Der volle Inhalt der QuelleNowadays, composite materials make it possible to reduce the mass of parts and are widely used in the aerospace, aeronautics and automotive industries. In addition, the multilayered reinforcement of composites allows the design of thick structures such as the fan blades of aircraft engines. However, many defects can occur during the forming process of multilayered reinforcements, such as the wrinkling problem. Research on the formation of wrinkles, as well as on the tufting technology to improve the mechanical property of multilayered reinforcements in the direction of thickness are presented in this work. The first part of this report is a study of the formation of the wrinkles of multilayered reinforcements subjected to out-of-plane bending. Firstly, the influence of the different orientations of the layers on the formation of wrinkles is explored. The relationship between the load applied to the fabric and the creation of wrinkles is thus shown. The second chapter compares two types of weaving pattern on the drapability of the composite. The third part consists of developing two numerical models adapted to simulate the forming of tuft-bonded composite reinforcements. These approaches involve the use of a stress resultant shell element to represent each layer of reinforcement and bar elements to represent the tufting yarn. These models require a specific contact algorithm to manage the interaction between the reinforcement and the tufting yarn. Finally, the last part consists of validating the models by comparing simulations and experiments

Der volle Inhalt der QuelleThe aeronautical industry faces new challenges regarding the reduction of fossil fuel consumption. One way to address this issue is to use lighter composite materials. The ability to predict the geometry and the mechanical properties of the unit cell is necessary in order to develop 3D reinforcements in composite materials for these aeronautical applications. There is a difficulty to get realistic geometries for these unit cells due to the complexity of their architecture. Currently, existing tools which model 3D fabrics at a meso scale don't take into account manufacturing process influence on the shape modification of the textile structure. There is already some numerical tools that can model the braiding or knitting process, but none have been developed for weaving so far. Consequently, this study deals with the numerical simulation of the weaving process to obtain a deformed dry fabric structure. During the weaving process of E-glass fabrics, achieved in our laboratory, it has been observed that large deformations led to the modification of transverse section of meshes, or local density changes, that can modify the fabrics mechanical resistance. For this reason, a numerical tool of the weaving process, based on finite element modelling, has been developped to predict these major deformations and their influences on the final textile structure. The correlation between numerical results and fabrics produced with glass fibres has been achieved for plain weave and 2-2 twill

Der volle Inhalt der QuelleThe "Resin Transfer Molding" (RTM) process is very largely used for the industrial production of composites materials with thermoset matrix. Indeed, it’s used by many fields such as the automotive and aeronautics. In this work we adapted this process to the manufacture of composite materials with thermoplastic matrix in order to answer the ecological and economic criteria imposed on industries. For that several steps were necessary. The first was the selection of a robust chemistry, adapted to the requirements of the process (low initial viscosity of the reactive system, polymerization time, etc). The selected chemistry, was the ring opening polymerization of ε - caprolactam to obtain polyamide-6 (PA-6). Rhéo-kinetics studies, as well as the physicochemical characterizations of a Pa-6 obtained at the laboratory were carried out. Following this step, tests in conditions of process were carried out with the use of dedicated pilot equipment. These tests were the source of modifications and optimizations of certain parameters of the process. The third step, consisted with the production of composite parts with a reinforcement of the type: unidirectional glass fabric. This production was followed mechanical and physico-chemical tests in order to evaluate the properties of these parts. Various sizing of the glass fabric were studied with, for objective, to determine which to offer the best properties. During this study we observed the low impact of the sizing on the chemistry of PA-6. To finish, we set up a reactive sizing which will allow a better interaction fibre/matrix

Der volle Inhalt der QuelleThe deformation of textile composite reinforcements is strongly conditioned by their fibrous composition. Classic plate and shell theories are based on kinematic assumptions that are not verified for textile reinforcements. Experiments show that the slippage between fiber (layer) in the thickness makes the specificity of fibrous materials. The RTM process (one of the forming process) is widely used to obtain composite parts with complex geometry is with great importance. In order to optimize the manufacturing of product, numerical models are necessary. Therefore, a 3D shell approach specific to fiber reinforcements is proposed which is based on two specificities: the quasi-inextensibility of the fibers and the possible sliding between the fibers. This approach is developed in the frame of continuum-based shell, the new assumption who based on the conservation of the thickness is applied to the kinematic equation. The theory of virtual power reflects the specific deformation of the fibrous reinforcements. It considers the tensile and bending stiffness of the fibers and the in-plan shear stiffness. The friction between fibers is taken into account in a simple way in connection with bending. The present approach is based on the real physics of the deformation of textile reinforcements. It simulates the 3D deformations of textile reinforcements and provides displacements and deformations for all the points along the thickness of the fabric and simulates the correct rotations of the material director. Finally, experiments and simulations performed on multilayer reinforcements are presented in this work, and a new method of experimentation is proposed

