The works aims to correlate some morphological parameters and the mechanical properties in composite systems based on polymer matrix reinforced by submicronic inorganic fillers. The thought process lies on the study of three distinct filled polymer systems, their internal structure being all the more complex. The first system consists of a polymethyl methacrylate matrix filled with silica nanoparticles. The second system has polyamide 6 as a matrix and silica as fillers. The last system results from the clay introduction to polyamide 6/ First a morphological investigation enables to get insight into the filler influence on the surrounding polymer matrix. It also enlightens the various filler dispersion states (and its possible orientation within the sample geometry) with respect to the composite nature (in particular the inorganic particle size or its surface treatment) and its elaboration route. Then the study focuses on the role played by various morphological parameters (filler fraction, aspect ratio and dispersion state) on some mechanical properties, both elastic and plastic (through an investigation around the yield point). The latter properties were analysed on the various studied systems and compared. The experimental data were further confronted to some mechanical approaches, in order to better identify the morphological parameters leading to the observed macroscopic behaviours. Eventually, on the composites based on PA6, a possible sequence of the damage mechanisms occurring with increased elongation at room temperature was proposed, thanks to complementary experimental observations (through scattering and volume changes measurements). Given the involved parameters, each system was found to be characterised by a particular sequence of events

Following the proposals of the European Commission, to achieve the goals of emission reduction of carbon dioxide (CO2) from cars. To achieve this objective, automakers must reduce the weight of the car. Thus the supplier Faurecia, manufacturer of car seats desires to replace metal structures by structure plastic-metal hybrid (PMH). And they desire also to use a composite material to replace metal in order to reduce weight. Moreover in order to improve the adhesion strength at the interface piece hybrid structure,Atmospheric plasma technique was used.In this context, we studied the effects of plasma treatment on term of adhesion in the hybrid structure in order to provide the best condition of treatment. The objective of this study was to characterize the effect of plasma treatment by determination at the parameters in the process such as the scanning speed, the distance between the substrate and the plasma torch and the number of passes of the torch, then to predict the initiation of delamination under quasi-static loading test in specimen of single lap shear by using the criterion of rupture. The other objective was to study the micromechanical model to assess the reliability of them. And they will be applied to predict the mechanical behavior of Short Glass Fiber reinforced thermoplastic. In order to achieve the objectives presented, the several tests such as tensile test, single lap shear test and ARCAN-Mines test have been executed. In parallel, techniques acoustic emission (AE), infrared radiation (IR) and optical microscopy were used in order to follow the failure mechanisms of the specimen studied. Finally, the finite element method was used to simulate the tests and allow to verify the reliability of the failure criterion

Novel hybrid inorganic/organic systems based on methacrylate and polyhedral oligomeric silsesquioxanes (POSS ®) have been synthesised and characterised. The synthesis has been performed via either thermally or UV free-radical polymerization. Chemical characterisation has been done with NMR, NIR and SEC. The POSS have been found to be polymerizable with the organic monomers once a good dispersion is ensured. Structure and morphology, characterised by means of SEM, TEM, AFM and WAXS, have been shown to be mainly dependent on the dispersion of the POSS in the organic matrix. Depending on the POSS grade and concentration, one could obtain a wide array of structure-morphologies, from micro-aggregates to a very fine dispersion, probably to the molecular level. In turn, these different morphologies have an influence on the properties of the final systems. Thermal, thermomechanical and mechanical properties have been analysed. The POSS have been shown to change the crosslinking density of the thermosetting networks, while, in thermoplastic systems, the properties of the hybrid systems have been largely influenced by the nature of the organic ligands borne by the POSS

This work aims at studying the relationships structure – rheological and mechanical properties of polyamide12/organically modified clay nanocomposites. The effect of solid content and mixing conditions on melt state rheological and solid state mechanical properties was studied using numerous experimental investigation techniques. Linear and non-linear viscoelasticity allowed to characterize the melt state behavior of the nanostructured materials, wide angle X ray diffraction coupled with transmission electronic microscopy were used to characterize the structure; tensile tests were performed to characterize the mechanical behavior up to the total break. The results have clearly shown that both melt and solid state mechanical properties of nanocomposites depend strongly on the solid content and on the processing parameters. We have clearly shown the existence of a threshold solid volume fraction, at about 1%, separating two clay concentration regimes : - a dilute regime, where isolated clay entities govern the mechanical response of the nanocomposites. The rheological and mechanical properties depend on the nature, the number and the shape of these primary entities, which can be tuned by the processing parameters : mixing time and speed. - a concentrated regime, where the mechanical response is governed by a structure composed of “domains”. The rheological and mechanical properties depend on the size of these domains, which can be tuned by the processing parameters : mixing time and speed. However, the mechanical properties at break are disappointing, probably due to the presence of aggregates which induce stress concentration effects

The development of modern technologies requires that one use materials presenting high mechanical properties specific to their employment,but whose densities are low. The composite materials are materials which fulfil the preceding requirements. Because of their interest, the composite materials were initially used in aerospace, automotive, and construction industries. In composites, a class of particular interest ragarding the possibilities of design and development concern the sandwich structures resulting from a general assembly of a skin material with high stiffness and core materials of low density. The final properties of the materials are directly derived to the industry, many developments and studies in recent years have been aimed at optimizing the ratio mechanical performance over density. This thesis was undertaken with the same objective, but by having a strategy of optimization being focused more particulary on core materials. Our process is to reconsider in its entirety core materials and to propose a new concept of core complex which rests on the material stacking of different nature according to a quite precise sequence. The experimental results are correlated with those obtained by a theoretical approach based on a finite element method

The aim of this work is to propose fully bio-based composites for a potential application in the cabin interior, and compliant with the REACh regulations. The use of vegetable fibers as reinforcement into polymeric matrices is an encouraging way to decrease the environmental impact, end the weight as well. A new bio-based polyamide matrix, synthetized by Arkema - Polyamide meta-xylylene diamine 10 - was used in this work. A preliminary study on Polyamide 11/bamboo powder showed the introduction of the fillers did not modified the physical structure of the matrix. Moreover, the optimization of the mechanical properties occurs with no coupling agent. The continuous bamboo fibers/PA mXD 10 composites, which were also processed without coupling agent, present shear moduli superior than the one of the synthetic reference glass fibers/phenolic, with a gain of weight about 50%
