Texto completo da fonteThe delamination of thermoplastic matrix composites is studied by comparing the behaviour of unidirectional specimens of three of these (AS 4/PEEK, AS 4/PPS and AS 4/PES), with that of two carbon/epoxy materials (T300/914 and IM6/6376). First, the influence of loading mode is examined using fracture mechanics parameters and relating these to failure mechanisms. Results are presented for mode I and mode II (both static and fatigue), mixed mode and mode III tests. In the case of mode II, the use of four specimen configurations leads to an improved test methodology. Second, the influence of test temperature and loading rate are studied. Finally, the influence of semi crystalline matrix structure in the PEEK and PPS composites is evaluated. These tests are complemented by a critical discussion of the application of delamination tests to thermoplastic matrix composites

Texto completo da fonteThe study objective is to investigate C/PEEK composites manufacturing by thermocompression by gauging two textile semi-products and by taking advantage of the EdyCO pilot capabilities featuring Cage System(r) technology. This process enables to reach high heating and cooling rate and to realise complex thermical cycles that offer new optimisation perspectives of application of thermoplastic resin composites. This work is about the study of manufacturing of two semi-products, the first one being a dry fabric of carbon powdered by PEEK, the other one being a multiaxial of continuous commingled yarns of C/PEEK. The first part of this work is focused on the study of the influence of semi-products and process parameters on consolidation phase of composite plates. Indeed, use of EDyCO pilot enabled to investigate high manufacturing temperature in order to suggest parameters propitious to reinforcement impregnation. The obtained results show that matrix degradation influences consolidation and that commingled structure may be harmful to impregnation. Cooling phase of thermo-compression cycle represents the second part of the this study. Thus, neat and reinforced PEEK crystallization and crystallization kinetics were characterised during anisotherm and isotherm cooling. A unified model was designed to predict crystallization kinetic of both neat and reinforced PEEK. This model describes PEEK crystallization as resulting from the contribution of two mechanisms to debrief of double melting peak phenomena. The influence of degradation is also analysed. To conclude this work, adapted optimal manufacturing cycles are proposed and mechanical properties are evaluated

Texto completo da fonteNanocomposites based on polymerie matrix and clay reinforcements have created a huge effort from academic and industrial researches. This investments are recompensed by the significant amelioration of several properties in comparison to conventional composites. The present work is devoted to a key parameter which is the elaboration conditions, in relation to structural organizations and mechanical properties. The first part deals with the clarification, in case of Nylon 6 nanocomposites, of the relationship existing between thermo-mechanical history and crystalline organization. Those elements are then used in properties optimization of blown films. The second part of the work tackles the elaboration of nanocomposites with a biodegradable polymerie matrix (Polylactide) and an unmodified clay using an original process of water injection, in collaboration with the university of Louvain La Neuve (High Polymer Unit). The obtained films exhibit a dispersion of fine clay aggregates intercalated by PLA (tactoïdes). The presence of this dispersion gives raise to a remarkable mechanical behavior, especially in term of ultimate properties

Texto completo da fonteThis thesis has been carried out as part of the project Fiabilin, which includes 15 different academic and industrial partners, with an aim to develop industrial production of polyamide-11/flax biocomposite. The purpose of this work is to determine multi-scale performances of 100% biosourced composite, in order to substitute composite materials containing glass fibers and/or matrix derived from petroleum. First, we highlighted the flax fiber sensibility toward processing cycles (time and temperature), from mechanical and biochemical structure aspects. Then, we revealed the capacity of PA11-flax association to produce competitive mechanical properties compared to others usual composites. Fiber-matrix interface of the biocomposite was studied at micro and macro scales, showing a higher compatibility than some flax-thermoset resin systems. The end-of-life of the biocomposite was considered by recycling with successive grinding and injections. Then stiffness and strength at break of short fiber biocomposites thus obtained are similar to PPgMA-flax composites, whereas a strong increase of the strain at break according to the number of injection cycles was observed. A life cycle analysis of some composites production steps shows lower environmental impacts of PA11-flax when sizing was made through equivalent material stiffness

Texto completo da fonteThe present work is a contribution to the phenomenological modelling of fatigue non-linear cumulative diffuse damage in short glass fibre reinforced thermoplastic matrix composites. In such materials, fatigue damage kinetic exhibits three stages, namely: i) material softening and damage initiation, ii) coalescence and propagation of micro-cracks, iii) macroscopic cracks propagation and material failure. The proposed model is built in the framework of the continuum damage mechanics and aims at predicting these three stages of the damage evolution. It extends the previous approach and takes into account the important stiffness reduction observed during the first damage stage. The above is modelled by the integration of a combined Norton-like power law and an exponential law expressing the damage rates as a function of the associated thermodynamic dual forces. The model has been formulated in terms of strain energy, so that makes easy its numerical implementation into the finite element code Abaqus/Standard through a user defined material subroutine UMAT. Damage evolutions predicted by the developed model reproduce well those observed for this kind of composites under cyclic loading. Two identification strategies are developed. The first identification strategy based on homogeneous tensile fatigue tests performed in the longitudinal and transversal directions of a PA6-GF30 and a PP-GFL40. A second identification strategy based on the use of optical whole-field displacement/strain measurements by digital image correlation coupled to an inverse method from one single coupon

Texto completo da fonteThe "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
Fischer, Guillaume. "Matériaux composites aéronautiques hautes températures à matrice bismaléimide renforcée". Thesis, Lyon, INSA, 2015. http://www.theses.fr/2015ISAL0117/document.
Texto completo da fonteAeronautics use more and more composite materials to reduce structures weight, in order to improve performance and to limit fuel consumption. Polymer matrix composite materials represent today more than 50% of last generation civil aircrafts structure (A350, B787). Most of thermoset matrices are epoxies with service temperatures below 110°C for long time services. To further optimize the composite part ratio, it is now necessary to use those materials in structural parts exposed to higher temperatures, for instance, near engines. Among high performance thermoset matrices, bismaleimides offer potential in service temperature up to at least 200°C, but their brittleness makes them non-suitable for structural applications. Epoxy-based composite materials have gone through improvements, increasing their toughness by mixing with soluble and non-soluble thermoplastics to hold in delamination crack propagation. Starting with methods and knowledge from epoxies toughening strategies, this work is dedicated to develop toughened bismaleimide systems and to identify relevant parameters to reach this aim