Der volle Inhalt der QuelleManufacture processes modeling of woven fabrics composites is a major stake for state-of-the-art industrial parts, where their usage is intensifying. Control of all the manufacturing stages of ceramic matrix composites, particularly the forming and pyrolysis steps, is essential. Understanding and simulation of the mechanical behavior at each stage is required to optimize the final product performances. Two macroscopic modeling approaches of thick woven fabric reinforcements are detailed: a continuous classical one and a semi-discrete one. An initially orthotropic hyperelastic constitutive law is thus established. This law is based on a phenomenological observation of the main fabric deformation modes, from where physical invariants of the deformation are suggested. The required material parameters identification is explained. A modified version of this law, without any tensile energetic contribution, is implemented in a semi-discrete element where the tensile work is taken into account by bars that discretize the real weaving. Thick woven reinforcements are highly anisotropic materials due to the large ratio between the tensile rigidity and the others. Their numerical modeling highlights spurious phenomena and limitations related to this specificity. The tension locking is firstly tackled. A remedy based on an enhanced assumed strain finite element formulation is suggested for classical continuum and semi-discrete elements. Problems linked to bending-dominated numerical simulations are brought to attention : transverse hourglassing and lack of local bending stiffness. For the transverse hourglassing situation, two stiffening technics are proposed : averaging the dilatation through the whole element or adding a supplementary tangent material rigidity in a specific direction. The local bending stiffness problem is solved by calculating the curvature inside the element by using rotation free plates. The induced bending moment leads to supplementary internal loads. Finally, the elastic springback following the pyrolysis of the polymer matrix with ceramic precursors is modeled. The constitutive behavior is experimentally identified with a transverse isotropic hyperelastic law. Added to the initial reinforcements’ hyperelastic law, with the preformed fabric as reference configuration, the pyrolysis induced deformations can be visualized. This final model is compared with experimental results

Der volle Inhalt der QuelleAlthough woven reinforced composites are experiencing rapid growth across various engineering and industrial domains, their widespread adoption is often hindered by challenges in accurately predicting their mechanical behavior. This obstacle primarily stems from the heterogeneous nature of these materials. Consequently, employing multi-scale approaches becomes imperative to predict their overall response under complex loading conditions, incorporating detailed descriptions of microstructure and the constitutive laws governing their components. However, effectively incorporating these methodologies into real-scale applications, particularly within FE² analyses, remains challenging due to the significant computational requirements they entail. This challenge intensifies when numerous direct calculations are necessary for testing various configurations, a critical aspect in optimization, inverse analysis, or real-time simulations. The need for such calculations adds to the computational demands, posing a significant obstacle to integrated into practical applications. To address these issues, while considering the scale effects, this thesis aims to develop efficient numerical tools to achieve accurate and fast predictions of woven composite response. First, we develop virtual twins (multiparametric solution) for real-time prediction of composite response, using non-intrusive Proper Generalized Decomposition (PGD) based methods. This aims at providing an accurate approximation of high-dimensional problems, that involved several microstructural parameters, with limited dataset. These multiparametric solutions are constructed for both linear and nonlinear behavior including history- and rate-dependent behaviors. Second, we develop an approach based on ANN to perform a macroscopic surrogate model of composites. This model, referred to as Multiscale Thermodynamics Informed Neural Networks (MuTINN), is founded on thermodynamic principles and introduces specific quantities of interest that serve as internal state variables at the macroscopic level. This captures efficiently the state and evolution laws governing the history-dependent behavior of these composites while retaining the thermodynamic admissibility and the physical interpretability of their overall responses. This approach has successfully associated with FE code, streamlining the application of multiscale FE-MuTINN approach for composite structure computations. The prediction capabilities of the proposed approach are demonstrated across the material scales, exemplified through diverse instances of woven composite structures. These applications account for anisotropic yarn damage and an elastoplastic polymer matrix behavior. This promises a potential solution to alleviate the computational challenges associated with multiscale simulations of large composite structures and paving the way for the development of a hybrid twin solution

Der volle Inhalt der QuelleContinuous fibre composites (carbon, glass) are regularly used in the transport industries (automotive, aeronautics) for their excellent mechanical performance in relation to their mass. While woven reinforcements are widely used and studied, there is a growing interest in stitched reinforcements called "non crimp fabric" (NCF). These reinforcements consist of juxtaposed plies of unidirectional fibres , non-woven, but sewn together with a stitching thread. They allow a greater variety of fibre orientation and optimize the properties of the composite by reducing fiber interweaving. The manufacture of composite parts by automated processes such as RTM (Resin Transfer Molding) involves the forming of fibrous reinforcements to obtain complex 3D geometries. The draping of NCFs is strongly impacted by the presence of the stiching thread. The development of simulation tools should enable the manufacture of these products to be optimize. This work focuses on the mechanical role of stitching during forming. The study focuses on experimental tests and finite element simulations in explicit dynamics of various NCF reinforcements. Different modelling approaches at macroscopic scale are proposed for NCFs, based on previous work on woven reinforcements : integration of stitched thread and the stitch pattern into the laws of behaviour; development of models mixing continuous finite elements for fibre modelisation, and semi-discrete models for the stitch. The performance of these different approaches is compared with experimental results. Finally, a new contribution is add to consider the bending rigidity in the plane of the fibrous reinforcements by generalizing the use of finite elements shell called "rotation-free" for the calculation of all the curvatures (out of plane and in the plane)
