Mahmoud, Bassam. "Modélisation d'impacts sur des stratifiés composites unidirectionnels et hybrides". Thesis, Toulouse 3, 2017. http://www.theses.fr/2017TOU30212.
Testo completoToday, composite materials are largely used in the manufacturing of aeronautical structures, in order to lighten their weight. Impact on composite structures is one of the most detrimental loading. The present study aims to develop a predictive modelling of impacts on thin unidirectional laminates in order to, firstly, better understand the damage mechanisms involved, and, secondly, be able to provide guidance for a strength improvement of these structures. First, an explicit finite element modelling of unidirectional laminates is developed based on the work of F Pascal dealing with impact modeling on helicopter blades. Thus, a new element that can represent the impact response of unidirectional plies is formulated. The behavior of the bundle of fibers is modeled with rod elements stabilized with specific 2D elements. The degradation is managed using damage based on experimental observations. The parameters of the proposed modelling strategy are identified on the basis of experimental tests carried out on T700/M21 and HTA7/913 composites. The results provided by the modeling are then validated by a comparison with experimental low velocity impact results. Finally, in order to improve the laminate strength, low velocity and medium velocity impacts on hybrid unidirectional/woven composite laminates are studied experimentally and with the developed modelling strategy

Testo completoWe have studied the conductivity of the composite material made of micron-sized nickel particles embedded in a silicone elastomer matrix in response to the applied pressure, temperature and magnetic field. The composite was cured at 80°C or at the ambient temperature and in the presence of an external magnetic field, in such a way that the magnetic particles formed structures aligned with the field. The samples cured at room temperature appeared to be non-conductive at zero pressure but very sensitive to the applied pressure. The resistance of these samples can vary from a few G at zero pressure to a few for a pressure ranging between 20 and 200 kPa, depending on the nature of conductive particles. For the same type of the composite, we have also obtained a very strong magnetoresistance - more than four orders of magnitude variation in resistance for a field ranging between 0 and 200 kA/m. However, the samples structured at 80°C show a low initial resistance at the end of cooling, and are much less sensitive to the applied pressure. We used these samples to study the thermoresistance: while heating, the resistance increases from a few to a few G We have developed a model to predict the behavior of these piezoresistive materials, which takes into account the surface roughness and the thickness of the oxide layer. Using this model, we characterized the residual thickness of the polymer layer between particles as well as the behaviour of such surface layer in the presence of a mechanical stress

Testo completoThis thesis is focused on the conception of new tunable ferroelectric/dielectric compositematerials. Dielectric granules (MgO, TiO2) obtained by spray-drying are dispersed in a ferroelectricmatrix (Ba1-xSrxTiO3). Mixing powder is then densified by Spark Plasma Sintering (SPS). An originalapproach is developed in order to determine parameters linking the microstructure to the physicalproperties for each step of the elaboration - characterization - modelling optimization procedure.The adopted strategy is based on i) specific SPS properties which provide an accurate control of theinterfaces between each components; ii) potentialities offered by X-ray microtomography to describethe internal 3D microstructure of the composite materials during the key steps of their elaboration.Associated with powerful image processing tools, it allows to obtain relevant elements guiding theoptimization and understanding of the final properties; iii) the development of a 3D numerical modelof tunability applied directly to the real geometry which has been extracted from 3Dmicrotomography images. This step is essential to understand the origin of the redistribution of theelectric field between the different phases. Numerical results are directly compared to experimentalmeasurements

Testo completoAmong all systems for electrical storage, electrochemical devices are interesting because they turn chemical energy into electrical energy. Supercapacitor and Li-ion battery have high power density and good energy density, respectively. The topic of the present work is the preparation of composite electrode material MnO2/C for supercapacitor, SnO2/C for Li-ion battery and synthesis of porous SiC. This could be achieved starting by the synthesis of mesoporous carbon (900m2/g) following a hard template method. At first, the evaluation of electrochemical performances of composite electrode material for supercapacitor shows two different behaviours versus the ratio of MnO2. We could observe an optimal ratio for which capacitance was maximal (900F/g). Secondly, the volumic variations occurring while charge/discharge of SnO2/C electrode materials are contained by the carbon matrix. In spite of limited electrochemical performances for pure SnO2 electrode material, the cyclability of SnO2/C electrode materials is enhanced. At last, the synthesis of porous SiC can be achieved by the thermal reduction of SiO2/C composite using Mg as reducing agent. The as-prepared material is a replica of silica template

Testo completoThe porosity of a composite plate in carbon / epoxy of type RTM is known by used of tomography X. A method of determination of this porosity by measure of the mitigation of the longitudinal waves through the thickness of this kind of plate is proposed. These measures are made on surfaces of different sizes (from some cm2 to some mm2) and allow the obtaining of cartographies. A correspondence porosity (tomo X) - Mitigation (US wave) is deducted and analyzed according to the structure of the composite material. In every case, we estimate the quality of the obtained relations and we deduct the limits of validity of the correspondence between porosity and mitigation. First results of acoustic tomography are obtained

Testo completoFacing the worldwide environmental, social and economic crisis awareness, the possibility ofreinforcing composites by a lignocellulosic textile reinforcement, the coconut leaf sheaths fromCocos nucifera L. was assessed in this work. The exploratory phase of sheaths characterizationhas shown that this resource forms a two-way textile made up of cellulose mostly. In contrast toclassic vegetable reinforcements, it is less hygroscopic, lighter with best tensile mechanicalproperties in preferential fibers directions. About the experimental campaign on the treatmentseffect, xylanase and laccase treated sheaths show a slight surface chemical change. Pyrolysedfibers are more hydrophobic but less resistant translating a damaging of them. Lime treatedsheaths show a higher thermal stability. Thus, raw sheaths were retained to reinforceparticleboards, the temperature of panels manufacture being lower than the start degradationtemperature of the raw sheaths. The two-faces panel covered with raw sheaths top part forms themost promising candidate to develop thermal eco-insulator. Some of its mechanical and physicalproperties fulfill american and european standards. Its thermal properties are similar to the onesnoticed in the bibliography for low density lignocellulosic particleboards
Senghor, Fiacre Djonkone. "Identification des propriétés anisotropes des matériaux complexes : application aux matériaux composites stratifiés". Thesis, Nantes, 2017. http://www.theses.fr/2017NANT4002/document.
Testo completoThe works presented in this thesis focuses on the identification of anisotropic electrical properties of complex composite materials. They aim to contribute to a better control of the impact of manufacturing process parameters, different architectures, formulations and fibres filling rate, etc., on the electrical behaviour of these composite materials. They inscribe themselves in the frame of the FUI ACCEA research project funded in part by the region Pays de la Loire. This project aims to produce a multi-functional composite material of a new type of thermoplastic matrix loaded with carbon graphite which would see its electrical and thermal properties improved without degrading the mechanical properties. From then one of the main difficulties of the designer is to find innovative implementation tools, to improve the thermal and electrical properties of these composites non-intrusive and non-destructive to their mechanical properties with less cost. It is in this logic that this PhD work is interested in modelling and experimental measurement of the electrical conductivity tensor of this composites to provide an help to the decision on the choice of matrix, of the weave, the implemented method, etc. The comparison between the simulation and experimental results gives a good concordance
