Texte intégralThis thesis focuses on the development of a numerical model for the preform impregnation during the VARI (Vacuum Assisted Resin Infusion) process for the manufacturing of a composite material. The in situ characterization of the mechanical behavior in the thickness direction of a preform (real infusion tests) was compared with an ex situ characterization by a universal testing machine. The preform behavior was characterized for different parameters such as loading type, saturation state, influence of fluid viscosity and strain rate. All the tests revealed the viscoelastic behavior of a woven fabric during its decompression in the impregnated state, leading to the definition of a non-linear viscoelastic constitutive law of the woven fabric during this phase. To extend the use of this mechanical constitutive law to a wide range of fabrics, the same experimental approach was applied to the case of a random mat fabric with non-linear elastic behavior. The generalized form of the constitutive law is adapted to the description of the two types of fabrics while the potential viscoelastic effects are taken into account according to the fabric type. After the implementation of the new constitutive law in a numerical code for the simulation of a mold filling process, the comparison between numerical and experimental results has proved the reliability of the new numerical model for these two reinforcements with distinct architectures

Texte intégralCarbon fiber reinforced composites (CFRC) have been successfully developed since decades as efficient and lightweight materials for various innovative applications and mostly for transport applications. Due to the low electrical conductivity of the polymer matrix of CFRCs, a better functionalization of such materials, such as developing a metallic coating on the CFRC structure of an aircraft, brings added values that contribute to a longer life and new performances such as the lightning strike protection (LSP) performance. The major objective of this PhD research program is to improve the metallization of a CFRC substrate by a new approach that focuses on the development of a hybrid layered structure made of CFRC and a biphasic sublayer embedded onto the top surface of this structure, prior to a cold spray metallization. To achieve this objective, the research works rely on an experimental task and a computational analysis which can be divided into three significant contributions:The first experimental part focuses on the development of a biphasic sublayer in between the CFRC substrate and the metal coating. This sublayer consists of a mixture of a polymer (Thermoset Epoxy, Thermoplastic Polymethyl methacrylate) with a micron sized metal powder (Al, Cu). The vacuum assisted resin infusion process is used to produce the hybrid CFRC with the biphasic sublayer on its top face. Prior to the cold spray metallization, the thermo-physical properties of the hybrid CFRCs/biphasic sublayer are characterized using a differential scanning calorimetry (DSC) analysis and a thermal conductivity measurement. The mechanical properties of the hybrid CFRC system are characterized by means of mechanical testing (impact test, tensile test, three-point flexural test, lap-shear adhesion test).The second part of this PhD work investigates the metallization of the hybrid system CFRC/biphasic sublayer using the low-pressure cold spray Dymet 423 system. Copper, aluminum, zinc, and tin powders are used as coating material due to their good electrical and thermal conductivity. Powder mixtures made of these metals and alumina powders (Al2O3) are considered as other potential materials for the cold spray metallization of the biphasic sublayer/CFRC system. An embedment of the cold spray powders onto the biphasic sublayer is found to ease the coating formation, except for the Cu cold spray powder. A continuous 60 μm thick coating of Sn+Al2O3 is obtained onto the biphasic TS-Cu sublayer, that shows the feasibility of surface functionalization of CFRC via a biphasic sublayer and a low-pressure cold spraying.The third part of this PhD work focuses on a phenomenological analysis of the mechanical response of the TS biphasic sublayer during the high-speed collision of the cold spray process. This part aims to depict further improvements through a computational analysis. The erosion issue of the epoxy matrix of the sublayer is found to govern the unsuccessful coating formation onto the thermoset sublayer. Therefore, to find out suitable biphasic polymer materials, a simulation of a Cu powder collision onto thermoplastic media (TP and TP-Cu) has been investigated, that shows a good embedment of the Cu powder onto the TP substrate via a mechanical interlocking (metal-to-resin bonding). The copper particles of the biphasic TP-Cu sublayer enable to promote a plastic deformation of the sprayed Cu particles and is conducive to a bonding formation and coating growth. Finally, to provide a proof of concept, experimental HPCS metallization onto biphasic sublayers made of a TP matrix are performed. A continuous coating formation of spherical Cu, dendritic Cu, and Cu+Al2O3 is obtained onto TP-Cu sublayer, with a thickness of 95 µm, 231 µm, and 114 μm respectively. Thereby, the feasibility of the metallization of CFRC via a TP biphasic sublayer and a high-pressure cold spray deposition has been demonstrated
