Le, Guen-Geffroy Antoine. "Marine ageing and fatigue of carbon/epoxy composite propeller blades." Thesis, Brest, 2019. http://www.theses.fr/2019BRES0104.
Full textThe current document presents the long term seawater ageing effect on the fatigue properties of carbon fibre reinforced epoxy marine propeller blades. Seawater uptake in the resin and the composite was identified to correspond to a Fickian diffusion. Calculations of the mass to saturation of the composite based on that of the resin reveal the presence of water in the composite’s porosities.Accelerated ageing of the pure resin highlighted three ageing phenomena: oxidation, plasticization and physical ageing. The last two were mechanically characterized separately and coupled with one another. Above all, it was shown that the presence of seawater accelerated the physical ageing kinetics by reducing the relaxation time. The composite was studied under different quasistatic and cyclic loadings.Few effects of seawater have been found for tensile stresses on fibre oriented loadings. This was not the case for transversely loaded composite that showed a non-negligible decrease of the mechanical properties for both static and fatigue loadings. This was also the case for flexure loading which was studied under four-point flexure. This latter test method was particularly studied due to the particular induced damage. The composite was studied under two delamination loadings: crack opening and inplane shear. It was observed that seawater decreased the critical strain energy release rates for both load cases as well of the fatigue resistance of both crack modes. Finally, the effect of physical ageing on the composite was studied and found to be non-negligible, demonstrating the necessity of taking it into account for both ageing and mechanical design

Full textResearch conducted to analyze the composite with pickling soil (SD), considered waste in mineral deposits, especially of limestone in the city of Almirante Tamandaré, the Metropolitan Region of Curitiba in this work, along with the sludge and marine dredging sediment from the Port of Antonina, State of Paraná, and use the common quicklime as binder belonging to the same region of Almirante Tamandaré. Various amounts of materials were used for the determination of twelve (12) composites. For the stripping soil content ranged from 30% and 60%, for the dredging material contents ranged from 20% and 50% and binder common quicklime content ranged from 15% to 30%. Were molded curing ages of 3 days, 7, 14, 28, 60, 90, 180 and 365 days. The increase in compressive strength during curing was derived from the chemical reactions of solid particles of raw materials in alkaline environment generating the new amorphous formations. Also the raw materials were analyzed in the SEM with EDS method, DRX and FRX, to obtain the chemical composition and formation structures of the new composite. All results of the uniaxial compressive strength, with 28 days of curing the environment of the twelve (12) compositions, obtained average results of 7.7 MPa, satisfactorily meeting the NBR 7170:1983 standard that determines the resistance to compression equal or above 4.0 MPa, for the production of building materials for sealing masonry without structural purposes. Proving the use of these composites in construction materials, especially for thread block or brick fences without structural purposes, without the need for cooking or heating energy project for the healing of parts, contributing to the environment and sustainability Environmental.

Full textRecently, Renewable Marine Energies (RME) has emerged as a tremendous opportunity for a real ecological and industrial choice to meet the growing demands for energy and also to fight global warming. The study conducted in this thesis is with in this framework of research and is focused on the investigation of one of the most promising categories of RMEs which is tidal current turbine. A new hydrofoil for the turbine was designed using BEM (Blade Element Momentum) methods and CFD (Computational Fluid Dynamics) calculations with improved hydrodynamic efficiency. Furthermore, a series of numerical studies were conducted to investigate and examine the damage behavior of composite materials under critical loadings by developing DLOAD and VUMAT routines. This numerical study assisted in understanding the problems of structural lightening, resistance to fatigue and impact loading, and other degradation phenomena of themechanical properties of a composite turbine in severe marine environments and solving the needs of the manufactures. Moreover, study about the dynamic behavior of a composite/composite bonded assembly was also conducted because joint assembly plays a vital role in reducing the mass of the structure which is of extreme relevance in the field of marine and offshore structures. Another important obstacle regarding the application of composite and bonded structures in marine was the control of hygro-mechanical coupling. Therefore in this context, additional campaign of tests was carried out on bonded composite specimens by studying the hygrothermal effect on their dynamic behavior at different deformation rates using Hopkinson bar method. This hybrid study of hygro-thermal effect of the dynamic properties of the bonded composites will aid in optimization of the structures and to move into the commercial phase with a substantial gain in LCOE (Levelized Cost of Energy) in future

Full textWhen the design requirements are either too stringent or are conflicting, no monolithic material solution exists. In such cases the selection of a multimaterial could be considered. The primary aim of this thesis is to provide a methodology for designing multi-materials with a prescribed arrangement of the constituent materials. The second objective is to apply this new methodology to the design of a submarine pipeline. From amongst the huge variety of multi-material arrangements available, this study focusses on multilayered stackings and therefore the design methodology becomes a method for selecting the materials of the stack and sizing the layers. This original approach is presented in detail using basic examples in order to match the steps of classical methods for selecting engineering materials. The constraints programming techniques were very useful for solving real multimaterial design problems. Applying this new method to the design of a submarine pipeline permits its validation and provides proof of its relevance
