Résumé :

Composite parts reinforced with unidirectional or 2D woven reinforcements have been widely used for many years in numerous industries from aerospace to automotive parts. Although their use is widespread, laminated reinforcements have some significant weaknesses that limit their usefulness, including poor interlaminar strength and high cost driven by the need for lengthy hand lay-up to create complex parts. Considerable effort has been put into developing three-dimensional composite reinforcement in order to alleviate these problems. This thesis focuses on materials produced via the weaving met

Résumé :

Damage development in transparent woven glass fibre reinforced epoxy laminates manufactured from two different commercial cloths has been investigated under quasi-static and cyclic loading. Of the two different cloths, one was woven using untwisted fibre bundles, the second cloth was woven using a fibre bundle which was formed by twisting three smaller bundles together. All laminates were fabricated using a wet lay-up process to impregnate two layers of cloth prior to curing. Uniaxial quasi-static tension and tension-tension fatigue tests were carried out on coupons from both sets of laminates

Résumé :

Three dimensional (3D) woven composites have attracted the interest of academia and industry thanks to their damage tolerance characteristics and automated fabric manufacturing. Although much research has been conducted to investigate their out-of-plane "through thickness" properties, still their in-plane properties are not fully understood and rely on extensive experimentation. The aim of this work is to study the electromechanical behaviour of three different fibre architectures of 3D woven composites "orthogonal (ORT), layer-to-layer (LTL) and angle interlock (AI)" loaded, in three differen

The recent development of CubeSat nano-satellites shows that it is an effective way to send a payload onto orbit, as it is a relatively inexpensive and quick access to space. If the small size of these satellites is their main advantage, it is also the principal source of problems when it comes to designing it. The control electronics, electric power system and the payload are limited in mass and have to t in a tiny ten-centimeter cube. The necessity of a compact deployable structure to hold the payload once the satellite reached its orbit is one of the principal subject of study for the desig

Efficient and accurate numerical simulation methods for the damage tolerance analysis and fatigue life prediction of fibre reinforced polymers are in high demand in industry. Problems arise in the development of such a simulation method due to the limitations from numerical methods, i.e., delamination modelling, and understanding of damage mechanism of woven fabric composites. In order to provide effective and accurate delamination modelling, a new crack modelling method by using the finite element method is proposed in this study.

Woven fiber-reinforced polymer composites have become superior materials of choice in advanced industries such as aerospace, energy and automotive. The low in-plane shear stiffness of woven fabrics provides them with high formability, and hence the characterization of this stiffness is of high impotence.

Les validations expérimentales confirment l'efficacité des modèles, offrant une caractérisation détaillée de la friction dans différentes conditions et

Résumé :

La presente ricerca è finalizzata a comprendere sperimentalmente e teoricamente i fattori che influenzano la formazione degli strain residui. Tali strain si verificano durante il processo di cura di lastre composite in fibra di carbonio. Il fenomeno degli strain residui che si sviluppano durante la produzione di materiali compositi in fibra di carbonio è uno dei problemi più significativi dell’Industria. La necessità di componenti di alta qualità per applicazioni avanzate richiede che i processi di produzione siano soggetti a gradi di precisione e monitoraggio sempre crescenti nel tentativo di
