is based on the definition of the requirements for the dynamic performances of vehicles, on the development of scaling algorithms in order to generate the dataset for the powertrain components (battery, electric motor, engine), and on the application of procedures for the sizing of a vehicle under CO2 emissions’ minimization constraint. The energy consumption evaluation of the different vehicle configurations, which were previously sized, is founded on the definition of a variety of vehicle’s type of use, as well as on the implementation of an optimal energy management strategy, the Pontryaguin’s Minimum Principle. These methodologies have been applied to a conventional vehicle architecture, which has been used as a reference for dynamic performances and energy consumption, and to a hybrid parallel pre-transmission architecture, which has been defined in two configurations, a plug-in hybrid and a non plug-in full-hybrid

Full textThe aim of this study is to improve the description of solid organic insulators or polymers ageing under electrical stress. With this objective in view, the different ageing scenarios existing in the literature were analyzed, compared and improved. This theoretical study showed that many parameters related to their heterogeneous structure and the distribution of their properties were neglected in order to simplify the modelling. This study presents a new approach in the description of solid organic insulators ageing by taking into consideration their experimentally demonstrated structural complexity. In this approach, the polymer material has been assimilated to a set of sites representing different energy states, thereby different properties as well as ageing rates depending on each site. The principal parameters involved during the ageing process, such as the specific volume variation, the dielectric strength evolution and the local value of the electrical field have been defined. The expression of the retardation time specific to each elementary ageing process has been established. Finally, a distributed form of those retardation times has been presented. Our "phenomenological" approach is thus a multi-sites one permitting, along with an experimental study, to establish an equation relating the life time of polymer electrical insulators to the different parameters at play, all along respecting their distribution over the entire set of sites within the polymer

Full text50 million people suffer from head trauma each year worldwide. The shock (external mechanical stress) acting on neural networks insided the brain can lead to the appearance of traumatic brain injuries (TBI). In the short term and long term, this process can lead to neuroinflammation and the manifestation of pathologies such as Parkinson’s disease or Alzheimer’s disease. This thesis aims to develop a stretchable microsystem for the electromechanical study of neural networks in vitro. Such a microsystem must integrate insulated electrodes which are mechanically robust on the stretchable support. The first part of this work consisted in studying the direct metallization on PDMS using physical masking. Next, a patterned photoresist (SU-8) thin film was then used between the PDMS and the metals. The stiff SU-8 shields the metallization from strain—which now occurs in the adjacent PDMS. In order to avoid cracks under mechanical stress, the architecture and orientation of the electrodes has been studied and validated by a physical model. The second part was the fabrication of a PDMS/SU-8/Cr-Au/Parylene stretchable microsystem by photolithography using a planar process developed during the thesis work. The microsystems is compatible with MultiChannel System© commercial device which allows the visualization and recording the nerve impulses of a mature neural network. A microfabrication process has been developed with 3 photolithography steps on a PDMS substrate. The functionality of the microsystem has been validated by the visualization of electrical responses of neural network at 12 days in vitro (DIV). In addition, this microsystem demonstrates a signal/noise ratio comparable to commercial MultiElectrode Array (MEA)
